What is the inverse of the function g(x)=x^3/8+16?
The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
What is inverse of the function?"The inverse function of a function f (also called the inverse of f ) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex]."
We have
[tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]
Replace g(x) with y
[tex]y =[/tex] [tex]\frac{x^{3} }{8}+16[/tex]
Interchange the variables
[tex]x= \frac{y^{3} }{8}+16[/tex]
Rewrite the equation as
[tex]\frac{y^{3} }{8}+16= x[/tex]
⇒[tex]\frac{y^{3} }{8}= x-16[/tex]
Multiply both sides of the equation by 8
[tex]8.\frac{y^{3} }{8}=8(x-16)[/tex]
⇒[tex]{y^{3} }=8(x-16)[/tex]
⇒[tex]{y^{3} }=8x-128[/tex]
⇒[tex]{y} }=\sqrt[3]{8x-128}[/tex]
⇒[tex]{y} }=2\sqrt[3]{x-6}[/tex]
Replace y with [tex]g^{-1}(x)[/tex]
⇒[tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
Hence, The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

Answer:
a) 0
b) -5
Step-by-step explanation:
We want to find f(x) = -4
This means find the value of x where y=-4
The value of x where y=-4 is x=0
Then find f(2)
This means find the value of y when x =2
The value of y when x=2 is -5

Card was bought for 5 dollars. It's has appreciated 5% each year. When will the card be worth 25 dollars?
Answer:
32 years
Step-by-step explanation:
Given data
Principal= $5
Rate= 5%
FInal amount= $25
Time=???
Applying the compound interest formula for time
t= ln(A/P)/r
t= ln(25/5)/0.05
t= ln(5)/0.05
t= 1.60/0.05
t= 35 years
Hence the time is 32 years

A clothing store conducts a survey to determine customer satisfaction.
Which of these methods will produce the most representative sample of the population of store customers?
A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C
C is your answer.

Dave and 6 friends went to dinner. They split the bill evenly. The total for the meal was $84. How much did each friend pay
Step-by-step explanation:
Dave + 6 friends = 7 friends in total
84 ÷ 7 = 12
Each friend paid $12
Each of them paid $12 for the Meal.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Dave and 6 friends went to dinner.
Total amount of meal= $84
So, each of them paid
= 84/ 7
= 12
Thus, each of them paid $12.

How to simplify the given expression?
Here we have the expression:
(-7x - 5) - (-9x^2 + 8x + 7)
To simplify it, we just perform the difference between the polynomials:
-7x - 5 + 9x^2 - 8x - 7
Now we group terms with correspondent powers of x:
9x^2 + (-7x - 8x) + (-5 - 7)

Step-by-step explanation:
Given
- 3 ≤ 5x + 2 ≤ 12 ( subtract 2 from each interval )
- 5 ≤ 5x ≤ 10 ( divide each interval by 5 )
- 1 ≤ x ≤ 2
Choose the function whose graph is given by:
O A. y= -0.5sin x
O B. y= cos X
Oc. y= 0.5cos x
OD. y= cos(2x)
(Ignore the answer selected I don’t know it it’s correct)
Using translation concepts, the function whose graph is plotted is given by:
y = 0.5cos(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the y-intercept is different of zero, hence it is a cosine function. The amplitude is of 0.5, hence the function is multiplied by 0.5, that is, y = 0.5cos(x), which means that option C is correct.

A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
if they started at a corner and walked diagonally to the other corner?
Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours

Write the quadratic equation in standard form.
Answer:
2x² + 6x + 15 = 0
Step-by-step explanation:
Given quadratic equation is,
-2x² - 6x = 15
We have to convert this equation in the standard form of the quadratic equation,
ax² + bx + c = 0
(-2x² - 6x) = 15
-2x² - 6x - 15 = 0
2x² + 6x + 15 = 0
An account earns simple interest. Find the annual interest rate. Interest = $60 principle = $500 time = 2 years Please help!!
Answer:
A = $560.00
Step-by-step explanation:
I = A - P = $60.00
Formula:
[tex]A = P(1 + rt)[/tex]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 500(1 + (0.06 × 2)) = 560
A = $560.00
The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.
