The answer D she ate 1 each day
9
if a b 9 are in GP
b÷a = 9 ÷ b
b^2 = 9a
if a - 1 b 9 are in AP
2b = a+8
b = a+8÷2
substitute
b is equal to a + 8 by 2 in b square equal to 9 a
(a+8÷2)^2 = 9a
a^2+16a+64 = 36a
a^2 -20a +64 =0
(a-16) (a-4) =0
a= 16 or a=4
when a=16 b= 12
when a=4 b= 6
Value of a and b are given above
The values of for which the rocket's height is 29 meters are 0.75 and -0.67.

What is a velocity?</h3>
Velocity can be described as a vector quantity having both direction and magnitude which is the distance traveled per time.
We were given the rocket's height h as which is an equation, and we were been given the height which is the value that can be input into the equation as is 29 meters , then we can proceed to simplify the equation as
29=57t-5t^2
then we will have
with the use of quadratic formula the values of t are : 0.75 and -0.67
Then we can chose 0.75 seconds
Therefore, after the calculation with the use of the quadratic equation, we can come into conclusion that the values that are required in the question are 0.75 and -0.67.
