Answer:

A bit of a doosy, but bare with me: f*g*h(x) = [tex]x^2+54x-12x\sqrt{x} -108\sqrt{x} +90[/tex]

Step-by-step explanation:

So explaining this is a bit awkward as well, but I can try...So

Starting from g(x) working that backwards into f(x), so...

g(x) = [tex]x-3[/tex]

f(x) = [tex](x^4+9)[/tex]

Take your g(x) and plug it into your f(x) into every x you see

f(g(x)) = [tex](x-3)^4+9[/tex] ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...

Now you still have one more step which you still need to include h(x), so

Remember h(x) = [tex]\sqrt{x}[/tex]

Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

[tex](\sqrt{x} -3)^4 + 9[/tex]

Answer:

50% of the applicants will be hired.

Step-by-step explanation:

Given that four people applied for a job as an assistant manager at a store, but only two of these people will be hired, the following calculation must be performed to determine the percentage of people who will enter the job:

4 - 2 = 2

4 = 100

2 = X

2 x 100/4 = X

200/4 = X

50 = X

Thus, 50% of the applicants will enter the job.

Step-by-step explanation:

first you distribute

12x - 8 + 4 +23 +2x

than you add the numbers without the variable so...

-8+4+23= 19

Add the # with variables

12x+2x= 14×

then you get

14x=19

divide by 14 in each side

x=1.4

Answer:

The value of [tex]x[/tex] is 16.667.

Step-by-step explanation:

In this exercise, we know that the two triangles described in the figure are similar. If both are similar, the following ratio is constructed:

[tex]\frac{x}{25} = \frac{26}{39}[/tex] (1)

[tex]x = 16.667[/tex]

The value of [tex]x[/tex] is 16.667.

Step-by-step explanation:

They're still corresponding angles... have you read any of these explanations?...

Answer:

the book has 40 pages

Step-by-step explanation:

so he has read 90 percent and has 4 pages left. So 10 percent is 4 pages.

10 times 10 is 100. 4 times 10 is 40. The entire book is 40 pages.

10 percent equals 4 pages

20 percent percent 8 pages

30 percent  is 12 pages

40 percent is 16 pages

50 percent is 20 pages

60 percent is 24 pages

70 percent is 28 pages

80 percent is 32 pages

90 percent is 36 pages

100 percent is 40 pages

Answer:

kk so imma help you with this because this is like reealllyy easy soo basically all you have to do is use the multichoice and multiply is with the number example here is 2 then subtract/multiply/add/divide with the other number which is for this problem is 2. And right now our main goal is for it to equal 22 because both sides are equal. So if we multiplied 2 with 7 it would equal 14 and 14-2=12 which not be true. So you would have to the same thing for every one of the choices till it fits. And for this problem it would be 12 because 12x2=24 and 24-2=22. lol i hope you understand this whole thing annywwaaayyss hope this helped imma go finish my test now.

Answer:

2.75 minutes

Step-by-step

divide 55 by 20

Answer:

2.75 minutes/2 minutes and 45 seconds

Step-by-step explanation:

Divide: 55 divided by 20=2.75

2.75 minutes= 2 minutes and 45 seconds

The reason why you divide 55 divided by 20 is because you are trying to find how long it took you to clear 1 street.

And there are 20 streets and each street took you 2 minutes and 45 minutes to complete 1 street.

Hope this helped!! :)

Answer:

She should offer a guarantee of 13.76 years.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The average life of a certain type of small motor is 10 years with a standard deviation of 2 years.

This means that [tex]\mu = 10, \sigma = 2[/tex]

If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?

She should offer the 100 - 3 = 97th percentile as a guarantee, so X when Z has a pvalue of 0.97, that is, X when Z = 1.88.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.88 = \frac{X - 10}{2}[/tex]

[tex]X - 10 = 2*1.88[/tex]

[tex]X = 13.76[/tex]

She should offer a guarantee of 13.76 years.

=========================================================

Work Shown:

Let x = log(y+2)

The given equation becomes

4x = 3x-log(13)

Solving for x leads to

4x-3x = -log(13)

x = -log(13)

Then substituting gets us

log(y+2) = -log(13)

log(y+2) = log(13^(-1)) .... use the rule that A*log(B) = log(B^A)

log(y+2) = log(1/13)

y+2 = 1/13 ................. used the rule if log(A) = log(B), then A = B

y = (1/13) - 2

y = (1/13) - (26/13)

y = (1-26)/13

y = -25/13 .... answer is choice E

For each step, the logs are the same base. The base doesn't matter. It can be base 10 or base 2 or base e. As long as the base stays consistent is all that matters. Also, the base cannot be 1, 0 or a negative number. The base can be any other real number.

Answer:

The rate of change is 10%

Step-by-step explanation:

The computation of the rate of change is as follows:

Given that as on Jan 15, the snow pack is 150 inches

And, the last year, it would decrease by 11 inches a week after jan 15

So, the rate of change is

= 15 ÷ 150

= 10%

Step-by-step explanation:

Answer:

(-6, 6)

x=-6, y=6

Step-by-step explanation:

The easiest way to solve for this is by substitution. This means substituting y with -5x-24 in the first equation. It gives you the same variables and is easy to work with.

1. Set up your equation: -7x-4(-5x-24)=18

2. Use the distribution property: -7x+20x+96=18

3. Add like terms: 13x+96=18

4. Subtract 96 from both sides: 13x=-78

5. Divide by 13 to get x alone: x=-6

Now that we have x, we can find y much easier by plugging in -6 for x.

1. Set up your equation: -5(-6)-24=y

2. Multiply: 30-24=y

3. Subtract: 6=y

Check your answers!

-7(-6)-4(6)=18

-5(-6)-24=6

There you go! Hope this helped :)

Answer:

1/7

Step-by-step explanation:

1/3 of 3/7 = 1/3 x 3/7

we can cancel out 3 and 3 because they are multipliers of themselves

so now it is 1/1 x 1/7 = 1/7

Or .

1/3 x 3/7 = 1x3/3x7 = 3/21 = 1/7

Answer:

The guarantee should be made of [tex]X = 1.555 + 14\sigma[/tex] years, in which [tex]\sigma[/tex] is the standard deviation given in part (a).

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Assume that the average life of a refrigerator is 14 years

This means that [tex]\mu = 14[/tex]

The standard deviation given in part (a) before it breaks.

This will be the value of [tex]\sigma[/tex]

However, the company does not want to replace more than 6% of the refrigerators under guarantee. For how long should the guarantee be made?

We need to find the 100 - 6 = 94th percentile, which is X when Z has a pvalue of 0.94. So X when Z = 1.555. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.555 = \frac{X - 14}{\sigma}[/tex]

[tex]X = 1.555 + 14\sigma[/tex]

The guarantee should be made of [tex]X = 1.555 + 14\sigma[/tex] years, in which [tex]\sigma[/tex] is the standard deviation given in part (a).
