7. Find the inverse of f(x) = 4x^3 + 8.
Answers
Answer:
The inverse of [tex]\displaystyle{f(x)=4x^3+8}[/tex] is determined to be [tex]{f^{-1}(x)=\sqrt[3]{\frac{1}{4}x-8}[/tex].
Step-by-step explanation:
In order to find the inverse of a function, we need to know a couple of rules about functions.
f(x) = yTo find the inverse, we flip the y-variable with the x-variables and solve for y.Following these rules, our function now becomes [tex]\displaystyle{x=4y^3+8}[/tex].
We now can simplify it further in order to find the value of x.
[tex]\displaystyle{x=4y^3+8}\\\\4y^3=x-8\\\\y^3=\frac{x}{4}-8\\\\\sqrt[3]{y^3}=\sqrt[3]{\frac{x}{4}-8} \\\\y = \sqrt[3]{\frac{1}{4}x-8}\\\\f^{-1}(x)= \sqrt[3]{\frac{1}{4}x-8}[/tex]
Therefore, the inverse of [tex]\displaystyle{f(x)=4x^3+8}[/tex] is [tex]\displaystyle{f^{-1}(x)=\sqrt[3]{\frac{1}{4}x-8}[/tex].
Answer:
[tex]\huge\boxed{f^{-1}(x) = \sqrt[3]{\frac{x-8}{4}}}[/tex]
Step-by-step explanation:
In order to find the inverse of a function, we need to follow a series of steps.
1. Write the function in the form [tex]y=ax^b+c[/tex]
2. Swap where the x and y values are
3. Solve for y
4. Convert into [tex]f^{-1}(x)[/tex] form
So first, we can write [tex]f(x)=4x^3+8[/tex] as [tex]y=4x^3+8[/tex].
Now we need to swap where the x and y variables are. This makes our equation [tex]x=4y^3+8[/tex].
To find the inverse, we now need to solve for y in this equation.
[tex]x=4y^3+8[/tex] Subtract 8 from both sides:[tex]x-8 = 4y^3[/tex] [tex]4y^3 = x-8[/tex] Divide both sides by 4:[tex]y^3 = \frac{x-8}{4}[/tex] Take the cube root of each side: [tex]y = \sqrt[3]{\frac{x-8}{4}}[/tex] Convert into [tex]f^{-1}(x)[/tex] form [tex]f^{-1}(x) = \sqrt[3]{\frac{x-8}{4}}[/tex]Therefore, the inverse of this function is [tex]f^{-1}(x) = \sqrt[3]{\frac{x-8}{4}}[/tex].

Omar has a gift card for $25 at a clothing store. He wants to buy socks that cost $4 per pair. He also has a coupon for $5 off his entire purchase. Omar wants to know how many pairs of socks he can buy. Write and inequality that represents the situation.
Answers
Answer:
4x ≤ 30
Step-by-step explanation:
Omar gets 30 dollars off because $25 + $5 = 30. Let x = pairs of socks
We know each pair costs $4, so the cost would be 4x. Omar has to buy as many pairs as he can with only the coupon and gift card. Omar has to spend $30 (the full discount) or less than $30. Therefore, the inequality would be: 4x ≤ 30 or 4x is less than or equal to 30 ($30).

A gallon of gas costs $2.73. Walter pays for 24 gallons of gas. He gives the clerk $80.00. How much change should Walter receive after paying for the gas?
Answers
step by step explanation:
you’d multiply 2.73 by 24;
2.73 x 24= 65.52
then you would subtract $80 and 65.52
when you subtract the answer you get is $14.48
hope this helps
He would pay $14.48
To get this answer you would need to multiply $2.73 by 24 and subtract by $80.

Aubrey’s monthly bank statement shows a total of $51 in fees for ATM withdrawals. If Audrey made 17 withdraws, what is Audrey charged for each withdrawal?
Answers
Answer:
Audrey was charged $3 for each withdrawal.
Step-by-step explanation:
We have to calculate the amount of money charged on one transaction.
In order to find the amount for one ATM withdrawal, the total amount for ATM withdrawals will be divided by number of withdrawals.
Given
[tex]Total\ ATM\ withdrawal\ fees = \$51\\Total\ withdrawals = 17\\Amount\ for\ one\ withdrawal = \frac{Total\ fees}{No.\ of\ withdrawals}\\= \frac{51}{17}\\= \$3[/tex]
Hence,
Audrey was charged $3 for each withdrawal.

