<h2>(25) 7th Grade Swimmers</h2><h2>25:80</h2>
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
Answer: C. 69(0.75)(.0.90)
Step-by-step explanation:
In order to find a discounted price you subtract the discount percentage as a decimal from 1 and multiply the outcome to the original price. For this case, 1-0.25=0.75 and 1-0.1=0.90. So your equation will be 69(0.75)(0.90)
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
