Answer:
f(9) = 72
Step-by-step explanation:
f(9) means what is the value of f(x) when x = 9
9 > 6, thus f(x) = 8x
f(9) = 8 × 9 = 72
Using the concept of proportionality we shall solve for the unknown altitude as follows:
let the measure of the altitude be x:
24/16=x/6
solving for x we get:
x=24/16*6
x=9 feet
