Step-by-step explanation:
What is the average rate of change for the function f(x)=3x^2 -5 on the interval −3 ≤ x ≤ −1 ?
Answer:
-12
Step-by-step explanation:
Let b = -1 and a = -3
The average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]
f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2
f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22
f(b) - f(a) = -2 - 22 = -24
b - a = -1 + 3 = 2
[tex]\frac{f(b) - f(a)}{b - a}[/tex] = -24/2 = -12
how to get a square root of a given number
Answer:
See below
Step-by-step explanation:
The square root of a number is defined as [tex]\pm y=\sqrt[2]{x}[/tex] where [tex](\pm y)^{2}[/tex] gives the original number. For example, [tex]\sqrt{4}=\pm2[/tex] because [tex]2^{2}=2*2=4[/tex] and [tex](-2)^{2}=-2*-2=4[/tex].
Example of Calculating Square Roots with Multiplication :
The square root of 9 is 3. The number 9 is an integer. This number comes from multiplying 3×3 which results in the number 9The square root of 25 is 5. The number 25 is an integer. This number comes from multiplying 5×5 which results in the number 25The square root of 81 is 9. The number 81 is an integer. This number comes from multiplying 9×9 which results in the number 81The square root of 100 is 10. The number 100 is an integer. This number comes from multiplying 10×10 which results in the number 100Example of Calculating Square Roots by Division

Answer:
EFG = 104°
GFH = 76°
Step-by-step explanation:
The sum of a linear pair is always equal to 180°
So lets solve for the variable n
2n + 32 + 4n + 16 = 180
6n + 48 = 180
6n = 132
n = 22
So now we know N
EFG = 4n + 16
EFG = 88 + 16
EFG = 104°
GFH = 2n + 32°
GFH = 44 + 32
GFH = 76°

Multiply 81.5 and 3.5
Answer:
285.25
Step-by-step explanation:
Basically we multiply them as normal numbers so,
815*35 = 28525
Then we take the amount of spots each number had to the RIGHT of the decimal point
81.5 = 1
3.5 = 1
1+1= 2
So: 28525. move to the left 2 times to get 285.25
Mr. Blake took 10 minutes to drive 5 miles,
He claims it will take half an hour to drive 15 more miles at the same rate.
Select all the statements that are true if Mr. Blake claim is true.
1. He will travel 2 miles per minute.
2. Hw would travel 50 miles in 25 minutes.
3. He will travel 1 mile for every 2 minutes.
4. He will travel at a rate of 30 miles per hour.
5. The ratio of miles driven to minutes traveled is 1:2.
Answer:
The correct answer is - 3, 4, and 5.
Step-by-step explanation:
Given:
distance = 5 miles
time to cover 5 miles = 10 minutes
If his claim is true then,
additional Distance = 15 miles
total distance will be = 15+5 = 20 miles
additional time = 30 minutes
total time = 10+30 = 40 minutes
Solution:
The speed of the vehicle can be calculated by the formula:
V = d/t
where V is speed or velocity
d = distance
t = time
Putting the final or total values in formula =
V = 20/40
= 1/2 (5th statement is true)
In an hour where 60 minutes are there, 1/2 = 30 miles per hour.
Thus, 3rd and 4th statement are true.

Find the probability that a randomly placed point falls within the smaller, inner circle.
The unshaded portion has a radius of 5 centimeters. The shaded path has a width of 8 centimeters.
5/8
25/169
64/78.5
15/24
Answer:
The probability that a randomly placed point falls within the smaller, inner circle is 25/64
Step-by-step explanation:
The remaining part of question is attached
Solution
The area of smaller circle is
[tex]\pi r^2 = 25 \pi[/tex]
The area of large circle is
[tex]\pi r^2 = 64 \pi[/tex]
Area of the shaded region
Area of large circle - area of small circle
[tex]64\pi -25\pi = 39\pi[/tex]
Probability that the point falls in the region of smaller circle is
[tex]\frac{25\pi }{64\pi } \\\frac{25}{64}[/tex]

