Answer:
For first part, t= 0.18 sec or 3.4 sec.
For second part, t= 3.7 sec.
Step by step answer:
First part:
Set h(t) = 17and solve for tt.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
Answer:
(1,2) 1 represents how many days and 2 represents how many mm tall

Answer:
C (20,5)
Step-by-step explanation:
The committees should contain 5 persons each
The number of people are 20
Apply combination concept
where
²⁰₅C = 20! /[ {20-5}!*5! ]
=20! / 15!*5!
=15504 ------The number of 5 person committees that could be formed from a group of 20 people.
Answer:
86400 seconds
Step-by-step explanation:
1 year consists of 365 days. 1 day has 24 hours, each hour has 60 minutes and each minute has 60 seconds. 1 day = (24 hours/day) × (60 minutes/hour)(60 seconds/minute) = 86400 seconds
