Answer:
f(-1) = 2
Step-by-step explanation:
To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).
f(x)=x²-3x-2 becomes
f(-1)=(-1)² - 3(-1) -2, or
f(-1) = 1 + 3 - 2, or
f(-1) = 2

Distance travelled in heavy traffic = 40*1 = 40 miles
in light traffic = 60*2 = 120 miles
In total, he travelled = 40+120 = 160 miles
Answer:
volume = 684π m³ or 2148.85 m³
Step-by-step explanation:
volume = (π6² x 11) + (4/3π6³) = 396π + 288π = 684π m³ or 2148.85 m³
