Answer:
3072ft
Step-by-step explanation:
we have,
h(t)=-16t²+192t+2560
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For t=8 seconds
substitute the value of t in the function and find the value of h
h(8)=-16(8)²+192(8)+2560

1.
centre(h,k)=(-13,9)
radius (r)=6
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x+13)²+(y-9)²=6²
(x+13)²+(y-9)²=36you can write this equation too
x²+26x+169+y²-18y+81=36
x²+y²+26x-18y+169+81-36=0
x²+y²+26x-18y +214=0
is a required equation of the circle.
2.

PLEASE HURRYYY
Answer:
107 degrees
Step-by-step explanation:
All polygon degrees add up to 360
we know that this polygon has a angle of 90 and 56
subtract 90 and 56 from 360 to get 214
Then divide by 2 because there are 2 x angles
to get 107 degrees
Find Thin Mints in radians
Need help with math homework
Answer:
a) Thin mints = 1.885 radians
b) Savannah smiles cookies = 0.332 radians
Step-by-step explanation:
To convert an angle from degree to radians, the formula is given as :
x ° × π/180 = radians
Where x = angle to be converted
From the diagram we are to convert Thin mints and Savannah cookies to radians
a) Thin mints = 108°
Converting to radians
= 108° × π/180
= 1.8849555922 radians
Approximately = 1.885 radians
b) Savannah smiles cookies = 19°
Converting to radians
= 19° × π/180
= 0.331613 radians
Approximately = 0.332 radians

Given the following functions f(x) and g(x), solve
below:
(f/g)
(-5) and select the correct answer
f(x) = 2x - 20
g(x) = x - 1
05
0
-5
30
Answer:
-5
Step-by-step explanation:
Given the functions
f(x) = 2x - 20
g(x) = x - 1
f(x)/g(x) = 2x - 20/x-1
f/g(x) = 2x - 20/x-1
Substituting x = -5 int the result
f/g(5) = 2(5) - 20/5-1
f/g(5) = 10 - 20/4
f/g(5) = -10/4
f/g(5) = -5
Hence the result is -5

Activity 2 of 2
Part B: If Angle A and Angle B are supplementary
angles, what is measure of
Angle B?
A :90 °
B :28 °
C :180 °
D: 140 °
Answer:
If Angle A and Angle B are vertical angles,
what is value of x?
D. 8
If Angle A and Angle B are supplementary
angles, what is measure of
Angle B?
D. 140
Step-by-step explanation:
If Angle A and Angle B are vertical angles,
what is value of x?
Vertical angles are congruent thus
40° = 5x°
5x° = 40°
(5x / 5)° = (40 / 5)°
x° = 8°
If Angle A and Angle B are supplementary
angles, what is measure of
Angle B?
Supplementary angles add up to 180° or a straight line.
180° – 40° = 140°

The value of x is 15.
What is Right triangle?
A triangle in which one of the interior angle is 90° is called a right triangle.
Given that;
Sides of a right triangle are 12, 9 and x.
Now,
By the Pythagoras theorem;
x² = 12² + 9²
x² = 144 + 81
x² = 225
x = √225
x = 15
Thus, The value of x is 15.

A square has a diagonal that is 26 feet long.
What is the perimeter of this square?
answer:
52[tex]\sqrt{2}[/tex]
step-by-step explanation:
we can use the 45-45-90 triangle theorem for this: x, x, x[tex]\sqrt{2}[/tex]this is because this is a square
squares have two sides of the same length, and the diagonal is differentthe x's stand for the sides, whereas the x[tex]\sqrt{2}[/tex] stands for the diagonalx[tex]\sqrt{2}[/tex] = 26
x = 13[tex]\sqrt{2}[/tex]
now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 413[tex]\sqrt{2}[/tex] X 4 = 52[tex]\sqrt{2}[/tex]
