If the total cost (C) is $18 multiplied by the hours, it would be C=18h

Answer:

C=18h

Step-by-step explanation:

Let

C------> represent the total cost

h-----> represent the number of hours

we know that

C=18h -----> linear direct variation that represent the situation

In this problem the constant of proportionality k is equal to the slope m of the line

so

m=18\frac{\$}{hour}

Step-by-step explanation:

If I understand the question right, G(t) = -((t-1)^2) + 5 and we want to solve for the average rate of change over the interval −4 ≤ t ≤ 5.

A function for the rate of change of G(t) is given by G'(t).

G'(t) = d/dt(-((t-1)^2) + 5). We solve this by using the chain rule.

d/dt(-((t-1)^2) + 5) = d/dt(-((t-1)^2)) + d/dt(5) = -2(t-1)*d/dt(t-`1) + 0 = (-2t + 2)*1 = -2t + 2

G'(t) = -2t + 2

This is a linear equation, and the average value of a linear equation f(x) over a range can be found by (f(min) + f(max))/2.

So the average value of G'(t) over −4 ≤ t ≤ 5 is given by ((-2(-4) + 2) + (-2(5) + 2))/2 = ((8 + 2) + (-10 + 2))/2 = (10 - 8)/2 = 2/2 = 1

Answer:

$357.42

Step-by-step explanation:

So first I multiplied $425.50 by 20%.

$425.50 * 0.20=  85.10

$425.50- 85.10= $340.40

$340.40 * 0.05 = $17.02

$340.40 * 0.07 = $23.828

$340.40 + 23.828 + 17.02= $ 357.42