Which statement best describe the diagonals of a rhombus?
A) Is a parallelogram with congruent diagonals
B) Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular
C) Is a parallelogram with the diagonals that intersect but does not form 90 degree
D) Is a parallelogram with diagonals that are congruent and perpendicular
Answer:
Is a parallelogram with congruent diag............ option is best describing better
The statement which best describes the diagonals of a rhombus is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.
What is Rhombus?A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.
So, rhombus is a parallelogram with all sides being equal.
The diagonals of a rhombus are not of equal length, so they are not congruent.
Also, the two diagonals of a rhombus cuts each other in to two equal halves and the intersecting angle is 90 degrees.
This means that the diagonals of a rhombus are perpendicular bisectors of each other.
Also, the diagonals bisect the pair of opposite angles through which the line passes.
Hence the correct option is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.

Here’s the revenue and expenses for the month. Calculate whenever Mia had profit or loss.
Answer:
Profit = $200
Step-by-step explanation:
Total revenue = $9,500
Fixed expenses = $9,000
Variable expenses = $300
Total expenses = Fixed expenses + Variable expenses
= $9,000 + $300
= $9,300
Total expenses = $9,300
Profit is when revenue is greater than expenses
Loss is when revenue is less than expenses
Mia made profit because her revenue is more than her expenses
Profit = Revenue - Expenses
= $9,500 - $9,300
= $200
Profit = $200
Ken is thinking of a number. Nine more than the product of 4 & the number is 73. Find Ken's number.
Answer:
x = 16
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
4x + 9 = 73
4x = 73 - 9
4x = 64
x = 64/4

A man works 6 hours overtime. His basic rate is $7.00 per hour. He is paid double time for overtime. What is his overtime pay
Answer:
His overtime pay is of $84.00.
Step-by-step explanation:
He is paid double time for overtime.
Basic rate of $7.00, overtime is double, so $7.00*2 = $14.00.
Worked 6 hours overtime:
So his overtime pay is:
$14.00*6 = $84.00
His overtime pay is of $84.00.
The three side lengths of four triangles are given which triangle is a right triangle
Answer:
Triangle 3: 3, 4 ,5
Step-by-step explanation:
Well, you can easily tell by 3, 4, 5 being a Pythagorean triple.
But you have to use the Pythagorean Theorem to solve this.
So you get the side lengths of the two shortest sides, and you add the squared versions of them together.
So: 3^2+4^2 and if that equals the biggest side:5^2 then it's a right triangle.

Hunter is organizing textbooks on his bookshelf. He has a Spanish textbook, a math textbook, a physics textbook, and a health textbook. How many different ways can he line the textbooks up on his bookshelf?
Answer: The different ways can he line the textbooks up on his bookshelf =24
Step-by-step explanation:
The number of ways to arrange n things = n!
Given: Number of different books = 4
Number of different ways to arrange 4 different books =4!
Number of different ways to arrange 4 different books= 4 x 3 x 2 x1
Number of different ways to arrange 4 different books = 24

Describe the end behavior of the function: y = -2x³ + x4 + 1 A. Even positive B. Odd positive C. Even negative D. Odd negative
Answer:
Even positive
Step-by-step explanation:
Given
[tex]f(x) = -2x^3 + x^4 + 1[/tex]
Required
The end behavior
We have:
[tex]f(x) = -2x^3 + x^4 + 1[/tex]
Rewrite as:
[tex]f(x) = x^4 -2x^3 + 1[/tex]
To describe the end behavior, we check the leading coefficient and the degree of the function.
We have:
Leading Coefficient = 1 (i.e. the coefficient of [tex]x^4[/tex])
Degree = 4 (i.e. the power of [tex]x^4[/tex])
The degree of the function is even (i.e. 4)
The leading coefficient is positive (i.e. 1)
Hence, the end behavior is Even positive
Find the value of x please I need help
Answer:
Step-by-step explanation:
113+90+90+12x+7=360(sum of four angles is always 360 degree)
300+12x=360
12x=360-300
x=60/12
x=5
Answer:
X = 5
Step-by-step explanation:
Shapes with 4 sides have angles that add to 360 degrees
So you have two right angles and 113 degrees.
This is
90+90+113=293
360-293=67
12x5=60
60+7=67
This means that x=5
