I don’t know
if you u need an actual answer....but brainliest?
D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
Let's solve your equation step-by-step.
5=(−4)(8)+b
Step 1: Simplify both sides of the equation.
5=(−4)(8)+b
5=−32+b
5=b−32
Step 2: Flip the equation.
b−32=5
Step 3: Add 32 to both sides.
b−32+32=5+32
b=37
Answer:
26
Step-by-step explanation:
Fitst, you substitute
f(2) = 3(2) + 20
f(2) = 6 + 20
f(2) = 26
your answer is 26
