To find the unit rate of the rain per hour, we do:
3÷6= 0.5
So, the unit rate is 0.5 inch of rain/hour
This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):
Simplify:
Solve for dy/dx:
Now, plug in the given points:
Further simplification gives:
So,
your answer is 11/23 or
B.
Let x be the retail price of the TV
55% of x is 0.55x
Wholesale price = x - 0.55x
Wholesale price = x(1 - 0.55)
= 0.45x
The wholesale price is 0.45 times the retail price.

Answer:
$3277.23
Step-by-step explanation:
The future value of the CD with interest at rate r compounded semiannually for t years will be given by ...
A = P(1 +r/2)^(2t)
where P is the principal value.
For the given rate and time, this is ...
A = $2000(1 +0.05/2)^(2·10) = $2000(1.025^20) ≈ $3277.23
The value of the CD at maturity will be $3277.23.
