Answer:
0
Step-by-step explanation:
3x - 9 if x = 3
Substitute:
3(3) - 9 =
9 - 9 = 0
This can be written as a function: f(x) = 3x - 9
f(3) = 3x - 9
f(3) = 3(3) - 9
f(3) = 9 - 9
f(3) = 0

Answer:
Step-by-step explanation: the pattern is going positive to negative and going further away from zero so the next term would be -3
The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so

The formula you use to find the surface area of a sphere is A=4 π r^2
4×π = 12.5663706143
r = 4
4^2 = 16
12.5663706143 × 16 = 201.061929829
Final answer: the surface area is about 201 ft.
