Question

The equation h=4+7t can be used to determine the height of a flag (h, In feet) after t seconds.

A) What Is the starting height of this flag?
B) What Is the speed of this flag?

Answer 1

4

7

Explanation:

Part A

The starting height of the flag occurs when t = 0

h = 4 + 7*0

h = 4

So the starting height is 4 feet.

Part B

The speed of the flag is the slope of the line which is 7. So every second the flag is ascending, the flag goes up 7 feet per second.
