Answer:

Step-by-step explanation:

1. Create the ratio 12:9

The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.

2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)

3. Add 9 to 9. (18)

We now have 21:18.

How is the derivative of a function related to the slop of the function?

statuscvo [17]

Hi there!

The derivative of the function is the slope of the function at a specific x-value, or its instantaneous rate of change.

For example, take the equation y = x².

Using the power rule, we get:

y' = 2x

If we plug in any x-value into this equation, we can find the slope of the function at any point.

Ex:

x = 0; 2(0) = slope of 0

x = 2; 2(2) = slope of 4

If the Revenue for the week is $2000, and labor cost consists of two workers earning $8 per hour who work 40 hours each, what is

slega [8]

So,

All you have to do is find the total labor cost and put it over the revenue.

We have two workers each earning $8/hr. (lousy), and they work 40 hrs./week.

2 * $8 = $16/hr.

$16/hr. * 40 hrs. = $640

$\frac{640}{2000}$

Cross out zeros.
$\frac{64}{200}$

Simplify.
$\frac{2^6}{2^35^2}$
$\frac{2^3}{5^2}$
$\frac{8}{25}$

Convert the denominator to 100.
$\frac{8}{25} * \frac{4}{4} = \frac{32}{100}$
$\frac{32}{100}$
=
32%

The labor cost is 32% of the revenue.

Answer:

First one is 41

Second one is 87

Step-by-step explanation:

Make the shaded part as a trapezoid which is (3+6)*10/2 you just have to get rid of 2*2. So you get 41 as the answer.

The unshaded part will be 16*8 then subtracts the shaded part which is 41. Then you get the answer 87.

Which equation describes the graph? Y=-|x+2| Y=-|x|+2 Y=-|x-2| Y=-|x|-2

Lera25 [3.4K]

Answer:

y = -|x|+2

Step-by-step explanation:

The graph represents y = |x| where the given graph opens upside down so it's negative and +2 translation towards the top
