Answer:

2.8 seconds

Step-by-step explanation:

Given that a ball is thrown directly up

Initial velocity u = 10 ft/sec INitial height = 100 ft

t = time from time of throw

The equation as

h(t) =-16t^2+10t+100

Since h(0) =100 we find that h is measured from earth

When the ball hits the ground h=0

So we have

h(t)=0 =-16t^2+10t+100

Use binomial formulae to solve this to get

t=2.832 or t =-2.207

Since time cannot be negative

we get t=2.832

At 2.8 seconds ball hits the ground

bezimeni [28]
The equation is given to us in slope intercept form. -34.85 is the slope and the y-intercept is 938.

Therefore, we can say:
The rate of change for the line of best fit is -34.85 which represents the decrease in number of available apartments per week since the complex opened.
The y-intercept is 938 which represents the number of apartments when it first opened.
