Answer:
the height of the rock 3.2 seconds after it is propelled
Step-by-step explanation:
<u><em>The complete question is</em></u>
The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot
Let
t------> the time in seconds
h----> the the height of a rock after it is propelled by a slingshot in meters
we know that

For 
Find the value of h(t)

therefore
h(3.2) represent the height of the rock
seconds after it is propelled
see the attached figure to better understand the problem
Answer:
Hey what'sup?
You need to dig a little in, for what it's actually meaning
Here the total is 720 right?
Which came from the materials and the labors work in hourly basis
So it's like
Cost of the material + no of hours = bill
We don't know what the no of hours are, so let's assume it as 'x'
Hence the required equation is
375+35*x=720
35*x = 720-375
35*x = 345
Therefore x=345/35 =9.8
Therefore they worked for 9.8 hours or approximately 10 hours
Peace out
