Which function is the inverse of f(x) = 2/3 x³ + 1?
Answers
The inverse of f(x) = 2/3 x³ + 1 is f^-1(x) = (3/2)(x-1)^(1/3).
Which function is the inverse of f(x) = 2/3 x³ + 1?The inverse of a function f(x) is a function that reverses the operation of the original function.The inverse of a function f(x) = 2/3 x³ + 1 can be found by switching the x and y values and then solving for x.In other words, we can set y equal to the original equation and solve for x.
Let y = 2/3 x³ + 1
We can then subtract 1 from both sides to get y – 1 = 2/3 x³
We can then divide both sides by 2/3 to get (y – 1) • (3/2) = x³
Finally, we can take the cube root of both sides to get the inverse function:
x = (y – 1)¹/₃ • (3/2)¹/₃
Therefore, the inverse of f(x) = 2/3 x³ + 1 is x = (y – 1)¹/₃ • (3/2)¹/₃.
The inverse of f(x) = 2/3 x³ + 1 is denoted as f^-1(x). To find the inverse, we need to solve for x in terms of y, since the inverse of a function is a reflection of the function across the line y = x. To do this, we need to rearrange the equation, so that x is on the left side of the equation. We can start by subtracting 1 from both sides.This yields 2/3x³ = y - 1. We can then divide both sides by 2/3 to get x³ = (y - 1)/2/3. To solve for x, take the cube root of both sides. This yields x = cube root[(y - 1)/2/3]. Therefore, the inverse of f(x) = 2/3 x³ + 1 is f^-1(x) = cube root[(y - 1)/2/3].To learn more about the inverse of a function refer to:

What does inequality really mean?
In mathematics, an inequality is a linear connection or a collection of numbers even when there is no equal sign. Equity always comes after equilibrium. When two numbers are not equal, inequality exists. Between equality and inequality, there exist differences. The most common symbol was chosen because when parameters aren't the same or comparable (). Values can be compared using a variety of disparities, no matter how few or numerous they are.

The circle with a 7 feet radius cut into 6 equal sectors, indicates, using 22/7 approximation for pi, that the area of 2 of the pieces is 51 and one third square feet. The correct option is option C.

What is a sector of a circle?A sector of a circle is a pie shaped part of a circle that is bounded by an arc and two radii of the circle.
The specified radius of the circle, r = 7 feet
The number of pieces to which the circle is cut into = 6 equal pieces (sectors)
The area of 2 of the pieces, using 22/7 as an approximation for π are found as follows;
Area of a circle, A = π × The square of the radius
Therefore; A = π × r²
A = (22/7) × 7² = 154
The area of the circle is about A = 154 square feet
The area of one of the pieces into which the circle is cut is therefore;
Area of a piece = A/6
Area of one piece = (154 square feet)/6 = 25 and two thirds square feet
The area of 2 of the pieces = 2 × (A/6) = A/3
Therefore, the area of two of the pieces = (154 square feet)/3 = 51 1/3

Dividing 4x³ + x² - 27x + 18 by 4x - 3 will result to a quotient of x² + x - 6 and a remainder of 0
Calculating for the quotient and remainderThe long division method will require us to; divide, multiply, subtract, bring down the next number and repeat the process to end at zero or arrive at a remainder.
We shall divide the 4x³ + x² - 27x + 18 by 4x - 3 as follows;
4x³ divided by 4x equals x²
4x - 3 multiplied by x² equals 4x³ - 3x²
subtract 4x³ - 3x² from 4x³ + x² - 27x + 18 will result to 4x² - 27x + 18
4x² divided by 4x equals x
4x - 3 multiplied by x equals 4x² - 3x
subtract 4x² - 3x from 4x² - 27x + 18 will result to - 24x + 18
-24x divided by 4x equals -6
4x - 3 multiplied by -6 equals - 24x + 18
subtract - 24x + 18 from - 24x + 18 will result to a remainder of 0
Therefore by the long division method, 4x³ + x² - 27x + 18 by 4x - 3 gives a quotient x² + x - 6 and a remainder of 0.

