Answer:

see below

Step-by-step explanation:

The functions for these tables are, respectively, ...

f(x) = 5 - x

f(x) = 3x

f(x) = (x -1)² . . . . . a quadratic relation

f(x) = 4x² . . . . . . a quadratic relation

We assume the intention is that the terminology "quadratic variation" mean "proportional to the square of x". In that case, only the last function has such variation.

Sam studied guinea pigs for his science fair project. He found that the amount of weight the guinea pigs gained varied directly

Oliga [24]

From the given above, we can formulate the equation:

W = C / 218

By substituting the given values:

W = 1090 calories / (218 calories / 1 ounce)

W = 5 ounce

<span>Therefore the guinea pigs will gain additional 5 ounce if the diet was increased by 1090 calories.</span>

I am looking to decrease my bill by 25%. Can you look at my current plan and tell me what I can remove to achieve this reduction

Gennadij [26K]

Answer: $35

Step-by-step explanation:

From the question, we are informed that the current bill of the person is $140.00 per month and that the person wants to decrease the bill by 25%.

To know the amount that the person needs to deduct, we have to calculate 25% of $140.00. This will be:

= 25% of $140

= 25/100 × $140

= 1/4 × $140

= 0.25 × $140

= $35

The person will need to remove $35. The person will now pay ($140 - $35) = $105 monthly.

Explain how to find surface area of a rectangular prism. Be specific and use examples.

Leya [2.2K]

As you can see in the picture above, there are six faces of a rectangular prism; two are formed with dimensions width and height, two are formed by the dimensions length and width, and two are formed by the dimensions length and height. So, if you know the length, width, and height of the rectangular prism, then the formula for the surface area is

=(2⋅ℎ⋅ℎ)+(2⋅ℎ⋅ℎℎ)+(2⋅ℎ⋅ℎℎ)
