Answer:

A.

Step-by-step explanation:

The formula for circumference is:

C=2\pi r

We know that the circumference is 8π inches. So, substitute 8π for C:

8\pi =2\pi r

Solve for r. Divide both sides by 2π. So:

r=\frac{8\pi}{2\pi}=4

Therefore, the radius is 4 inches.

Hence, our answer is A.

Solve the following two equations. Show all of your
Elena L [17]

Step-by-step explanation:

Given that,

Two equations,

3x + 11 = 11 .....(1)

And

3(x - 3) = 45

or

3x-9=45 ....(2)

Subtract 11 on both sides of equation (1).

3x + 11-11 = 11-11

3x=0

x = 0

Add 9 to both sides of equation (2)

3x-9+9=45+9

3x = 54

x = 18

Hence, the solution of equation (1) is x=0 and form equation (2) x = 18.

3. f(-6) = 12+1 =13


 f(-2) = 4+1 = 5


f(0) =1


Range {1,5,13}


4.  f(-2) = (-2)^3+1 =-7


  f(-1) = (-1)^2 +1 =0


f(3) = (3)^3 +1 = 28


Range = {-7,0,28}


5.the sequence is arithmetic


d= -11+19 = 8


an = a1 + d(n-1)


an = -19 +8(n-1)


6.l =w+5


a =l*w


a(w) =(w+5) * w


a(w)= w^2 +5w


f(w) = w^2 +5w


f(8) = 8^2 +5(8)


f(8) = 64 +40


f(8) =104 in^2
