check the picture below.
so we know Bethany's payrate, her slope is 11.75, namely $11.75/hr, for for every hour, she makes 11.75 bucks.
now, let's use those red-circled points, to get Grant's slope, and therefore his payrate,
low and behold, Grant makes 12.90 or 12.9 bucks every hour.
well, Bethany does 11.75 hmmm what's their difference?
12.90 - 11.75
1.15
so 12.90 is greater than 11.75 by 1.15, meaning, Grant makes 1.15 bucks more every hour than Bethany.
Answer:
The ball hit the ground at t=6 seconds
Step-by-step explanation:
we have
where
f(t) is he height of the ball in feet
t is the time in seconds
we know that
When the ball hit the ground, the height of the ball is equal to zero
so
For f(t)=0
solve for t
Factor the leading coefficient -16t
the solutions are
t=0, t=6
Remember that
For t=0 ----> f(t)=0 is the initial height of the ball
Fort=6 sec ----> f(t)=0
therefore
The ball hit the ground at t=6 seconds
