Answer:

C. 468mm²

Step-by-step explanation:

The formula for the surface area of rectangular prism is:

$A=2(wl+hl+hw)$

Let's break down our variables.

L = 12mm

W = 6mm

H = 7mm + 2mm = 9mm

Now we substitute our values in the formula:

$A=2((6)(12)+(9)(12)+(9)(6))$

$A=2(72+108+54)$

$A=2(234)$

$A=468mm^{2}$

Answer: labor force participation rate =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

$\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}$

i.e. $\text{labor force participation rate}= \dfrac{72000}{120000}$

$= 0.6\ or\ 60 \%$

The unemployment rate is computed as:

$\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%$

Hence, labor force participation rate =60%

unemployment rate = 6.67%

Which of the following pairs of functions are inverses of each other

Ghella [55]

Option (A) represents the function and its inverse of a function option (A) is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function and inverse of a function shown in the picture.

Checking for option (A):

$\rm f(x) = \dfrac{x}{4}+10 \ \ \ and \ \ \ g(x) = 4x -10$

Taking f(x):

$\rm f(x) = \dfrac{x}{4}+10$

To find the inverse of a function interchange the x and y variables:

f(x) → x

x → g(x)

$\rm x = \dfrac{g(x)}{4}+10$

Solving:

4x = g(x) + 10

g(x) = 4x - 10

Similarly, we can find the inverse of a function.

Thus, option (A) represents the function and its inverse of a function option (A) is correct.

X4y(4) = yx2(13), calculate (x+y)2

Delicious77 [7]

Please, for clarity, use " ^ " to denote exponentiation:

Correct format: x^4*y*(4) = y*x^2*(13)

This is an educated guess regarding what you meant to share. Please err on the side of using more parentheses ( ) to show which math operations are to be done first.

Your (x+y)2, better written as (x+y)^2, equals x^2 + 2xy + y^2, when expanded.

The question here is whether you can find this x^2 + 2xy + y^2 in your

"X4y(4) = yx2(13)"

Please lend a hand here. If at all possible obtain an image of the original version of this problem and share it. That's the only way to ensure that your helpers won't have to guess what the problem actually looks like.
