Answer:
f(9) = 72
Step-by-step explanation:
This is a piecewise function. You have to establish what part to plug in your x value based on the designations given in the function. In this case, x=9.
9>6, so we would follow the bottom designation! When writing the function, turn every "x" into a 9.
f(x) = 8x
f(9) = 8(9)
f(9) = 72
Hope this helps you out :)!
Answer:828.96m^2
Step-by-step explanation:
radius(r)=8m
L=25m
π=3.14
total surface area of cone(tsa)=πxr^2+πxrxL
Tsa=3.14x8^2+3.14x8x25
Tsa=3.14x8x8+3.14x8x25
Tsa=200.96 + 628
Tsa=828.96
X-2 for x=-3
-3-2=-5, add dem negatives
The numerical value of the first check will be $2,357.

Answer:
4ab
Step-by-step explanation:
(a+b)^2-(a-b)^2
=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)
=a^2 + 2ab + b^2 - a^2 + 2ab - b^2
=2ab + 2ab
=4ab