Fred has $200. He wants to purchase a gym bag for $26 and as many pair of shoes as he can. Each pair of shoes is $45. What is the maximum number of pairs of shoes he can
purchase in addition to the gym bag?
Answers
Answer:
3 shoes
Step-by-step explanation:
You can set up an equation to solve this question like this:
200=45s+26
174=45s
174/45=s
s=3.867
You can't have a part of a shoe, so you have to round down to get 3 shoes
Answer:
3
Step-by-step explanation:
In order to get the answer to this question you subtract in till you can no longer subtract after subtracting the cost of the bag.
What we do know:
[tex]M=200[/tex]
[tex]B=26[/tex]
[tex]S=45[/tex]
[tex]200-26=174[/tex]
[tex]174-45=129[/tex]
[tex]129-45=84[/tex]
[tex]84-45=39[/tex]

An internet analytics company measured the number of people watching a video posted on a social media platform. The company found 129 people had watched the video and that the number of people who had watched it was increasing by 30% every 3 hours.
(a)
Write an exponential function for the number of people A who had watched the video n hours after the initial observation. (Enter a mathematical expression.)
Answers
Answer:
(a) The exponential function representing the number of people who had watched the video [tex]t[/tex] hours after the initial observation is [tex]n(t) = 129\cdot 1.3^{\frac{t}{3} }[/tex].
(b) As [tex]n(120) < 5\times 10^{6}[/tex], we conclude that this video is not going "viral".
Step-by-step explanation:
Statement is incomplete. The complete statement is:
An internet analytics company measured the number of people watching a video posted on a social media platform. The company found 129 people had watched the video and that the number of people who had watched it was increasing by 30% every 3 hours.
(a) Write an exponential function for the number of people A who had watched the video n hours after the initial observation.
(b) A video is said to go "viral" if the number of people who have watched the video exceeds 5 million within 5 days (120 hours). Would this video be considered to have gone viral?
(a) From the statement of the problem we get the following relationship:
[tex]\frac{n_{i+1}}{n_{i}}= r^{[(i+1)-i]}[/tex] (Eq. 1)
Where:
[tex]n_{i}[/tex] - i-th number of people watching a video, dimensionless.
[tex]n_{i+1}[/tex] - (i+1)-th number of people watching a video, dimensionless.
[tex]r[/tex] - Increase ratio, dimensionless.
For Induction Theorem, we get the following relatioship for [tex]i = 0[/tex]:
[tex]\frac{n_{1}}{n_{o}} = r^{1-0}[/tex] (Eq. 2)
For [tex]i = m[/tex], the following relationship is constructed:
[tex]\left(\frac{n_{1}}{n_{o}} \right)\cdot \left(\frac{n_{2}}{n_{1}} \right)\cdot ...\cdot \left(\frac{n_{m+1}}{n_{m}} \right) = r^{m}[/tex]
[tex]\frac{n_{m+1}}{n_{o}} = r^{m}[/tex](Eq. 3)
And for [tex]i = m+1[/tex], we have the following expression:
[tex]\left(\frac{n_{1}}{n_{0}} \right)\cdot \left(\frac{n_{2}}{n_{1}} \right)\cdot ...\cdot \left(\frac{n_{m+2}}{n_{m}} \right) = r^{m+1}[/tex]
[tex]\frac{n_{m+2}}{n_{0}} = r^{m+1}[/tex](Eq. 4)
If we multiply (Eq. 3) by the (m+1)-th ratio based on (Eq. 1):
[tex]\left(\frac{n_{m+1}}{n_{o}}\right)\cdot \left(\frac{n_{m+2}}{n_{m+1}} \right) = r^{m} \cdot r[/tex]
[tex]\frac{n_{m+2}}{n_{o}} = r^{m+1}[/tex]
Which is (Eq. 4) and the exponential function is represented by:
[tex]n_{i+1} = n_{o}\cdot r^{i}[/tex], [tex]i\in \mathbb{N}_{O}[/tex] (Eq. 5)
As the number of people is increased at constant rate every 3 hours, we get that [tex]i[/tex] is:
[tex]i = \frac{t}{3}[/tex], [tex]t \in \mathbb{R}[/tex], [tex]t \geq 0[/tex] (Eq. 6)
Where [tex]t[/tex] is the time, measured in hours.
Then, the exponential function is:
[tex]n(t) = n_{o}\cdot r^{\frac{t}{3} }[/tex] (Eq. 7)
Where [tex]n_{o}[/tex] is the initial number of people watching the video, dimensionless.
If we know that [tex]n_{o} = 129[/tex] and [tex]r = 1.3[/tex], then the exponential function representing the number of people who had watched the video [tex]t[/tex] hours after the initial observation is:
[tex]n(t) = 129\cdot 1.3^{\frac{t}{3} }[/tex]
(b) If we know that [tex]t = 120\,h[/tex], then we evaluate the exponential function:
[tex]n (120) = 129\cdot 1.3^{\frac{120}{3} }[/tex]
[tex]n(120) = 4.659\times 10^{6}[/tex]
As [tex]n(120) < 5\times 10^{6}[/tex], we conclude that this video is not going "viral".
