Answer:
21.45
Step-by-step explanation:
A=bh
put in the values that you have.
A=2.75(7.8)
multiply and find the answer.
A=21.45
A= 1/2 bxh because if you are trying to find area you have to use the the formula A=1/2 bxh
For this case, what we must do is find three times the perimeter of the figure.
The length of the arch is given by:

Where,
r: radius of the circle
alpha: central angle in radians
We have then:

Then, the perimeter of the figure is:

Answer:
If David runs around the field three times, he covers a distance of 648 yards.
Answer:
Step-by-step explanation:
Let the exterior angle = x
Interior angle = 5x
x + 5x = 180 { interior angle and exterior angle are linear pair}
6x = 180
x = 180/6
x = 30
Interior angle = 5*30 = 150
Answer:
g(x) is obtained by shift the function f(x) down 7 units by subtracting 7 units from f(x).
Step-by-step explanation:
We are given that

We have to identify the transformation that occurs to create the graph of g(x).
To identify the transformation that occurs to create the graph of g(x)
We will subtract the 7 from f(x).
Let f(x) be any function

It means g(x) obtained by shift the function f(x) down k units by subtracting k units from f(x).
Therefore, g(x) is obtained by shift the function f(x) down 7 units by subtracting 7 units from f(x).
