Answer:
[tex]x = 17[/tex].
Step-by-step explanation:
Simplify the given equation:
[tex]2\, (x - 1)^{3/4} = 16[/tex].
[tex](x - 1)^{3/4} = 8[/tex].
[tex]((x - 1)^{1/4})^{3} = 8[/tex].
Take the cubic root of both sides to eliminate the numerator of the exponent. Only roots of even degree could introduce alternative solutions. Since the degree of this root is an odd number, this step would not create extraneous solutions.
[tex]\sqrt[3]{((x - 1)^{1/4})^{3}} = \sqrt[3]{8}[/tex].
[tex](x - 1)^{1/4} = 2[/tex].
Raise both sides to the fourth power to eliminate the denominator of the exponent:
[tex](x - 1) = 2^{4}[/tex].
[tex]x - 1 = 16[/tex].
[tex]x = 17[/tex].
Substitute the solution [tex]x = 17[/tex] into the equation:
[tex]\begin{aligned}& 2\, (17 - 1)^{3/4} \\ =\; & 2\times (16^{1/4})^{3} \\ =\; & 2 \times 2^{3} \\ =\; & 16\end{aligned}[/tex].
Thus, [tex]x = 17[/tex] isn't an extraneous solution since setting [tex]x[/tex] to [tex]17[/tex] satisfies the original equation.

mai bought some party supplies from an online store.the shop charges a 7.95 shipping fee or 6.25%of the total purchase.whichever is greater.suppose Mai's total purchase is 128.how much shipping will she pay?
The required amount of shipping paid by Mai is 8.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now it is given that,
Amount of shipping fee = 7.95
percentage of shipping fee = 6.25% of the total purchase
Total amount purchased = 128
Thus, amount of shipping for this purchase is given as,
Amount of shipping = 6.25% of 128
Solving,
Amount of shipping = 0.0625*128 = 8
Since the shop charges shipping fees of whichever is greater
and 7.95 < 8
Thus, amount of shipping paid by Mai = 8
Thus, the required amount of shipping paid by Mai is 8.

Given the dimensions of the shape, the length of PR can be found to be 19.8 units.
How to find the length of PR?The given triangle is an equilateral triangle which means that all the sides are equal.
That then means that:
PR = QR
So we can solve as:
2n + 9 = 7n - 18
Solving for n gives:
7n - 2n = 18 + 9
5n = 27
n = 5.4
The length of PR is therefore:

I think the answer could be 7913.3
Step-by-step explanation:
Using clue number 2 we know that all the numbers in this are odd so that mean the only numbers that can be there are 1,3,5,7 and 9 Using clues 3 and 4 there are a few combinations some of which can be 1 + 1 + 3 = 5 , 1 + 1 + 7 = 9, 1 + 1 + 5 = 7, and 3 + 3 + 1 = 7 With clue 5 in being mentioned the dights in the ones place can't be 1 and 1 because it would equal one and any other dight besides it would be greater then that so I went with 3 and 3 as the tenths and ones dights since 3 × 3 = 9 and 1 being in the tenths place is less then 1The only other clue is clue 6 which means that the hundreds dights has to be a odd number greater than 7 and 9 is the only option that's greater than 7.

/A and /B are vertical angles. If mA = (4x − 4)° and m/B = (5x – 29)°,
-
then find the measure of /A.
the measure of angle A is 96° when A and B are vertical angles.
We are given the two vertical angles as:
A = (4x − 4)° and B = (5x – 29)°
We know that, vertical angles are equal to each other.
So, we get that:
4 x - 4 = 5 x - 29
5 x - 4 x = 29 - 4
x = 25
A = 4 x - 4
A = 4 ( 25 ) - 4
A = 100 - 4
A = 96°

Solve each equation. log₇(2 x-3)²=2
The solution of the given logarithmic equation is 16.189.
What are the various properties of the logarithm?
Out of several properties of logarithms, some of the main properties are given below:
Product Rule
log (ab) = log a + log b
Change of base
log ₇ x = log x / log 7
Power Rule
log a² = 2 log a
Quotient Rule
log (a / b) = log a - log b
Solving the given equation log₇(2x - 3)² = 2
We are given a logarithmic expression: log₇(2x - 3)² = 2
Using properties of the logarithm, we have
log (2x - 3)² / log 7 = 2
log (2x - 3)² = 2 × log 7
2 log (2x - 3) = 1.6901
log (2x - 3) = 3.3802
Using exponential on both sides,
e^[log (2x - 3)] = e^(3.3802)
2x - 3 = 29.3766
2x = 32.3766
x = 16.189

Etsuko practices origami. The square papers she used have a side length of either 7.5 cm or 25.4 cm. Etsuko says the length of the larger paper is 32.9 cm greater than the length of the smaller paper
To find how many centimeters greater the length of the larger paper is than the length of the smaller paper, the lesser number of centimeters needs to be subtracted from the greater number of centimeters which gives the result that is 17.9cm. Etsuko is incorrect because 25.4 is greater than 7.5cm.
How much greater is the side length of the paper?The mathematical operation that would be used to determine how much greater the larger paper is compared to the smaller paper is subtraction. Subtraction is the process used to determine the difference between two or more numbers. The sign that is used to represent subtraction is -.
To subtract the numbers, the length of the longer paper would be subtracted from the shorter paper.
Difference in the length of the papers = 25.4 - 7.5 = 17.9cm

What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the Coordinates.
The point is given as;
⇒ J (4, -4)
Now, The rule of the reflection of a point across the y-axis is equal to
(x, y) ⇒ (-x, y)
Hence, The coordinate of the resulting point J' after reflection over the y - axis of point J (4, -4) is,
(4, -4) ⇒ (-4, -4)
