Answer:
f⁻¹(x) =
Step-by-step explanation:
Given function,
→ f(x) = 5x - 6
We are supposed to find ths inverse of the given function. Consider the function, y = f(x).
→ y = 5x - 6
Add 6 to both sides.
→ y + 6 = 5x - 6 + 6
Solve the equation.
→ y + 6 = 5x
Division both sides by 5.
→ y + 6/5 = 5x/5
Solve the equation.
→ (y + 6)/5 = x
Can be re-written as,
→ x = (y + 6)/5
Now, recall f(x) = y, this implies x = f⁻¹(y).
→ f⁻¹(y) = (y + 6)/5
So the final answer is:
→ f⁻¹(x) = (x + 6)/5

What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that four friends, each bought matching necklaces and two pairs of earrings the necklace was priced at 15.00 if the total bill for all 4 friends was 128.00.
The cost of one pair of earing will be,
£128-£15-£15-£15-£15= £68
Number of pairs of earing,
2x4=8 pairs of earrings
The cost of one pair of earrings is,
£68 / 8 = £8.50

What is the median of the data set?
=========================================================
Explanation:
The diagram shows us we have this data set
{5, 8, 8, 8, 8, 9, 9, 9, 10, 10}
Cross off the outer most items (the 5 and the second 10) to get this smaller set
{8, 8, 8, 8, 9, 9, 9, 10}
Repeat the last step of crossing off the outer most items to get
{8, 8, 8, 9, 9, 9}
Keep this process going until we have this set of steps
{8, 8, 9, 9}
{8, 9}
We have two items left, which are tied for the middle, so we compute the midpoint
(8+9)/2 = 17/2 = 8.5 is the median
This is the middle most value
Which statement is most likely to be true? the ages of the mackerels are the most dispersed from the team’s mean. the ages of the stars are the most dispersed from the team’s mean. the ages of the dolphins are the most dispersed from the team’s mean. the ages of the giants are the most dispersed from the team’s mean.
The ages of the Stars are the most dispersed from the team’s mean
Which statement is right?Standard deviation is one way to measure the average of the data by determining the spread of the data. It actually explains how much the observation points are further away from the mean of the data.
Higher the standard deviation, higher the spread of the data and higher is the uncertainty. This means that the team with the highest standard deviation will have the most dispersion.
In this case, the standard deviation of 4.1 is the largest number, therefore, the statement "The ages of the Stars are the most dispersed from the team’s mean." is true

The base of a solid is bounded by x^2 + y^2 = 16. Cross sections perpendicular to the x-axis are right isosceles triangles with one leg located in the base. Which definite integral represents the volume of this solid?
The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.
x² + y² = 16 ⇒ y = ±√(16 - x²)
⇒ length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)
Cross sections with thickness ∆x have a volume of
1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x
since they are isosceles triangles and so their bases and heights are equal.
Then the total volume would be (D)
[tex]\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx[/tex]

The value of the z is −2.1 then the probability P(z < −2.1) is 0.0179. Then the correct option is A.
What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
If the value of the z is −2.1. Then the probability will be

Step-by-step explanation:
So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540
Then it is algebra
540=91+125+92+(3x-5)+(4x-8)
Simplify what you can and collect like terms
540=308+3x-5+4x-8
540=308+7x-13
Then move everything over to the one side so that the variable is isolated
540-308+13=7x
245=7x
242/7=x
35=x

Five roads form two triangles. What is the value of x? Justify your answer.
Using sine rule, the value of x in the triangle formed by five roads is 53.36 degrees.
How to find the angle of triangle using sine law?The value of x can be found using sine rule.
Therefore,
73.2 / sin 37° = 97.6 / sin x
cross multiply
73.2 sin x = 97.6 sin 37°
73.2 sin x = 97.6 × 0.60181502315
73.2 sin x = 58.7371462596
divide both sides by 73.2
sin x = 58.7371462596 / 73.2
x = sin⁻¹ 0.80242003086
x = 53.3618236772
x = 53.36°
Therefore, the value of x is 53.36°

Answer:
88 in³
Step-by-step explanation:
we are given that the volume V of a given mass of gas varies directly as the temperature T and inversely as the pressure P.
Condition-1:
The volume V of a given mass of gas varies directly as the temperature T , thus
[tex]V\propto T\\\implies V=kT[/tex]
Condition-1:
The volume V of a given mass of gas varies inversely as the pressure P, therefore,
[tex]V\propto 1/P\\\implies V=k\cdot 1/P[/tex]
combining 1 and 2 yields
[tex]V\propto k\cdot T/P[/tex]
Case-1:
V = 341.0 in³T = 310°P=10 lb/in²To find:
