Answer: (c * d)(x) =
4x^3 + 18x^2 - 10x</h3>
Work Shown:
I'm assuming the dot means multiplication. If so, then,
(c * d)(x) = c(x)*d(x)
(c * d)(x) = [ c(x) ] * [ d(x) ]
(c * d)(x) = (4x-2)(x^2+5x) .... substitution
(c * d)(x) = 4x(x^2+5x) - 2(x^2+5x) ... distribute
(c * d)(x) = 4x(x^2)+4x(5x) - 2(x^2)-2(5x) ... distribute again
(c * d)(x) = 4x^3 + 20x^2 - 2x^2 - 10x
(c * d)(x) = 4x^3 + 18x^2 - 10x
Answer:
A
Step-by-step explanation:
1/8+1/8+1/8+1/8+1/8=5/8
Because unit fractions are fractions with the numerator is always going to be a one and the denominator is a positive integer.
Answer:
256 m^2
Step-by-step explanation:
area = b x h
16 x 16 = <em>256</em>
both combined would be <em>512</em>
Answer:
It's value after 10 years will be $10,507,833.3
Step-by-step explanation:
The equation for the value of the jet after t years is:
In which 
is the initial cost and r is the rate it decreases, as a decimal.
A corporate jet originally cost $17,550,000.
This means that 
If its value depreciates by 5 percent per year, what will its value be after 10 years?
This is C(10) when r = 0.05. So
It's value after 10 years will be $10,507,833.3
