The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is

-16(0)^2 + 144 = 144ft

Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).

-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3

The domain is 0 to 3 seconds.

Mindy left at 8 a.M. And will arrive at 1 p.M.; jelly left at 8 a.M. And will arrive at 2 p.M. How many miles is the trip if Kel
uysha [10]

Answer:

300 miles

Step-by-step explanation:

The distance equation is D = RT

Where

D is the distance

R is the rate

T is the time

<u>Mindy</u>

8 am to 1 pm = 5 hours

<u>Kelly</u>

8 am to 2 pm = 6 hours

Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "

Now using the distance equation, we can write:

Mindy >>> D = RT >>> D = 5m

Kelly >>> D = RT >>>  D = 6(m-10) >>> D = 6m - 60

Since both the distances are equal, we can write:

5m = 6m - 60

m = 60

We want the distance, we know:

D = 5m

D = 5(60)

D = 300 miles

The distance is 300 miles
