2)306 in³

3)210in³

Step-by-step explanation:

1) r = 5in h = 12in

5 * 12 * 3.14

2) L = 3 W = 8.5 H = 12

3 * 8.5 * 12

3) $\frac{1}{2}$ ( B = 5 W = 7 H = 12)

Sandra needs 6 pieces of rope, each measuring 8 inches in length. She is going to cut the 6 pieces from a rope that is 84 inches

36 inches of rope will be left because 6*8 is 48 and you subtract 48 from 84 to get 36.

The graph represents the function f(x) = x2 + 3x + 2.

Vladimir [108]

Reflection of a function
$S_x f(x)\rightarrow{-f(x)}$ reflection of f(x) about x-axis

So
$g(x)=-(x^2+3x+2)=-x^2-3x-2$

If f(6) if f(x)=x^2 / 3 + x

MakcuM [25]

Answer:

1) If the function is $f(x)=\frac{x^{2}}{(3+x)}$ , $f(6)=4$

2) If the function is $f(x)=x^{(2/3)}+x$ , $f(6)=9.30$

3) If the function is $f(x)=\frac{x^{2}}{3}+x$ , $f(6)=18$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

f(6) means that you must substitute x=6 into the function above.

1. If the given the function $f(x)=\frac{x^{2}}{(3+x)}$ , you obtain:

$f(6)=\frac{6^{2}}{(3+6)}=4$

2. If the function is $f(x)=x^{(2/3)}+x$

Then:

$f(6)=6^{(2/3)}+6=9.30$

3. If the function is $f(x)=\frac{x^{2}}{3}+x$

Then:

$f(6)=\frac{6^{2}}{3}+6=18$

The cost, in dollars, of producing x belts is given by C(x) = 634 + 18x - 0.071 x^2. Find the rate at which average cost is chan

o-na [289]

Answer:

When 324 belts have been produced, the average cost is changing at -28 dollars for each additional belt.

Step-by-step explanation:

The cost of producing x belts is given by:

$C(x) = 634 + 18x - 0.071x^{2}$

Find the rate at which average cost is changing when 324 belts have been produced.

This is $C'(324)$ . So

$C(x) = 634 + 18x - 0.071x^{2}$

$C'(x) = -0.142x + 18$

$C'(324) = -28$

So the correct answer is:

When 324 belts have been produced, the average cost is changing at -28 dollars for each additional belt.
