Hint:
[tex](a^{m})^{n}=a^{m*n}[/tex]
Answer:
[tex]1/x[/tex]
Step-by-step explanation:
To simplify, work from the inside out.
We start with
[tex]\sqrt[4]{x^{3/4}}[/tex]
on the inside. And we can change the fourth root into a fractional exponent -- 1/4:
[tex](x^{\frac{3}{4})^{1/4}[/tex]
A power of a power means multiply the exponents, giving
[tex]x^{\frac{3}{4} * \frac{1}{4}} = x^{3/16}[/tex]
So now we have
[tex][(x^{3/16})^{-4/3}]^4[/tex]
From here, apply the "power of a power rule" again, working from the inside out.
[tex](x^{-12/48})^4[/tex]
[tex]x^{-48/48}[/tex]
[tex]x^{-1}[/tex]
or
[tex]1/x[/tex]

Reasoning The midpoint of AB is on the
y-axis, and AB is parallel to the x-axis. Point A
is located in Quadrant III. Which quadrant
contains point B? Explain.
Answers
Answer:
B is in 4th quadrant.
Step-by-step explanation:
If mid point of AB is on x-axis then and A is in 3rd quadrant then B must be on the opposite side of A.Therefore it is in 4th
B is in fourth quadrant when AB is the midpoint on y axis
What is a quadrant with an example?An area enclosed by the x and y axes is known as a quadrant, and a graph has four of them.To clarify, the x and y axes divide the two-dimensional Cartesian plane into four quadrants.Quadrant I is in the upper right corner, while Quadrants II through IV are arranged from counterclockwise to clockwise.The x-axis (the horizontal number line) and the y-axis connect to divide the coordinate plane into four equal pieces in the cartesian system (the vertical number line).Due to the fact that each of these four areas takes up one-fourth of the entire coordinate plane, they are referred to as quadrants.If the center of AB is on the x-axis
A is in the third quadrant,
let two points ( -2, -2 ) in third quadrant .
then B must be on the side of A that is opposite from A.
B thus comes in fourth.
then points ( 2,-2 ) are in fourth quadrant .

What is the percentage change from 305 to 395
Answers
Answer:
29.51%
Step-by-step explanation:
The change from 305 to 395 is the difference between the two numbers. So, it would be 395 - 305 or 90. Now, to find the percentage of change, we need to find what part of the original amount is the change. In other words, we would have to divide 90 by 305. By putting this in a calculator you get about 0.2951. To convert this decimal into a percent, we would multiply by 100 giving us 29.51%.
A baker is building a rectangular solid box from cardboard to be able to safely deliver a birthday cake. The baker wants the volume of the delivery box to be 360 cubic inches. If the width of the delivery box is 3 inches longer than the length and the height is 4 inches longer than the length, what must the length of the delivery box be?
2 inches
5 inches
8 inches
9 inches
Answers
Answer:
5
Step-by-step explanation:
Solution is 8 in
Let´s call dimensions of the box
x the length of the boxy the width of the box andh the height of the boxAccording to the problem statement
y = x + 3 and h = 4 in
The volume of the box is:
V = x×y×h V = 360 in³
Then V = x × ( x + 3 ) × 4 ( by substitution of y as a function of x )
360 = x × ( x + 3 ) × 4
Simplifying by 4
90 = x × ( x + 3 )
90 = x² + 3x
We got a second degree equation, solving for x
x² + 3×x - 90 = 0
x₁,₂ = ( -3 ± √ (3)² + 4×90 )/2 ⇒ x₁,₂ = ( - 3 ± 19,21 )/2
x₁ ⇒ is a negative value x = - 11,1 so we dismiss such solution
x₂ = 16.21/2
x₂ = 8.1 in
rounding to the nearest integer number we get the value for the length f the box
x₂ = 8 in ⇒ x = 8 in

Answer:
d = 28.6 m
Step-by-step explanation:
Given:
vi = 22.4 m/s
vf = 0 m/s
t = 2.55 s
Find:
d = ??
d = (vi + vf)/2 *t
d = (22.4 m/s + 0 m/s)/2 *2.55 s
d = (11.2 m/s)*2.55 s
d = 28.6 m
If using the method of completing the square to solve the quadratic equation x^2+8x+37=0, which number would have to be added to "complete the square"?
Answers
Answer:
The numbers are --> x = -4 + √21 i and x = -4 — √21 i
See the attachment for my step-by-step explanation
(solution is in red box)
The number that would have to be added in the given quadratic equation to complete the square is '-21' and this can be determined by using the factorization method.

Answer:
Equation: [tex]3x-5+2x=90[/tex]
Angle measures: 52 degrees and 38 degrees
Step-by-step explanation:
Hi there!
We're given that the two angles form a right angle, which means they add up to 90 degrees.
Knowing this, we can construct the following equation:
[tex]3x-5+2x=90[/tex]
Now, we must solve for x:
[tex]5x-5=90\\5x=95\\x=19[/tex]
Therefore, x=19. Plug this into the expression for each angle to find their measures:
[tex]3x-5\\= 3(19)-5\\= 57-5\\=52[/tex]
[tex]2x\\=2(19)\\=38[/tex]
Therefore, the two angles measure 52 degrees and 38 degrees.
I hope this helps!
