Answer:
median
Step-by-step explanation:
The centre of every data set is the second quartile/50th percentile/median
You are essentially dividing 9a² from all terms in the expression.
Divide:
(27a²x² + 45a²x + 36a²)/(9a²) = 3x² + 5x + 4
3x² + 5x + 4 is your answer.

Answer:
1,030.11703766971
Step-by-step explanation:
Just use a calculator (windows + r and then type calc if your on windows or search up calculator)
Two ways to answer:
A. Using calculus:
H(t)=-16t^2+65t+3
To find maximum of H(t), equate H'(t)=0, or
H'(t)=-32t+65=0 => t=65/32=2.03125, or
t=2.0 s. to the nearest 10
B, Without using calculus, i.e. by completing the square
H(t)
=-16t^2+65t+3
=-16(t^2-65/16t)+3
=-16(t^2-2*(65/32)t+(65/32)^2)+3+(65/32)^2
=-16(t-65/32)^2+3+(65/32)^2
meaning the maximum occurs at (t-65/32)=0, or t=65/32=2.03125
Answer: t=2.0 seconds (to the nearest tenth)
