92 inches² paper would be needed to wrap the prism completely.

The total region or area covered by all the faces of a rectangular prism is defined as the surface area of a rectangular prism. A rectangular prism is a three-dimensional shape. It has six faces, and all the faces are rectangular-shaped. Therefore, both the bases of a rectangular prism must also be rectangles.

Given here: The dimensions of the rectangular prism are 8,3,2 in inches.

Total surface area of a rectangular prism = 2(lb + bh + lh)

Thus TSA= 2(24+16+6)

               =92 inches²

Hence, 92 inches² paper would be needed to wrap the prism completely.

Remember to divide, multiply, subtract, and drop down until each digit in the dividend has been divided in long division problems. The solution to the division issue is the quotient.

Long division is explained in the following steps:

Put the dividend and the divisor in their proper places.

Take the dividend's first digit from the left.

If this digit is more than or equal to the divisor, divide it by the divisor and write the quotient on top.

To calculate the difference, write the product below the dividend and subtract the result from the dividend. If this difference is less than the divisor and no numbers remain in the dividend, this is termed the residual and the division is completed. If there are more digits in the dividend to be handed down, we repeat the operation until there are no more digits more digit left in the dividend.

The equation of the line in point-slope form is y = -5x - 28.

What is the point-slop?

The point-slope form is a way to express the equation of a straight line. It's an alternate form of the slope-intercept form y = mx + b. In point-slope form, the equation of a line is represented as y - y1 = m(x - x1) where (x1,y1) is a point on the line and m is the slope of the line, which represents the steepness of the line and the direction it's going (positive, negative or zero). By using this form, we can find the equation of a line that passes through a given point and has a known slope.

The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line, and m is the slope of the line.

To write the equation of a line that passes through the point (-5, 7) with a slope of -5, we can plug in the given values:

y - 7 = -5(x + 5)

Simplifying:

y = -5x - 35 + 7

y = -5x - 28

Hence, the equation of the line in point-slope form is y = -5x - 28.

Using Pascal's triangle the expansion of the expression [tex](5x+5)^3[/tex] is [tex]125x^3+375x^2+375x+125[/tex].

What is Pascal's triangle?

The triangle can be used to calculate the coefficients of the expansion of  [tex](a+b)^n[/tex] by taking the exponent n and adding 1. The coefficient will correspond with line n+1 of the triangle.

Here for [tex](5x+5)^3[/tex] , n= 3 so the coefficient of the expansion will correspond with line 4.

The expansion follow the rule ,

[tex](a+b)^n=c_{0}a^nb^0+c_{1}a^{n-1}b^1+c_{n-1}a^1b^{n-1}+c_{n}a^0b^n[/tex]

The values of the coefficients, from the triangle, are 1-3-3-1.

=> [tex]1a^3b^0+3a^2b+3a^1b^2+1a^0b^3[/tex]

Here substitute a=5x and b=5 then,

=> [tex]1(5x)^35^0+3(5x)^25+3(5x)^25^2+1(5x)^15^3[/tex]

=> [tex]125x^3+375x^2+375x+125[/tex]

The value of x from the logarithmic equation are x = 1/3 and x = 27

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the equation be represented as A

Now , the value of A is

log₃ ( x ) - 3 logₓ ( 3 ) = 2   be equation (1)

Applying the logarithm rules , we get

log₃ ( x ) - 3/log₃ ( x ) = 2

Let the value of log₃ ( x ) = t

So , Substituting the values in the equation , we get

t - 3/t = 2

On simplifying the equation , we get

t = 3 and t = -1

Substituting the value of t in the equation , we get

b)   [tex]f^{-1}(x)[/tex] = 2x-3.

c) [tex]f^{-1}(12)[/tex] = 21.

What is inverse function?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

The output of a function is returned by the inverse function, which also returns the initial value.

Consider the inverse relationship between the functions f and g: f(g(x)) = g(f(x)) = x. The initial value is fetched via a function that is its inverse.

