Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
Answer:
150 votes were casted
Step-by-step explanation:
So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:
48/4=12
Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:
12+48=60
60/2=30
So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:
30*5=150
150 votes were casted
Answer:
Option D
Step-by-step explanation:
The most valid conclusion here is that the fact that running on a treadmill allows for a greater physical fitness with the television watching deterring the effect of the exercise. In as much as he only watches TV when running, it is not enough to conclude that TV can cause less physical fitness for Pablo.
Her rate of reading was = 51/2 /12 = 51/24 per hour
It means she red 51/24 pages in one hour
The answer is 1. This is because 5 is a prime number, so the only factors are 1 and 5. 5 is not a factor of 2.
