Answer:
6.81s
Step-by-step explanation:
First you must know that the velocity of the body is zero at the maximum height.
v =dy/dx
v= -32x+218
Since v = 0
-32x+218 =0
32x =218
x= 218/32
x = 6.81s
Hence the rocket reaches its maximum height after 6.81s
103
it has to add up to 180 so
180-77=103
B
The equation is in slope-intercept form, so the slope is the coefficient of x. Since the coefficient of x is negative, so is the slope.
