H (t) = - 16t ^ 2 + 16t + 480
For this case, the first thing to do is to match the polynomial to zero to find the roots.
We have then:
0 = -16t ^ 2 + 16t + 480
From here, we obtain the following roots of the polynomial:
t1 = -5
t2 = 6
We ignore the negative root because the time is always greater than zero.
Answer:
it takes Rose to hit the water about
t = 6 seconds
To solve add the ratio together and you get 10. 25/10 = 2.5
Now 2*2.5: 3*2.5: 5*2.5
= 5 : 7.5 : 12.5
Answer:
Step-by-step explanation:
Since the ant travels at a constant speed, we can set up the following proportion:
, where 
is the distance the ant can travel in 7 minutes.
Solving for , we get:
.
The answer is 60
because first you subtract 10 on both sides
then multiply 4 on both sides getting v=60
Answer:
"Lines s and t have slopes that are negative reciprocals of one another."
