The two functions below are used to represent the height of a rocket above the ground after it is launched. Which rocket reaches
a greater distance above the ground at its maximum height? Rocket A: y = -6x 2 + 96x Rocket B: y = -4x 2 + 80x Rocket reaches a maximum height that is greater than the maximum height of Rocket
2 answers:
Answer:
Rocket B reaches a maximum height that is greater than the maximum height of Rocket A.
Step-by-step explanation:
A graph quickly shows the answer to this question.
__
In vertex form, the equation for Rocket A is ...
y = -6(x² -16x +8²) +6(8²)
y = -6(x -8)² +384 . . . . . . . . . maximum height is 384 feet
__
The corresponding equation for Rocket B is ...
y = -4(x² -20x +10²) +4(10²)
y = -4(x -10)² +400 . . . . . . . . maximum height is 400 feet
Rocket B reaches a maximum height greater than that of Rocket A.

180 rabbits
Step-by-step explanation:
<u><em>The correct question is</em></u>
The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there last year?
we know that
900 rabbits represent 500% of last year population
Last year population represent 100%
so
using proportion
Find out how many rabbits represent a percentage of 100%
