Part 3: Solve a real-world problem using a cube root function.
Once Isabel rented the warehouse space, she decided to post ads on several social media sites to advertise her online bookstore. Let x represent the number of months the ads have been posted. Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted.
f(x) = 1000 + 1000
⦁ How many books were sold after 8 months? (3 points)
⦁ Graph the function. (10 points)
Answers
Considering the given function, it is found that 3000 books were sold after eight months.
FunctionThe function in this problem is defined as follows:
f(x) = 1000(∛x) + 1000
In which f(x) represents the number of books sold after x months.
After eight months, we have that x = 8, hence the number of books is calculated as follows:
f(8) = 1000(∛8) + 1000
The lone instance of x in the function was replaced by eight to find the numeric value.
The cube root of eight is calculated as follows:
8 = 2 x 2 x 2 = 2³
Hence:
∛8 = 2
Thus the numeric value of the expression is:
f(8) = 1000(∛8) + 1000 = 1000 x 2 + 1000 = 2000 + 1000 = 3000 books.
The graph of the situation is given by the image at the end of the answer, at a domain of x >= 0, as the number of months cannot assume negative values.

QuestRecently, More Money 4U offered an annuity that pays 6.6% compounded monthly. If $1,504 is deposited into this annuity every month, how much is in the account after 11 years? How much of this is interest?Type the amount in the account: $(Round to the nearest dollar.)
Answers
ANSWER
Amount = $3102.75
Interest = $1598.75
EXPLANATION
The annuity pays 6.6% compounded monthly.
The formula for an Amount compounded at a rate of r after t years is given as:
[tex]A\text{ = P(1 + }\frac{r}{n})^{nt}[/tex]where P = principal (amount deposited) = $1,504
r = rate = 6.6% = 0.066
n = 12 (12 months in a year)
t = number of years = 11 years
Therefore, the amount in the account after 11 years is:
[tex]A\text{ = 1504(1 +}\frac{0.066}{12})^{12\cdot\text{ 11}}[/tex][tex]\begin{gathered} A=1504(1+0.0055)^{132} \\ A\text{ = 1504(}1.0055)^{132} \\ A\text{ = 1504 }\cdot\text{ 2.063} \\ A\text{ = \$3102.75} \end{gathered}[/tex]That's the amount in the account after 11 years.
This means that the amount of interest after 11 years is the amount after 11 years minus the amount that was there initially:
Interest = 3102.75 - 1504
Interest = $1598.75

3² +4² + 12² is equal to n² for some positive number n . Find n.
Answers
Answer:
n = 13
Step-by-step explanation:
For this, you need to square all of the numbers and then add them together. Most of the time, you can put them into a calculator but I will work it out below.
Squaring means multiplying a number by itself, so we get:
3² + 4² +12² =n²
Turns into:
(3*3) + (4*4) +(12*12) = n²
Then work out the multiplication:
9 + 16 + 144 = n²
Add everything together
169 = n²
Now take the square root of each side:
[tex]\sqrt{169} =\sqrt{n^{2}}[/tex]
This comes out to be:
± 13 = n
The question asks for the positive number, so you answer is:
n = 13
Which of the following is an example of the associative property of multiplication?7 . (3 . 5) = (7 . 3) . 507. (3+5) = 21 + 357.(3.5) = 7 . (5. 3)0.1=1
Answers
The associative property of multiplication states that you can choose any pair of numbers to multiply first when there are more than two numbers being multiplied. This doesn't change the final result:
a . b . c = (a . b) . c = a . (b . c)
So, we see an example of such property in the first option:
7 . (3 . 5) = (7 . 3) . 5
Let's check this is indeed true:
7 . (3 . 5) = 7 . 15 = 105
(7 . 3) . 5 = 21 * 5 = 105
Therefore, the first option is correct.
Notice that the second option uses the distributive property of multiplication over addition:
a . (b + c) = a . b + a . c
The third uses the commutative property of multiplication:
a . b = b . a
The fourth is wrong since zero multiplied by any number is zero, not one:
0 . a = 0, for all values of a.

There are two numbers whose sum is 50. Three times the first is 5 more than twice the second. What are the numbers?
Answers
The two numbers whose sum is 50 and three times the first is 5 more than twice the second are 21 and 29.
What do you mean by sum?
A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There could be only two terms, or there could be one hundred, thousand, or a million. There are summations with an infinite number of terms.
Let the two numbers be X and Y.
There are two condition given in the question through which we can form a system of equation containing two equations.
First condition: The sum of the numbers is 50.
Therefore,
X + Y = 50
Second Condition: Three times the first is 5 more than twice the second
Therefore,
3X = 2Y + 5
We get the system of equation:
X + Y = 50
3X = 2Y + 5
Solving this system of equation
3X - 5 = 2(50 - X)
3X - 5 = 100 - 2X
X = 105/5
X = 21
Putting the value of X in one of the equation:
Y = 50 - X
Y = 50 - 21
Y = 29
Therefore, two numbers are 21 and 29

Answers
The inequality that will calculate the number of yards (y) you will have to mow to get to at least the cost (C) of the car is 25y + 750 ≥ C.
If the car costs a total of $4500 number of yards you will have to mow is 150 yards at least.
What is inequality in math?In mathematics, a statement of an order relationship between two integers or algebraic expressions (greater than, greater than or equal to, less than, or less than or equal to) is called an Inequality.
Given:
Price of the car paid by your parents = $750
You have a summer job mowing yards for $25 per yard.
We have to determine an inequality that will calculate the number of yards (y) you will have to mow to get to at least the cost (C) of the car.
So, the required inequality is
25y + 750 ≥ C
Now, the Cost of the car given is $4500.
Substituting this in the inequality to find the number of yards,
25y + 750 ≥ 4500
Subtracting 750 from both sides
25y ≥ 3750
Dividing both sides by 25,
y ≥ 150