on a certain hot summers day 393 people used the piblic swimming pool the daily prices are $1.50 for children and $2.50 for adults the receipts for admission totaled $678.50 how many children and how many adults swam at the public pool that day
Answers
Answer: There were 304 children and 89 adults at the public pool on that hot summer day.
Step-by-step explanation:
Let's say the total number of people at the pool that day is x + y = 393
The total cost of admission for all the people is $678.50
The cost for each child's admission is $1.50 and the cost for each adult's admission is $2.50
We can use this information to set up two equations:
x + y = 393 (Total number of people)
1.5x + 2.5y = 678.5 (Total cost of admission)
Now we can use the first equation to solve for one of the variables. For example, we can solve for y:
y = 393 - x
We can substitute this value of y into the second equation:
1.5x + 2.5(393 - x) = 678.5
We can then solve this equation for x:
1.5x + 982.5 - 2.5x = 678.5
-x = -304
x = 304
This means that there were 304 children at the pool that day. We can use the first equation to find the number of adults:
x + y = 393
304 + y = 393
y = 393 - 304
y = 89
Therefore, there were 304 children and 89 adults at the public pool on that hot summer day.

Step-by-step explanation:
let t represent time, l represent length and n represent number of painters.
given t varies directly with l and inversely with n then the equation is
t = [tex]\frac{kl}{n}[/tex] ← k is the constant of variation
to find k use the condition t = 5 when l = 200 and n = 3 , then
5 = [tex]\frac{200k}{3}[/tex] ( multiply both sides by 3 )
15 = 200k ( divide both sides by 200 )

t = [tex]\frac{0.075l}{n}[/tex] ← equation of variation
when l = 500 and n = 5 , then

Answers
Triangle a is a shape that is formed by connecting three points.
What is triangle?Triangle is a geometric figure with three sides and three angles. It is one of the basic shapes in geometry. Triangles are either right, acute, or obtuse, depending on the size of each angle. The sum of the angles in a triangle is 180 degrees. Triangles can be classified into equilateral, isosceles, and scalene triangles, depending on the length of the sides. All three types of triangles have various applications in mathematics, physics and engineering.
In order to reflect triangle a in the x axis, triangle b must be a mirror image of triangle a. To achieve this, each point in triangle a must be reflected across the x axis. This is done by multiplying the y coordinate of each point in triangle a by -1. As a result, triangle b will have the same three points as triangle a, except that the y coordinates of each point in triangle b will be the opposite of what they are in triangle a.
After reflecting triangle a in the x axis to form triangle b, the next step is to rotate triangle b around the origin 90°. This can be achieved by finding the coordinates of each point in triangle b, then rotating each point around the origin. To do this, the x coordinates of each point in triangle b remain the same, while the y coordinates are multiplied by -1. As a result, triangle c will be formed as a 90° rotation of triangle b around the origin.

If you roll 2 dice, what is the probability that you will roll a seven (the numbers on the dice add up to a seven) on or before the 5th roll
Answers
Answer:
The probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%
Step-by-step explanation:
The probability of rolling a seven on any given roll of two dice is 1/6, since there are six ways to roll a seven (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) out of the 36 possible outcomes (1-6 on the first die and 1-6 on the second die).
To find the probability of rolling a seven on or before the 5th roll, we can use the cumulative probability formula which is the probability of getting a specific event on the first roll plus the probability of getting the event on the second roll plus the probability of getting the event on the third roll and so on.
So the probability of rolling a seven on or before the 5th roll is:
P(rolling a seven on the 1st roll) + P(rolling a seven on the 2nd roll) + P(rolling a seven on the 3rd roll) + P(rolling a seven on the 4th roll) + P(rolling a seven on the 5th roll)
= (1/6) + (1/6) + (1/6) + (1/6) + (1/6)
= 5/6
So the probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%
It's worth noting that this probability is independent of the previous outcomes of the rolls, so the probability of rolling a seven on or before the 5th roll stays the same even if you already rolled a seven in previous rolls.
