What is the expression in radical form?
Answer:
[tex]\sqrt[5]{25x^{2}y^{4}z^{6} }[/tex]
Step-by-step explanation:
going to the 2/5 power is the the fifth root of a square. For fraction exponents going into radical form use the denominator as you root of and use the numerator as the exponent of the rest making sure to multiply any other exponents by that number and when there is no exponent treat it as having an exponent of one for the multiplying.

Ally works in a shop for $18 per hour. She is not allowed to work more than 40 hours a week but has to work at least 20 hours. State a reasonable domain for this problem.
Answer:
Hi there!
The domain is:
20<=x<=40
Step-by-step explanation:
This states that:
x>=20
x<=40
Which fits the problem!
Hope this helps
For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.
Here we will find that the domain is D: [20h, 40h]
We know that Ally wins $18 per hour, and she has two restrictions:
She cant' work more than 40 hours.
She needs to work at least 20 hours.
Then her weekly salary can be written as:
s(x) = $18*x
Where x is the number of hours that she works each week.
With the above restrictions we have:
20h ≤ x ≤ 40h
Then the domain is:
D: [20h, 40h]

what is a compound interest
Answer:
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest

Step-by-step explanation:
Given the following functions f(x)
============================================
Work Shown:
[tex]g(x) = \frac{(x-1)^2}{3}\\\\g(f(x)) = \frac{(f(x)-1)^2}{3}\\\\g(f(x)) = \frac{(1+\sqrt{3x}-1)^2}{3}\\\\g(f(x)) = \frac{(\sqrt{3x})^2}{3}\\\\g(f(x)) = \frac{3x}{3}\\\\g(f(x)) = x\\\\[/tex]
The idea is to start with g(x) and then replace every x with f(x). From there you plug in f(x) = 1+sqrt(3x) and simplify.

How can you tell if there will be more than one solution for the geometric means? Why does this happen with the geometric means?
Answer:
a. We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.
b. This happens because, there are two possible values for the nth root of a set of even numbers.
Step-by-step explanation:
a. How can you tell if there will be more than one solution for the geometric means?
We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.
Since geometric means of n numbers from x₁,x₂, x₃,...,xₙ is
GM = ⁿ√x₁,x₂, x₃,...,xₙ .
Now, if n is an even number, the geometric means would have both a positive and negative value.
For example, if n = 2,
GM = ±√x₁,x₂ which is
GM = +√x₁,x₂ or -√x₁,x₂.
b. Why does this happen with the geometric means?
This happens because, there are two possible values for the nth root of a set of even numbers. For example if n = 2,
GM = ±√x₁,x₂ which is
GM = +√x₁,x₂ or -√x₁,x₂.
So, we have two possible values for the geometric means.

For each sequence, find the first 4 terms and the 10th term.
A) n+5
B)2n-1
Answer:
see explanation
Step-by-step explanation:
(a)
To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.
a₁ = 1 + 5 = 6
a₂ = 2 + 5 = 7
a₃ = 3 + 5 = 8
a₄ = 4 + 5 = 9
For the 10 th term substitute n = 10, that is
a₁₀ = 10 + 5 = 15
The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15
(b)
Substitute n = 1, 2, 3, 4 and 10 into the n th term formula
a₁ = 2(1) - 1 = 2 - 1 = 1
a₂ = 2(2) - 1 = 4 - 1 = 3
a₃ = 2(3) - 1 = 6 - 1 = 5
a₄ = 2(4) - 1 = 8 - 1 = 7
a₁₀ = 2(10) - 1 = 20 - 1 = 19
The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19

Each year, votes are cast for the rookie of the year in a softball league. The voting results for the top three finishers are shown in the table below. How many points is a third-place vote worth?
Answer:
A third place vote is worth 1 point
Step-by-step explanation:
Let the number of points for a first place vote be x, number of points for a second place vote be y and the number of points for a third place vote be z.
So, by multiplying the number of points by the number of what the point is worth and adding all together, we shall have the total points;
Hence, we have the following equation systems;
23x + 5y + z = 131
5x + 17y + 4z = 80
x + 5y + 15z = 35
These are the three equations we need to solve simultaneously to get the value of z
From equation 3, x = 35 -5y -15z
Insert this into the first two equations;
23 ( 35 -5y -15z) + 5y + z = 131
5(35-5y-15z) + 17y + 4z = 80
805 - 115y -345z + 5y + z = 131
805-131 = 115y + 345z -5y - z
674 = 110y + 344z ••••••••••(*)
The second equation now becomes the following;
5(35-5y-15z) + 17y + 4z = 80
175 -25y -75z + 17y + 4z = 80
175-80 = 25y + 75z -17y -4z
95 = 8y + 71z
8y + 71z = 95 •••••••••••(**)
So we have to solve x and xx simultaneously;
110y + 344z = 674
8y + 71z = 95
110/8 = 13.75 , so multiply equation xx by 13.75 and equation x by 1
110y + 344z = 674
110y + 976.25z = 1306.25
Subtract equation xx from x
(976.25z - 344z) = (1306.25 -674)
632.25z = 632.25
z = 632.25/632.25
z = 1
