Answer:
19/2
Step-by-step explanation:
This problem is a problem desgined to test your basic understanding of Trigonomic functions and there applictoins.
Sec theta is the inverse of cos theta, which means sec theta is equal to adjecent / opposite.
They already gave you cos theta which is 2/19
We should know that from 0 to 90 degrees, sec theta is postive.
so sec theta is 19/2

The total change in yards for the two plays 21 yards lost
what are integers?Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.
Definition of IntegersAn integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043. A set of integers, which is represented as Z, includes:
Positive Numbers: A number is positive if it is greater than zero. Example: 1, 2, 3 . . .
Negative Numbers: A number is negative if it is less than zero. Example: -1, -2, -3 . . .
Zero is defined as neither a negative number nor a positive number. It is a whole number.
In first play= 14 yards lost= -14
In next play = 7 yards lost = -7
So,
the total change in yards is = -14 + (-7)
=-14-7
= -21 yards

i need help !!!!!!!!!
Answer:
a. 14
b. 10
c. 11
Step-by-step explanation:
You need to use the distance formula.
[tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}[/tex]
Ex: (1,2) and (1,16)
You will need to lable each
1st Point: 1 will be [tex]x_{1}[/tex] and 2 will be [tex]y_{1}[/tex]
2nd Point: 1 will be [tex]x_{2}[/tex] and 16 will be [tex]y_{2}[/tex]
Then you will need to plug it in
[tex]\sqrt{(1-1)^{2} +(16-2)^{2}}[/tex]
Which expression has a value of 8?
1. 720 divided by 9
2. 720 divided by 90
3. 7200 divided by 9
4. 7200 divided by 90
Answer:
720 divided by 90
Step-by-step explanation:
72 divided by 9 is 8. 720 divided by 9 is 80 because you're keeping the 0, but when dividing, take away the zeros if both numbers have a zero to make it easier

The vertices of a triangle are A (-2, 2), B (4,10), and C (0, -2). Find the equation of the line that contains
the median through point
The equation of the line is y =________
Answer:
y = 1/2 x + 3
Step-by-step explanation:
mid point of line BC = (2, 4)
slope of the line containing median (m) = 1/2
y intercept (b)= 3
since y = mx + b
y = 1/2x + 3
The median of a triangle is the line segment joining the any of the vertex to the mid-point of the opposite side of that vertex. The equation of the median through point A is given by y = 1/2x + 3.
What is a Median ?A median of a triangle is a line segment joining one of the vertex of the triangle to the mid-point of the opposite side.
The median of an equilateral triangle also an angular bisector.
Given that,
The coordinates of A = (-2, 2)
The coordinates of B = (4, 10)
The coordinates of C = (0,-2)
Thus the coordinate mid-point of BC is given by (4+0)/2,(10-2)/2 = (2,4).
Now, to find the equation of median through A there are two points (-2,2) and (2,4).
Thus the equation of median an be written as,
(y-2)/(x+2) = (4-2)/(2-(-2))
=> y - 2 = 1/2(x+2)
=> y = 1/2(x+2) + 2
=> y = 1/2 x + 3
Hence, the equation of the line is y = 1/2 x + 3.

Answer:
A: (3x+24):3x = 85:51
Step-by-step explanation:
85 seems to be the total (RT + TP). 51 seems to be just TP alone.
This means that for the side lengths above, it should be in this format:
(length of QP):(length of SP)
The length of QP is 3x+24, as 3x is SP and QS is 24.
The length of SP is just 3x.
I hope this made sense, please leave a comment if it didn't ^^'
Answer:
∆RPQ ~ ∆TPS
now
RP: TP=QP:SP
(34+51);51=(3x+24):3x
(3x+24):3x=85:51 is your answer
Ernie Bilko has a business idea. He wants to rent an abandoned gas station for just the months of November and December. He will convert the gas station into a drive-through Christmas wrapping
station. Customers will drive in, drop off their gifts, return the next day, and pick up their wrapped gifts. He needs $332,200 to rent the gas station, purchase wrapping paper, hire workers, and
advertise. If he borrows this amount at 61% Interest for those two months, what size lump sum payment will he have to make to pay off the loan? (Round your answer to the nearest cent.)
Correction is the question: 6[tex]\frac{1}{2}%[/tex]% = 6.5%
Answer:
Amount to be repaid is $335798.833
Step-by-step explanation:
Amount of loan = $332,200
Rate of interest = 6.5%
time = 2months = 2/12 = 1/6 years
The amount of interest is simple interest
SI = [tex]\frac{P * R * T}{100}[/tex]
=[tex]\frac{ 332200 * 6.5 *1 }{100 * 6}[/tex]
= $3598.833
Final amount to be repaid = 332200+ 3598.833
= $335798.833
A compound used to remove permanent
hardness of water reacts with HCl to
produce NaCl, CO2 and H2O? Identify
the compound.
Answer:
Well by looking at the products,it must be sodium bicarbonate (NaHCO3)
Step-by-step explanation:
but then sodium bicarbonate does not remove permanent hardness of water,that compound is washing soda(Na2CO3) which should not be confused with NaHCO3. So as it would appear,the premise of the question is wrong but there is a compound that reacts with HCl to give those products

if x^2+25y^2=416 and x-5y=-16 the value of xy is
a)16
b)8
c)-8
d)-16
Answer:
(a)
Step-by-step explanation:
Note the expansion of (x - 5y)² is
(x - 5y)² = x² - 10xy + 25y² , that is
(x - 5y)² = x² + 25y² - 10xy ← substitute given values
(- 16)² = 416 - 10xy
256 = 416 - 10xy ( subtract 416 from both sides )
- 160 = - 10xy ( divide both sides by - 10 )
xy = 16 → (a)

Does anyone know what this means in relation to triangle proofs?
Answer:
If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. This is an extension of ASA.

Lauren is twice Kristy’s age. The sum of Lauren and Kristy’s ages is 51. Which equation represents the sum of their ages?
A K + K + 2 = 51 B K + 2K + 2 = 51 C 2K = 51 D K + 2K = 51
Answer:
D. K+2K=51
Step-by-step explanation:
Since Lauren is 2 times Kristy's age, Lauren's age=2K
so, if the sum of the two is 51, then 2K+K=51
If you want to solve it, 2K+K=3K=51
51/3=K
17=K
34=L
Answer:
D K + 2K = 51
Step-by-step explanation:
Lauren is twice Kristy's age so it would be 2K cause you want to multi[ly, and then you have to add Kristy's age in the equation because their ages added together is 51

I need help with this finding x problem please show work
Answer:
The model represents the equation
-3x + 6 = 4x -8
Start by subtracting 6 from both sides.
-3x + 6 (-6) = 4x - 8 (-6)
-3x = 4x - 14
Subtract 4x from both sides
-3x - 4x = 4x - 4x - 14
-7x = -14
x = -14/-7
x = 2
