Answer:
-3x/10
Step-by-step explanation:
<span>h = -8t² + 40t
dh/dt = 0
⇒ d/dt(</span><span>-8t² + 40t) = 0
⇒ -16t + 40 = 0
⇒ 16t = 40
⇒ t = 40/16 = 2.5s
So it takes 2.5 seconds to reach highest point
h = -8×2.5² + 40×2.5 = -50 + 100 = 50
Ordered pair: (h,t) = (50,2.5)

Answer:
Step-by-step explanation:
On a certain hot summer's day, 691 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $1260.75. How many children and how many adults swam at the public pool that day?
Answer:
This cannot have an answer since this is a expression not a equation. If it was something like 4x+26=100, there will be a answer. but this cannot have an answer.
The graph of f(x) is given. And equation of g(x)= -f(x+2)
f(x+2) means f(x) will move 2 units left. And the negative in front means reflection on x axis.
