Answer:
Step 1, all the exponents are increased by 4Step-by-step explanation:
The three steps are
(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = x²×y⁸/y⁴×x⁸×x⁸×y² =x²×y⁸/y⁶×x¹⁶Correct solution should be:
(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = all powers inside the parenthesis should be multiplied by 4 as per power of the power (xᵃ)ᵇ = xᵃᵇThis would give next steps:
x⁻⁸×y¹⁶/y⁴×x⁸×x⁸×y⁻⁸ =x⁻⁸×y¹⁶/x¹⁶×y⁻⁴ =y²⁰/x²⁴Answer options:
Step 1, all the exponents are increased by 4
There should be multiplication of powers. (It is close option but is not fully correct as not all the exponents increased by 4, for example y became y⁴)Step 2, the exponents of the same base are added during multiplication
It was done correctlyStep 3 wasn't performed yet, there was step 1 and 2.

It would be number 3.
Step-by-step explanation:
Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a sting of light around. what length of lights should he buy?
Answer:
78 feet
Step-by-step explanation:
assuming it's the perimeter
25 + 25 + 14 + 14 = 78
The length of the string of the lights is 78 feet.
What is the perimeter of the rectangle?P = 2(l + w), where 'l' is the length of the rectangle and w is the width of the rectangle
For given example,
Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a string of light around.
The length of the string of the lights = the perimeter of the rectangular wooden deck
Here, length of the deck (l) = 25 ft.
width of the deck (w) = 14 ft.
Using the formula of the perimeter of the rectangle,
⇒ P = 2 × (l + w)
⇒ P = 2 × (25 + 14)
⇒ P = 2 × 39
⇒ P = 78 ft.
The perimeter of the rectangular wooden deck is 78 feet.
Therefore, the length of the string of the lights is 78 feet.

Answer:
VA
Step-by-step explanation:
Angle VYA = 180-94-46 = 40 degrees.
Know that the side length opposite the smallest angle has the smallest length.
VY and VA are the two smallest, but 40 < 46, therefore VA is the shortest length.
Short (and not very rigorous) proof:
The law of sines says that sinA/a = sinB/b = sinC/c, where x is the side opposite the angle X
sin46/YV = sin40/VA
sin46 > sin40, therefore YV > VA.

(3×10^2 )×(2×10^−4 )=
Answer:
Step-by-step explanation:
First, lets simplify everything in the parenthesis.
(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:
6*10^-2

A group of friends wants to go to the amusement park. They have $94.25 to spend on parking and admission. Parking is $14.75, and tickets cost $13.25 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answer: 6
Step-by-step explanation:
From the question, we are informed that a group of friends wants to go to the amusement park and that they have $94.25 to spend on parking and admission.
We are further told that Parking is $14.75, and tickets cost $13.25 per person, including tax. The equation that can be used to solve the number of people who can go to the amusement park would be:
= 14.75 + 13.25p
Since they've $94.25 to spend, the number of people that can go to the amusement park will be:
14.75 + 13.25p = 94.25
13.25p = 94.25 - 14.75
13.25p = 79.50
p = 79.50 / 13.25
p = 6
6 people can go to the amusement park

Answer:
18750
Step-by-step explanation:
The recursive relation describes a geometric sequence with a first term of 6 and a common ratio of 5. The general term will be ...
an = 6·5^(n -1)
So, the 6th term will be ...
a6 = 6·5^(6-1) = 6·3125
a6 = 18750

Answer:
[tex]\frac{4}{3x-4}[/tex]
Step-by-step explanation:
The first thing we do to solve this is factor is completley
You can factor out a 4 from the numerator and get
4(3x+4)
The denominator is a difference of squares which means that
(x^2-y^2)=(x-y)(x+y)
which means that 9x^2-16=
(3x-4)(3x+4)
Put these together and get
[tex]\frac{4(3x+4)}{(3x-4)*(3x+4)}[/tex]
The 3x+4 cancels out and we get left with
[tex]\frac{4}{3x-4}[/tex]

(0, 20)
Step-by-step explanation:
You can plug any numbers in for x, and solve for y.
Example: 4(-2) + y =20 multiply 4 and -2
-8 + y = 20 add 8 to both sides
y = 28
You can then do this for the rest of the numbers. Here is a table below:
