Applying the inscribed angle theorem, we have the missing measures as: 15. m<DEF = 127° 16. m(PL) = 62°
How to Apply the Inscribed Angle Theorem?15. Angle DEF is an inscribed angle while arc FGD is the intercepted arc. Thus, according to the inscribed angle theorem, we have:
m<DEF = 1/2(m(FGD)
Plug in the values:
6x + 37 = 1/2(19x - 31)
2(6x + 37) = 19x - 31
12x + 74 = 19x - 31
12x - 19x = -74 - 31
-7x = -105
x = 15
m<DEF = 6x + 37 = 6(15) + 37 = 127°
16. m<LMP = m<LNP
Plug in the values:
5x - 19 = 2x + 11
5x - 2x = 19 + 11
3x = 30
x = 10
m(PL) = 2(LMP) [based on the inscribed angle theorem]
Plug in the values:
m(PL) = 2(5x - 19)
Plug in the value of x:
m(PL) = 2(5(10) - 19)
m(PL) = 62°

Answers
Answer:
43
Step-by-step explanation:
The distance formula is
[tex] \sqrt{{(x2 - x1)}^{2} + (y2 - y1)^{2} } [/tex]
So
[tex] \sqrt{(25 + 18) ^{2} + ( - 7 + 7)^{2} } \\ = \sqrt{ {43}^{2} + 0 {}^{2} } = 43[/tex]
Answer:
43 unitsStep-by-step explanation:
The distance between the two given points can be found using the formula for the distance between two points in a coordinate plane,
which is d = √((x₂ - x₁)² + (y₂ - y₁)²). In this case, the x-coordinates of both points are the same (-7), so we only need to calculate the difference between their y-coordinates: d = √((0)² + (25 - (-18))²) = √(43²) = 43 units. Therefore, the distance between the two points located at (-7, -18) and (-7, 25) is 43 units
Richard bought 3 slices of pizza and 2 sodas for 8.75. Jordan bought 2p and 4s for 8.50. How much would 1p and 3s cost?
Answers
3p + 2s = 8.75 (Equation 1)
2p + 4s = 8.50 (Equation 2)
We want to find the cost of 1p and 3s, so we can set up a third equation:
p + 3s = C (Equation 3)
We need to solve for C. We can do this by first solving for p in terms of s in Equation 2:
2p + 4s = 8.50
2p = 8.50 - 4s
p = 4.25 - 2s
Now we can substitute this expression for p into Equation 3:
4.25 - 2s + 3s = C
4.25 + s = C
So 1p and 3s would cost C = 4.25 + s. To find the value of s, we can substitute the values from Equation 1:
3p + 2s = 8.75
3(4.25 - 2s) + 2s = 8.75
12.75 - 6s + 2s = 8.75
-4s = -4
s = 1
Therefore, 1p and 3s would cost C = 4.25 + s = 4.25 + 1 = 5.25.

We can see here that the equation that best models the situation is: B. 13 - (60h/23) = 10.
What is speed?Speed is a scalar quantity that describes how fast an object is moving, or the rate at which it covers distance. It is typically measured in units of distance per unit of time, such as miles per hour or meters per second.
Speed only tells us how fast an object is moving, without any information about the direction of motion or changes in direction.
We can see that if we find the time, h in hours, we will have:
h = (3 x 23)/60
Simplifying this expression gives us:
h = 69/60
Therefore, the equation is:
h = 1.15
(Note: 3 is gotten from 13 gallons - 10 gallons = 3 gallons that was used at that particular time and speed).
If we substitute h = 1.15 into our model equation, we will get the correct answer.
Thus, 13 - (60 × 1.15)/23 = 10.

Complete the following, using exact interest. (Use Days in a year table.)
Note: Do not round intermediate calculations. Round the "Interest" and "Maturity value" to the nearest cent.
Answers
A loan of $595 borrowed on June 15 and repaid on Dec 17 at an exact interest rate of 6%. The exact time between the two dates is 170 days, and the maturity value is $611.69 rounded to the nearest cent.
Using the Days in a year table, we can find the exact time between June 15 and December 17 as follows
June has 30 days in the table and July through November have 31 days each. December has 17 days until the loan is repaid. Therefore, the exact time is
30 + 31 + 31 + 30 + 31 + 17 = 170 days
Next, we can calculate the interest using the formula
interest = principal x rate x time / 365
where the principal is $595, the rate is 6%, and the time is 170 days.
Substituting these values, we get
interest = 595 x 0.06 x 170 / 365
interest = $16.69
Therefore, the exact interest is $16.69.
Finally, we can calculate the maturity value by adding the principal and the interest
maturity value = principal + interest
maturity value = $595 + $16.69
maturity value = $611.69
Therefore, the maturity value is $611.69 rounded to the nearest cent.

From experience, an airline knows that only of the passengers booked on a flight from New York to Los Angeles actually board their flight. A random sample of booked passengers from New York to Los Angeles is chosen. Find the probability that of them board their flight.
Do not round your intermediate computations, and round your answer to three decimal places.
Answers
Step-by-step explanation:
6 or 7.
that means either exactly 6 or exactly 7 out of the 10 board the flight.
these are non-depending (or non-overlapping) scenarios. so, for this "or" remained we can simply add the 2 individual probabilities P(6) and P(7).
P(6) is the probability of exactly 6 passengers out of 10 will board the flight.
because of the 75% certainty overall we can conclude that the probabilty for each booked passenger to board is 0.75 (75% means 75 out of 100 = 0.75).
and the probabilty to not board is
1 - 0.75 = 0.25
so, for a specific group of exactly 6 booked passengers out of 10 their probabilty to board is
0.75⁶ × 0.25⁴ = 0.000695229...
6 passengers board, 4 do not board.
but this is for only one possible grouping of 6 passengers out of 10.
since the sequence does not matter, and we have no repetitions (every passenger counts as 1), we have combinations :
C(10, 6) = 10! / (6! × (10-6)!) = 10!/(6!×4!) = 10×9×8×7/4! =
= 5×3×2×7 = 210
therefore,
P(6) = 210 × 0.75⁶ × 0.25⁴ = 0.145998001...
and for a specific group of exactly 7 booked passengers out of 10 their probabilty to board is
0.75⁷ × 0.25³ = 0.002085686...
7 passengers board, 3 do not board.
but this is for only one possible grouping of 7 passengers out of 10.
since the sequence does not matter, and we have no repetitions (every passenger counts as 1), we have combinations :
C(10, 7) = 10! / (7! × (10-7)!) = 10!/(7!×3!) = 10×9×8/3! =
= 5×3×8 = 120
therefore,
P(7) = 120 × 0.75⁷ × 0.25³ = 0.250282288...
so, the probability that either 6 or 7 booked passengers are actually boarding is
P(6) + P(7) = 0.396280289... ≈ 0.396

and the revenue function for selling x
items is R(x)=−0.5(x−120)2+7,200
. The maximum capacity of the company is 170
items.
Answers
1. Required profit function is P(x)= -0.5x² + 60x + 6850
2. The domain of P(x) is 20 - 4√205 ≤ x ≤ 170.
3. P(70) = 2650 and P(80) = 2600.
The company should choose to produce 70 items as it results in a higher profit.
4. The leads to a decrease in profit, which is why the company makes less profit when producing 10 more units.
What is profit function?
A profit function is a mathematical formula that describes the relationship between the level of production or sales and the resulting profit of a business. The profit function takes into account the costs of production, including fixed costs and variable costs, and the revenue generated by the sale of goods or services.
1. The profit function P(x) is given by subtracting the cost function C(x) from the revenue function R(x):
P(x) = R(x) - C(x)
= [−0.5(x−120)²+7,200] - [50x+250]
= -0.5x² + 60x + 6850
2. The domain of P(x) is the set of all possible values of x for which the profit function P(x) makes sense. Since P(x) involves subtracting the cost function from the revenue function, it only makes sense to calculate P(x) when the revenue generated from selling x items is greater than or equal to the cost of producing x items. Therefore, the domain of P(x) is the set of all x such that R(x) ≥ C(x),
R(x) ≥ C(x)
-0.5(x−120)²+7,200 ≥ 50x+250
-0.5x²+60x+6850 ≥ 50x+250
-0.5x²+10x+6600 ≥ 0
Solving for x, we get:
x ≤ 20 - 4√205 or x ≥ 20 + 4√205
Since the maximum capacity of the company is 170 items, the domain of P(x) is the intersection of the above solution and the maximum capacity, i.e. x ≤ 170. Therefore, the domain of P(x) is 20 - 4√205 ≤ x ≤ 170.
3. To find the profit when producing 70 items, substitute x = 70 into the profit function P(70) = -0.5(70)² + 60(70) + 6850
= 2650
To find the profit when producing 80 items, substitute x = 80 into the profit function P(80) = -0.5(80)² + 60(80) + 6850
= 2600
Therefore, the company should choose to produce 70 items as it results in a higher profit.
4. The profit function P(x) is a quadratic function with a negative leading coefficient (-0.5), which means that it opens downwards. This implies that the profit function reaches its maximum value at the vertex of the parabola, which occurs at x = -b/2a, where a = -0.5 and b = 60. Therefore, the vertex occurs at x = -60/-1 = 60. This means that the maximum profit occurs at x = 60.
When the company produces 10 more units (i.e. x increases by 10), it moves away from the optimal production level of 60 and closer to the maximum capacity of 170. As a result, the cost of production increases while the revenue generated from selling those extra units decreases due to diminishing returns. This leads to a decrease in profit, which is why the company makes less profit when producing 10 more units.

Purchase 400 motors per month what is percent saved if you order 800 every 2 months round to nearest tenth
Answers
Let's assume that the unit price of the motors is $100. If you order 400 motors per month, the total cost is:
400 motors/month x $100/motor = $40,000/month
If you order 800 motors every two months, the total cost is:
800 motors/2 months x $100/motor = $40,000/2 months = $20,000/month
The cost savings associated with the larger order is:
$40,000/month - $20,000/month = $20,000/month
To calculate the percentage saved, we divide the cost savings by the original cost and multiply by 100:
$20,000/month / $40,000/month x 100 = 50%
Therefore, you can save 50% by ordering 800 motors every two months instead of 400 motors per month.

Diane Warner can rent a minivan for $24.95 per day plus $0.15 per mile, or she can rent a
large van for $289 per week with no additional charge for mileage. If she plans on renting the
car for 7 days and driving a total of 1,200 miles, which vehicle is a better buy?
Answers
In this case, renting the huge van would be a more cost-effective option because it would run you $289 as opposed to $354.65 for the minivan.
To compare the costs of renting the minivan and the large van, we need to calculate the total cost for each option.
For the minivan, the cost per day is $24.95 and the cost per mile is $0.15. So, for 7 days and 1,200 miles, the total cost would be:
Total cost = 7($24.95) + 1,200($0.15)
= $354.65
For the large van, the cost is a flat rate of $289 per week with no additional charge for mileage. So, for 7 days and 1,200 miles, the total cost would be:
Total cost = $289
Therefore, renting the large van would be a better buy in this scenario, as it would cost $289 compared to $354.65 for the minivan.

Answers
the speed of the train in km/h is 40.32 whereas the speed of the train in m/s is 11.2.
(i) To find the speed of the train in km/h, we can use the formula:
speed = distance/time
Here, the distance travelled by the train is 16.8 km, and the time taken is 25 minutes, which is equivalent to 0.4167 hours (since 1 hour = 60 minutes). Substituting these values in the formula, we get:
speed = 16.8 km/0.4167 hours
speed = 40.32 km/h (rounded to two decimal places)
Therefore, the speed of the train in km/h is 40.32.
(ii) To find the speed of the train in m/s, we can convert the speed in km/h to m/s by multiplying by 1000/3600 (since 1 km/h = 1000 m/3600 s). Using the speed of 40.32 km/h from part (i), we get:
speed = 40.32 km/h * 1000 m/km / 3600 s/h
speed = 11.2 m/s (rounded to one decimal place)
Therefore, the speed of the train in m/s is 11.2.
If the speed limit is 55 km/h, we cannot directly determine the distance travelled by the train without additional information. The distance travelled by the train would depend on the time it took to travel at the given speed limit.

Therefore, by regular induction, we have proved that [tex]A(1, n) \leq 2^n[/tex] for all positive integers n.
b.) A power tower with one level is defined as a, and a power tower with (k + 1) levels is defined as a raised to the power of a power tower with k levels.
c.) [tex]A(2, n) \leq 2[/tex] ↑↑ n for all positive integers n, where ↑↑ denotes power tower notation.
d.) The recursive definition of a triple arrow-up notation for power towers is:
a ↑↑↑ 1 = a (base case)
a ↑↑↑ (k + 1) = a ↑↑ (a ↑↑↑ k) (recursive step)
This definition states that a triple arrow-up notation with one level is equal to the base value "a", and a triple arrow-up notation with (k + 1) levels is equal to "a" raised to the power of a triple arrow-up notation with "k" levels.

Answer:
radius = 72.00 units
Step-by-step explanation:
The general formula for circumference (C) of a circle is C = πd, where d is the diameter. The formula using 3.14 for π is C = 3.14d The diameter (d) is simply twice the radius (r) as d = 2r
Thus, we can rewrite the formula for circumference in terms of radius as C = 3.14(2r)
To solve for r, we can divide the circumference we're given by the product of 3.14 and 2 to find r:
[tex]C/(2*3.14)=r\\452.16(2*3.14)=r\\452.16/6.28=r\\72=r[/tex]

Question 5The range of the given function has one restriction, its denominator can't be zero, hence:
3x + 4 ≠ 0 ⇒ 3x ≠ - 4 ⇒ x ≠ - 4/3Therefore the function can get any value but zero:
y ≠ 0The matching answer choice is D.
Question 6Linear function is f(x) = mx + b.
Reciprocal of a function f(x) is 1/f(x).
So the reciprocal of linear function has a form of f(x) = 1 / (mx + b).
The only answer choice in same form is D.
Question 9Substitute x = - 5/3 into function to get:
[tex]f(x)=\cfrac{1}{3*(-5/3)+5} =\cfrac{1}{-5+5} =\cfrac{1}{0}[/tex]This is undefined value, therefore it represents the vertical asymptote.
The function gets close to - ∞ when x → - 5/3 from left and gets close to +∞ when x → - 5/3 from right (see attached graph).
Therefore the correct choice is B.
The distance between Eilat and Jerusalem is 292 kilometers. Give this distance in miles. Round the answer to the nearest tenth.
Answers
The distance between Eilat and Jerusalem is 181.4 miles.
To convert kilometers to miles, we need to multiply the number of kilometers by 0.621371, which is the conversion factor from kilometers to miles. Therefore, to convert the distance between Eilat and Jerusalem from kilometers to miles, we can use the following formula:
distance in miles = distance in kilometers × 0.621371
Substituting the given distance of 292 kilometers into the formula, we get:
distance in miles = 292 km × 0.621371 = 181.417852 miles
Rounding this answer to the nearest tenth, we get:
distance in miles ≈ 181.4 miles
Therefore, the distance between Eilat and Jerusalem is approximately 181.4 miles.

The television show Pretty Betty has been successful for many years. That show recently had a share of 15, which means, that among the TV sets in use, 15% were tuned to Pretty Betty. An advertiser wants to verify that 15% share value by conducting its own survey, and a pilot survey begins with 11 households have TV sets in use at the time of a Pretty Betty broadcast. Find the probability that none of the households are tuned to Pretty Betty. P(none) = Find the probability that at least one household is tuned to Pretty Betty. P(at least one) = Find the probability that at most one household is tuned to Pretty Betty. P(at most one) =
Answers
The probabilities will be :
P(none) = 0.018
P(at least one) = 0.982
P(at most one) = 0.187
What are the probabilities?Pretty Betty share is 15%, the probability that any one household is tuned to the show will be: 0.15.
To find the probability that none of the households are tuned to Pretty Betty will be:
P(none) = 0.85¹¹
≈ 0.018
So, to find the probability that at least one household is tuned to Pretty Betty, i use the complement rule as well as subtract the probability of none of the households being tuned to the show from 1:
P(at least one)
= 1 - P(none)
≈ 1 - 0.018
≈ 0.982
So, to find the probability that at most one household is tuned to Pretty Betty:
P(at most one) = P(none) + P(one)
= 0.85^11 + 11(0.15)(0.85^10)
≈ 0.187
Hence, the probabilities will be :
P(none) = 0.018
P(at least one) = 0.982
P(at most one) = 0.187

Answers
Hence, the value of CosФ + Cos (2π+Ф) + Cos (4π+Ф) is 0.6 .
What is Cosine function ?The cosine function One of the fundamental trigonometry functions is cos x as the others being the co-secant, cotangent, secant, sine, and tangent. Let theta represent the angle that can be calculated by rotating the unit circle's arc anticlockwise from the x-axis. Cos theta is the arc endpoint of horizontal coordinate after that.
What is the trigonometry identities?trigonometric functions are used in an expression or equation, trigonometric Identities are helpful. For every value of a variable appearing on both sides of an equation, a trigonometric identity is true. Certain trigonometric functions such as sine, cosine, and tangent of one or more angles are involved geometrically in these identities.Three main are trigonometry functions are sine, cosine, and tangent, while the other three are cotangent, secant, and co-secant. All six trigonometric functions serve as the foundation for the trigonometric identities.
Given, CosФ = 0.2,
thus we can use the trigonometric identity:
cos(2 n π+Ф) = cosФ
where any integer n is used. Therefore:
Cos(2 π+ Ф) = CosФ
cos (4π+Ф) = cosФ
These values, put into the given expression
than we get,
cos Ф+ cos (2π+Ф) + cos (4π+Ф) = cos Ф+ cosФ + cosФ.
= 3 cosФ
= 3×0.2
= 0.6
So,CosФ + Cos (2π+Ф) + Cos (4π+Ф) = 0.6
