Rewrite the expression using each base only once.
5^-13x5^5x2^5
The expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as 5⁻⁸ × 2⁵.
What is Exponentiation?Exponentiation is the method of writing a number in terms of powers. This method is usually useful for writing larger numbers in an understandable and effective way.
For a number x, suppose x can be written as aᵇ, here 'a' is called the base and 'b' is called the exponent.
We have to write the expression 5⁻¹³× 5⁵ × 2⁵ in a form where each base comes only once.
This can be solved using one of the basic property of exponents as stated below:
xᵃ × xᵇ = xᵃ⁺ᵇ
That is, upon multiplying two exponents with the same base value, we can combine it and add the exponent values.
∴ 5⁻¹³× 5⁵ can be rewritten as 5⁻⁸.
So 5⁻¹³× 5⁵ × 2⁵ = 5⁻⁸ × 2⁵.
Hence the expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as 5⁻⁸ × 2⁵ where each base comes only once.

D- According to the equation, how much could a person earn who works 40 hours?
E- What if the person got a $50 bonus and also worked some hours? How would this change the graph?
The linear equation is given by y = 15x. A person earns $600 for working 40 hours
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
The line passes through (7, 105) and (8, 120), hence:
y - 105 = [(120 - 105)/(8-7)}(x - 7)
y = 15x

Answer:
[tex]g(x) = 5x^2[/tex]
Step-by-step explanation:
In the equation x^2, when x = 1, y = 1. But in g(x), when x is 1, y is 5. Since g(x) is a scaled version of x^2, we can conclude that g(x) is 5 times x^2.
Therefore, [tex]g(x) = 5x^2[/tex].

Steven’s cat drinks water from a bowl. The following function represents the ounces of water left in the bowl in terms of hours since it was filled. y= -1/2x + 4 Which variable represents the number of hours since the bowl was filled
Considering the given linear function, variable x represents the number of hours since the bowl was filled.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the number of ounces of water left in the bown after x hours is given by:
y = -0.5x + 4.
Variable x is the input, hence, it represents the number of hours since the bowl was filled.
More can be learned about linear functions at https://brainly.com/question/24808124
Answer:
Part A: The number of ounces of water left in the bowl depends on the number of hours since the bowl was filled. So the number of ounces is the dependent quantity. The y-variable represents the dependent quantity. So, the y-variable represents the ounces of water left in the bowl.
Part B: The number of hours since the bowl was filled is the independent quantity. The x-variable represents an independent quantity. So, the x-variable represents the number of hours since the bowl was filled.
Part C: The value 4 is the initial value of the function. It represents the ounces of water in the bowl immediately after the bowl was filled and before the cat drank any water from the bowl.
Part D: The value -1/2 is the function’s rate of change. It represents the change in ounces of water in the bowl with every hour.

So we first split the shape so we get a triangle...
A=1/2bhB=2H=4A=1/2*2*4A=4Now we split the shape again to get another square...
A=lwA=2*4A=8Then we find the area of the other square...
A=lwA=2*5A=10Our last step is to add all the areas together
we let TA represent Total areaTA=4+8+10TA=22Hence the area is 22
Find the range of the quadratic function.
y= 3x2 – 18x+ 23
Write your answer as an inequality using x or y as appropriate.
Or, you may instead click on "Empty set" or "All reals" as the answer.
Answer:
-4 ≤ y <∞.
Step-by-step explanation:
y = 3x² - 18x + 23
= 3(x² - 6x) + 23
= 3(x² - 6x + 9) - 27 + 23
= 3(x - 3)² - 4 ≥ -4
So the range is -4 ≤ y <∞.

f(x)=^3 4x g(x)=2x+3 find(f/g) (x). Include any restrictions on the domain.
Answer:answer is b
Step-by-step explanation:
The value of function (f/g)(x) is 3√4x/2x+3 , where x ≠ -3/2.
What is Function?
A relation between a set of inputs having one output each is called a function.
The functions are given as;
f(x) = 3√4x
g(x) = 2x + 3
Now, We are to find the value of function (f/g)(x) as;
(f/g)(x) = f(x)/g(x)
(f/g)(x) = 3√4x/2x+3
Hence, The value of function (f/g)(x) is 3√4x/2x+3
And, Restriction of the function occurs at the point where the denominator is zero.
Hence,
2x + 3 = 0
2x = -3
x = -3/2
So, The required function (f/g)(x) is 3√4x/2x+3 , where x ≠ -3/2.
