-1/20 is simplified down to its lowest term or fraction therefore, this fraction is already simplified.

This fraction is already simplified in lowest terms so it cant go any further.

For the real-valued functions, find the composition and specify its domain using interval notation.

Helen [10]

Answer:

Composition: $f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1$

Domain = { $x\,/\,x\geq \,-4$ }

Step-by-step explanation:

Given

$f(x)=4\,x-1\,\,\, and \,\,\, h(x)=\sqrt{x+4}$

The requested composition becomes:

$f(x)\,^o\,h(x)=f(h(x))\\f(x)\,^o\,h(x)=f(\sqrt{x+4} )\\f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1$

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:

$x+4\geq \,0$ (so the square root is defined in the Real number system)

This means $x\geq \,-4$

The Domain is then all the Real x-values such that $x\geq \,-4$

Frank has a sheet of paper which is 1/624 inch thick. If the sheet is folded in half, the total thickness will be 1/312 inch A s

netineya [11]

Answer:

The thickness of the sheet will be 16/39 inch after folded 8 times

Step-by-step explanation:

* Lets explain how to solve the problem

- Frank has a sheet of paper of 1/624 inch thick

- The sheet is folded in half, the total thickness is 1/312 inch

- The sheet folded in half again and the total thickness is 1/156 inch

- We need to know the thickness of the sheet after folded 8 times

∵ The 1st thickness is 1/624 inches

∵ The 2nd thickness is 1/312 inch ⇒ after 1st fold

∵ The 3rd thickness is 1/156 inch⇒ after 2nd fold

∵ 1/312 ÷ 1/624 = 2

∵ 1/156 ÷ 1/312 = 2

∴ There is a common ratio 2 between each two fold

∴ The thicknesses of the sheet after each fold formed a

geometric series

∵ Any term of the geometric series is $a_{n}=a(r)^{n-1}$ , where

a is the first term, r is the ratio between each two consecutive

terms and n is the position of the term

∵ a = 1/312 because it is the thickness of the 1st fold

∵ r = 2 , n = 8

∴ $a_{8}=\frac{1}{312}(2)^{8-1}=\frac{16}{39}$

∴ The thickness of the sheet will be 16/39 inch after fold 8 times

Read the word problem below. Jill had $90. She bought a skirt that normally costs $42 but was on sale for half price. She also b

Likurg_2 [28]

Answer:

What was the regular price of the T-shirt?

What question is being asked in this word problem?

what is the regular cost of the t-shirt purchased by Jill.

What is the regular price of the skirt?

How much money does Jill have left?

without considering sales tax, Jill has $90 - $31 = $59 left.
If I use the sales tax from where I live, the sales tax = $1.86, so the money that Jill will have left = $59 - $1.86 = $57.14

How much does the T-shirt normally cost?

$18 (same as question 1)

What is the amount Jill pays in sales tax?

since you do not include the sales tax % in the question, I will simply use the sales tax from where I live = $31 x 6% = $1.86

Step-by-step explanation:

skirt $21

t-shirt = p - $8

before sales tax, total cost was $31

$21 + p - $8 = $31

p = $18
