You drop a rock off a bridge. The rock’s height, h (in feet above the water), after t seconds is modeled by h = -16t^2 + 541. What is the height of the rock after 2 seconds?

Answers

For this case we have the following equation:
 h = -16t ^ 2 + 541
 To answer the question, what we must do is evaluate the function for t = 2.
 We have then:
 h = -16 (2) ^ 2 + 541
 Rewriting we have:
 h = -16 (4) + 541h = -64 + 541h = 477 feet
 Answer:
 The height of the rock after 2 seconds is:
 h = 477 feet

8+9t-3+4 please help me​

Answers

Answer:

t = -1

Step-by-step explanation:

8 + 9t - 3 + 4    

Combine like terms

(8 - 3 + 4) + 9t

9 + 9t

9t + 9

Get t by itself

9t + 9 = 0

     -9    -9

9t = -9

Divide both sides by 9 to find t

t = -1
