Ihave the other two answers. i just need the maximum height.

You have the maximum height happens at 5 seconds.

Replace t with 5 and solve for h(t):

h(5) = -0.2(5)^2 + 2(5)

h(5) = -0.2(25) + 10

h(5) = -5+10

h(5) = 5

The maximum height is 5 feet.

i can you with this question sweetie!

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
