If g(x) is the inverse of f(x), then by definition of inverse function,
f(g(x)) = g(f(x)) = x
Given that f(x) = 5x - 4, we have
f(g(x)) = 5 g(x) - 4 = x
Solve for g(x) :
5 g(x) - 4 = x
5 g(x) = x + 4
g(x) = (x + 4)/5

Find the area of the figure
Step-by-step explanation:
its a square from which a semi circle of radius of 3ft is cut

area of semi circle = π 9 ft^2
total area = 36 - 9π = 7.72 Ft^2
Which expression represents a number that is 4 times as great as the quotient of 25 and 5?
A. (25 x 5) x 4
B. 4 ÷ ( 25 ÷ 5 )
C. 4 x ( 25 ÷ 5 )
D. (25 ÷ 5 ) ÷ 4
Answer:
(25 ÷ 5 ) ÷ 4
Step-by-step explanation:
solve the equation for the variable. Then plug that variable value into the expression and simplify to get the answer.
Answer:
C
Step-by-step explanation:
the quotient of 25 and 5 is 25 ÷ 4 , then multiply this by 4 , so
4 × (25 ÷ 5 ) → C

The box-and-whisker plot below represents some data set. What is the range of the
data?
In order for the data in the table to represent a linear function with a rate of change of 5, what must be the value of a? a = 3 a = 8 a = 18 a = 33
To represent the linear function in order for the data the value of a=18.
What is a linear function?
In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
It is given that for a linear function the value is changing at the rate of 5 so we can see in the table as the function independent value is changing then the value of the dependent linear function increases by 5.
So the value of a will be equal to 18.To represent the linear function in order for the data the value of a=18.

what is the shaded part of the digestive (use 3. 14 as estimate for pi)
35 points for right answer
Answer:
Option A
Step-by-step explanation:
Area of shaded region
Square:
Side = 12 m
Area of square = Side *side
= 12 *12
= 144 square m
Circle:
diameter = side of the square
= 12 m
r = 12/2
r = 6 m
Area of circle = πr²
= 3.14 *6 * 6
= 113.04 m²
Area of the shaded part = area of square - area of circle
= 144 - 113.04
= 30.96 m²

Sandy has a ladder that is 16.5 ft long. He wants to lean the ladder against a vertical wall so that the top
the ladder is 15.9 ft above the ground. For safety reasons, he wants the angle the ladder makes with th
ground to be no greater than 76°. Will the ladder be safe at this height? Show your work and draw a diagram
to support your answer.
The ladder will be safe at this height .
What is trigonometric ratios?There are six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
According to question
Sandy has a ladder whose length = 16.5 feet
He wants to lean the ladder against a vertical wall 15.9 feet above the ground.
And he wants the angle the ladder makes with the
ground to be < 76°.
As Perpendicular = 15.9 feet
and Hypotenuse = 16.5
Sin Ф = [tex]\frac{Perpendicular }{Hypotenuse}[/tex]
Sin Ф = [tex]\frac{15.9}{16.5}[/tex]
Sin Ф = 0.9636
Therefore, Ф ≈ 74.49 (approx.)
That means it is safe .
Hence, The ladder will be safe at this height as it is not greater than 76° .

Quadrilateral KLMN has vertices K(-2,-2), L(1,1), M(0,4), and N(-3,5)
It is first translated by (x + 2,y - 1)
then
K(-2,-2) ---> K'(-2 + 2,-2 - 1) = (0,-3)
L(1,1), ---> L'(1 + 2,1 - 1) = (3,0)
M(0,4), ---> M' (0 + 2,4 - 1) = (2,3)

Alexander sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
8 visitors purchased no costume.
340 visitors purchased exactly one costume.
28 visitors purchased more than one costume.
If next week, he is expecting 600 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.
Answer:

Step-by-step explanation:
1) Add all of the origanal visitors (376)
2) Find the ratio (28/376) = 0.0744
3) Either 28/376 * 600 OR 0.0744 * 600 (I would recomend the fraction for more accurate answers, but because it says to round to the nearest whole number either will work, but you should still use fraction)
4) 44.6908

What is a monthly payment?The term loan refers to a sort of credit vehicle in which a sum of money is lent to another party in exchange for the value or principal amount being repaid in the future.
Then the formula of monthly payment (MP) will be
[tex]\rm MP = P \times \dfrac{r(1+r)^n}{(1+r)^n - 1}\\[/tex]
The formula can be written as
[tex]\rm P = MP \times \dfrac{(1+r)^n-1}{r(1+r)^n}\\[/tex]
You plan on supplementing your income. you would like to withdraw a semiannual salary of $6,951.20 from an account paying 1.75% interest, compounded semiannually.
The amount needed in the account is such that you can withdraw the needed amount at the end of each period for 15 years will be
MP = $6951.20
r = 0.00875
