Answer:

(I attached an image of the graphed lines)

Step-by-step explanation:

First, we need to graph the original function:

The given equation is written in y=mx+b form, in which m is the slope and b is the y-intercept, or where the line crosses through the y axis. This means the slope is [tex]\frac{2}{1}[/tex] and the y-intercept is -4.

Next, we need to find the inverse of the function and graph that as well:

First, change f(x) in the given equation to y. These mean the same thing, it just makes it easier to work with.Swap the places of x and y. Then, the rest of the steps are essentially just isolating the variable y.Add 4 to both sides of the equation to cancel out the -4 (You will end up with -2y = x + 4)Divide both sides of the equation by -2 to isolate y (You will end up with y = (x/2) + 2)

Ou are a manager at Jimmy John's and have timed how fast your employees make a sandwich. Their times in seconds are below. Create a histogramto represent the data. 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9

Answers

Answer:

See attachment for histogram

Step-by-step explanation:

Given

[tex]Data: 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9[/tex]

Required

Represent on histogram

Calculate the range of the data

[tex]Range = 32.9 - 21[/tex]

[tex]Range = 11.9[/tex]

Using a width of 5, we have:

[tex]Class = \frac{Range}{5}[/tex]

[tex]Class = \frac{11.9}{5}[/tex]

[tex]Class =2.38[/tex]

Round up

[tex]Class = 3[/tex]

This means that the class will have 3 classes which are:

21.0 - 24.9, 25.0 - 29.9  and 30.0 - 34.9

The frequency table is as follows:

[tex]\begin{array}{cc}{Interval} & {Frequency}&{21.0 - 24.9} & {4} & {25.0 - 29.9} & {6} & {30.0 - 34.9} & {6} \ \end{array}[/tex]

Anthony makes candies for his party guests. First, he mixes 1 cup of cream with 2 cups of chocolate. In all, he uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?

Answers

Answer:

Cream = 3 cups

Chocolate = 6 cups

Step-by-step explanation:

Cream = 1 cup

Chocolate = 2 cups

Total = 3 cups

Cream : chocolate = 1 : 2

He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?

Cream = ratio of cream/total ratio of total cups

= 1/3 of 9

= 1/3 × 9

= 3 cups

Cream = 3 cups

Chocolate = ratio of chocolate/total ratio of total cups

= 2/3 of 9

= 2/3 × 9

= 6 cups

Chocolate = 6 cups

What is the explicit formula the sequence 8,10,12.5,15.625...?

Answers

Given:

The sequence is 8, 10, 12.5, 15.625,...

To find:

The explicit formula for the given sequence.

Solution:

We have,

8, 10, 12.5, 15.625,...

Here, the first terms is 8.

[tex]\dfrac{10}{8}=1.25[/tex]

[tex]\dfrac{12.5}{10}=1.25[/tex]

[tex]\dfrac{15.625}{12.5}=1.25[/tex]

The common ratio is 1.25. So, the given sequence is a geometric sequence.

The explicit formula for a geometric sequence is:

[tex]a_n=ar^{n-1}[/tex]

Where, a is the first term and r is the common ratio.

The explicit formula for the given geometric sequence is:

[tex]a_n=8(1.25)^{n-1}[/tex]

Therefore, the correct option is A.
