Q:6-Consider the function:
f(x)= -6e^-x + x
The relative minimum for this function is at:
Mark one answer:
x=0
x=10
x=-1/6
There is no relative minimum, because the first derivative is always positive.
None of the other answers.

Q:7-The position of a car is given by the equation

Q:8-A gun sends a bullet straight up with a launch velocity of 220 ft/s.
It reaches a height of s = 220t - 16t² after t seconds. What's the acceleration in m/s² of the block after it has been ejected?

Q:9-A projectile is shot up from a platform 5 m above the ground with a velocity of 150 m/s. Assume that the only force acting on the projectile is gravity that produces a downward acceleration of 9.8 m/s2. Find the velocity as a function of t.
Mark one answer:
v = -9.8t + 5
v = -5t + 9.8
v = -9.8t + 150
v = -5t + 150
v = -150 + 9.8

Q:10-Given the velocity function v(t) = t³ - t + 7, find the position at time x=2 with initial position x(0)=2.
