Answer:
A would be equivalent
Step-by-step explanation:
if you think about it answers c and d would not make sense because they use 14 and not nine, so if you comapare the two you should get answer A

|-8|-|-1|
Answer:
The rocket will reach its highest point about 2.04 seconds.
Step-by-step explanation:
The function:

Models the relationship between the height of the rocket and the time after launch t in seconds.
Since this is a quadratic function, the rocket will reach its highest point at its vertex. The vertex of a quadratic is given by:

In this case, a = -4.9, b = 20, and c = 0. Thus:

The rocket reaches its maximum height after 10/4.9 or about 2.04 seconds.
Further Notes:
Then the maximum height of the rocket will be f(10/4.9):

875: 100% = 350: x%
875x = 350 * 100
875x = 35000
x = 35000/875
x= 40% - that is the percentage of female members
Which means that the percentage of the members who are male is 60%.
