hence we will get,

(g∘h)(x)=g(h(x))= g(x−1)= f(√x)= -1+√x =  √x -1

Now to find f(g(h(x))),

f(x)=x4+6  and g(h(x))=√x -1

Greta went to the salon and had 1/10 of an inch of hair cut off. The next day she went back and asked for another 1/2 of an inch to be cut off. How much hair did she have cut off in all? Write your answer as a fraction or as a whole or mixed number.

Answers

Answer:

3/5 of an inch

Step-by-step explanation:

Day 1:

Length cut off = 1/10 of an inch

Day 2:

Length cut off = 1/2 of an inch

How much hair did she have cut off in all?

Total hair cut off = Day 1 + Day 2

= (1/10 + 1/2) of an inch

= (1+5)/10

= 6/10

= 3/5 of an inch

She has to cut off 3/5 of an inch of hair in all

Find the length of leg a in a right triangle with leg b= 4 and hypotenuse C =5


Answers

Answer:

Leg A = 3

Step-by-step explanation:

You use the equation A squared plus B squared equals C squared. Then, you substitute the value that you have, so the equation would be a squared plus 3 squared equals 5 squared. Next, you square the two values to make the equation a squared plus 16 equals 25. After that, you subtract one of the values (which in case is 16) on both that leg value and the hypotenuse, so you are left with A squared equals 9. Finally, you square both 9 and A squared and you are left with A = 3. I hope that helps you understand it clearly!

In January of 2003, Jaylen deposited $1,450 into an investment account earning 5% interest, compounded semiannually. If there are no other deposits or withdrawals from the account, find the total interest earned by the end of December in 2017.

Answers

1450*1.05^30=$6266.816444
= my final answer is

=$6266.82

The amount generated at the end of December 2017 is [tex]\$ 3.04\times 10^{19}[/tex].

Compound Interest

The interest generated in a certain time interval on a particular sum is compounded with the principal sum to generate the interest for given time intervals is called the compound interest. The formula for the compound interest is given below.

[tex]A = p(1+\dfrac{r}{n})^{nt}[/tex]

Where A is the final amount, P is the initial principal sum, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods.

Given that the principal sum is $1,450, the interest rate is 5%, the time period is 15 years, the number of times interest applied per time period is 2(semiannually = twice in a year).

Hence the amount generated at the end of Dec 2017 is,

[tex]A = 1450 \times (1 + \dfrac {5}{2})^{2\times 15}[/tex]

[tex]A = 1450 \times 2.09\times 10^{16}\\ [/tex]

[tex]A = 3.04\times 10^{19}[/tex]

Hence we can conclude that the amount generated at the end of December 2017 is [tex]\$ 3.04\times 10^{19}[/tex].

Mr. Robert bought 17 dozen belts. He sold 196 of them at $9
each. For how much should he sell each of the remaining belts
if he wants to collect $1860 in sales?

Answers

Answer:

$12

Step-by-step explanation:

First, we calculate 196 x 9. Also, keep in mind that 17 dozen belts is 204 because of 17 x 12, so he needs to sell 8 more.

196 x 9 = 1,764.

Next, we subtract 1,764 from 1,860 to figure out the remainder.

1,860 - 1,764 = 96.

Then, we divide 96 by 8.

96 / 8 = 12.

He should sell each of the remaining belts at $12 each.

Answer:

$12 he should sell each belt for $12 each

Step-by-step explanation:

17 x 12 = 204

196 x 9 = 1764

1860 - 1764 = 96

204 - 196 = 8

8 x 12 = 96

What is linear inequality? What is the law of Reversal and law of Trichotomy? What is a mathematical equation and expression?Linear inequalities are defined as expressions in which two linear expressions are compared using the inequality symbols.y > mx + cy < mx + cy ≥ mx + cy ≤ mx + cReversal property : If (a > b) then (b < a) and  if (a < b) then (b > a).Law of Trichotomy : The "Law of Trichotomy" says that - only one of the following is true : (a < b) or (a = b) or (a > b).A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

The total cost =  $714

Step-by-step explanation:

Given

Monitor cost = $287Scanner cost = $58Keyboard cost = $49Printer cost = $320

The total cost can be determined by adding the costs of all the pieces of equipment.

Thus,

Total cost = Monitor cost + Scanner cost + Keyboard cost + Printer cost

                = $287 + $58 + $49 + $320

                = $714

Therefore, the total cost =  $714
