Answer:

3/32

Step-by-step explanation:

The first question should be 3/8 as there are 3 "1"s on the spinner. The answer to the last one is "3/32". You take the 3/8 chances to get a one and multiply that by 1/4 to get a "B". Once you multiply you get .09375 which is 3/32 when converted. Please let me know if this is incorrect.

The cost, in dollars, of producing x belts is given by Upper C (x )equals 970 plus 12 x minus 0.076 x squared. The revenue, i

umka21 [38]

Answer:

$68.44 for each additional belt

Step-by-step explanation:

The cost and revenue functions are:

$C(x) = 970+12x - 0.076x^2\\R(x) =43x^{\frac{3}{4}}$

The profit function, P(x), is given by subtracting the cost function from the revenue function.

$P(x) = R(x) - C(x)\\P(x)=43x^{\frac{3}{4}}+0.076x^2-12x-970\\$

The derivate of the profit function gives us the rate at which profit changes:

$\frac{dP(x)}{dx} =P'(x)=32.25x^{\frac{-1}{4}}+0.152x-12\\$

For x = 484, the rate of change is:

$P'(484)=32.25*484^{\frac{-1}{4}}+0.152*484-12\\P'(484) = \$68.44/belt$

Profit is increasing by $68.44 for each additional belt

What is the rate of change for both of these tables. 25 pts

Rudiy27

Answer:

For the table on the left the rate of change is $22.8$

For the table on the left the rate of change is $-2$

Step-by-step explanation:

The range of change is the slope. The slope can be found with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

<u>For the table on the left</u>

Choose two points. In this case you can choose (-1,-24), (4,90)

You can say that:

$y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4$

Substituting these values into the formula, you get:

$m=\frac{-24-90}{-1-4}\\\\m=22.8$

<u>For the table on the right</u>

Choose two points. You can choose (3,-6), (-6,12)

You can identify that:

$y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6$

Substituting these values into the formula, you get:

$m=\frac{-6-12}{3-(-6)}\\\\m=-2$
