What is the value of (f • g)(2)?
Alona [7]

Answer:

f(g(2)) = 1

Step-by-step explanation:

Another way to write this composite is f(g(2)).  We first have to compute g(2), then fit that value into f.  

g(2)=2^2=4.

g(2) = 4.  Now we have to find f(4):

f(4) = 4 - 3 = 1

A rectangle has a length 3 times the width. What is the perimeter in terms of x?
Marina CMI [18]

Answer:

Perimeter is equal to all four sides added together.

Length = 3W; L=3W

So

P = 2(W) + 2(L)  substitute the equation for length above you get

P = 2(W) + 2(3W)  and combine

P = 2W + 6W = 8W; put in what the perimeter is and solve for W

66 = 8W, so W = 8.25

W = 8.25, L = 24.75

The probability that an archer hits the target when it is windy is 0.4; when it is not windy, her probability of hitting the tar
stiks02 [169]

Answer:

x = 6

Step-by-step explanation:

The probability that this archer hits her first shot is given by t the probability of being windy and that she hits the shot added to the probability of not being windy and that she hits the shot:

P(H_{first}) = P(H_w)*P(W)+P(H_{nw})*(1-P(W))\\P(H_{first})=0.4*0.3+0.7*(1-0.3)\\P(H_{first})=0.12+0.49 = 0.61

If the probability that she hits the target on her first shot is 0.x1, the value of x is:

P(H_{first})=0.61=0.x1\\x=6

To find the area of a circle use the formula A=πr2
So . . .
A = π18²
A = π324
A = 1017.88
To find the circumfrence of a circle use formula C=2πr
So . . .
C = 2π18
C= 113.1
