17. If the area of a square is 64 square centimeters, what's the length
of one side?
O A. 4 cm
OB. 8 cm
O C.32 cm
O D. 16 cm

B = 8cm

Step-by-step explanation:

We know the area of a square is given by

A = s^2  where s is the side length

64 = s^2

Take the square root of each side

sqrt(64) = sqrt(s^2)

8 =s

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