Here the given function f(x) = [tex]\frac{x+3}{2}[/tex]

a) Put x= 2 into f(x) then

=> f(2) = [tex]\frac{2+3}{2}[/tex]

=> f(2) = [tex]\frac{5}{2}[/tex]

b) Now to find inverse function , take y=f(x) then

=> y = f(x)

=> y = [tex]\frac{x+3}{2}[/tex]

Now interchange x and y and solve for y then,

=> x = [tex]\frac{y+3}{2}[/tex]

=> 2x= y+3

=> y = 2x-3

Then y = [tex]f^{-1}(x)[/tex]  

=>  [tex]f^{-1}(x)[/tex] = 2x-3.

c) Now put x=12 into  [tex]f^{-1}(x)[/tex]  = 2x-3 then

=>[tex]f^{-1}(12)[/tex] = 2(12)-3 = 24-3 = 21.

=>[tex]f^{-1}(12)[/tex] = 21.

Hence the answers are ,

a)  f(2) = [tex]\frac{5}{2}[/tex]

b)   [tex]f^{-1}(x)[/tex] = 2x-3.

c) [tex]f^{-1}(12)[/tex] = 21.

If he uses 875 kwh per month, he will pay about $81

The correct answer is an option (d)

Current use plan:

6.5 cents/kwh for the first 600 kwh

12 cents/kwh for the next 600 kwh

If the rates go up 1 cent in each category, the new rates would be:

7.5 cents / kWh for the first 600 kWh

13.0 cents / kWh the next 600 kWh

Given that he he uses 875 kwh per month.

We need to find the amount he will pay.

For first 600 kwh he will pay 7.5 cents/ kWh.

Then remaining rates would be 875 kWh - 600 kWh = 275 kWh

so, the expression for the total cost would be,

(600 × 7.5) + (275) × 13.0

The sampling distribution of the sample mean for samples of size 16, then, is 3.2 pets, which is the same as the mean number of pets owned by the population of students at the high school.

The mean number of pets owned by the population of students at a large high school is 3.2 pets per student with a standard deviation of 1.7 pets. To better understand this population, a random sample of 16 students will be taken and the mean number of pets for the sample will be calculated.

This will provide us with the mean of the sampling distribution of the sample mean for samples of size 16.

To calculate this, we will first calculate the standard error of the mean, which is the standard deviation of the sample mean. This is calculated by dividing the population standard deviation (1.7 pets) by the square root of the sample size (16), resulting in a standard error of the mean of 0.43.

This means that the standard deviation of the sample means is 0.43 pets.

In the given question, we have to find the solution to this system of linear equations 2x+3y=3 and 7x-3y=24.

The given equations are:

2x+3y=3...…….(1)

7x-3y=24...…….(2)

To solve these equations we add equation 1 and 2,

2x+3y+7x-3y = 3+24

9x = 27

Divide by 9 on both side, we get

x = 3

Now putting the value of x in equation 1, we get

2(3) + 3y = 3

6 + 3y = 3

Subtract 6 on both side, we get

3y = -3

Divide by 3 on both side, we get

Explanation:

Add up the three sides. Set the sum equal to the perimeter 36 so we can solve for x.

AB+BC+AC = perimeter

(4x+2)+(5x-3)+(2x+4) = 36

11x+3 = 36

11x = 36-3

11x = 33

x = 33/11

x = 3

Then use this x value to determine each side length.

The sides are

As a check so far: 14+12+10 = 36 which helps confirm we have the correct x value, and correct side lengths.

So first, you want to have one of the variables able to cancel out when you add the equations together.

To do this, divide the second equation by two

2x+2y=4

x+y=2

Next, get the variables on the same side on the both equations, so the second thing you do is add x to both sides on the top equation

y=-x+3

+x +x

y+x=3

Now you times one of them by -1 so a variable will cancle out.

y+x=3

x+y=2
