Answer:
h = -16t^2+60t+5
Step-by-step explanation:
We have given that:
Rachel’s ball is modeled by the equation h = –16t2 + 30t + 5.
Dominique throws his tennis ball with the same acceleration, a, from the same initial height, h = -16t2 + 30t - 5, but with an initial velocity, v, double that of Rachel’s.
We have to find:
Which equation best models the height of Dominique’s tennis ball?
<u>Solution:</u>
The equation we have been given is:
h = –16t2 + 30t + 5.
where -16 is the acceleration
30 is the initial velocity
5 is the initial height
So when the initial velocity is doubled then the final equation we get is:
h = -16t^2+60t+5
Thus the equation that models the height of Dominique's tennis ball is
h = -16t^2+60t+5

<span>Sixty percent of the days in the desert were hot and dry. Out of the 365 days, how many were hot and dry?
Solution is simple.
There are 365 days and 60% of those are hot and dry. What is 60% of 365?
365 x .60 = 219

Answer:
Claire is standing at a distance of 485.45 meters to Chloe.
Step-by-step explanation:
The track is a circular with a radius of 100 meters.
The total length of the circular track = length of the circumference of a circle
But, length of the circumference of a circle = 2r
So that,
total length of the circular track = 2r
= 2 × × 100
= 628.57
The total length of the circular track is 628.57 meters.
Thus,
the distance of Claire to Chloe = total length of the circular track - distance of Chloe to Claire
= 628.57 - 143.12
= 485.45
This means that Claire is standing at a distance of 485.45 meters to Chloe.
