If f(x) =1/4x+14, then f^-1(x)=
Answer: f⁻¹(x)=4x-56
Step-by-step explanation:
f⁻¹(x) is the inverse of f(x). To find the inverse, we replace the y with x, and x with y. Once we do that, we solve for y.
[tex]x=\frac{1}{4}y+14[/tex] [subtract 14 on both sides]
[tex]x-14=\frac{1}{4}y[/tex] [multiply both sides by 4]
[tex]4(x-14)=y[/tex] [distribute 4]
[tex]4x-56=y[/tex]
[tex]f^-^1(x)=4x-56[/tex]

Carter graphs the equivalent ratios shown in the table. Yellow tiles 2 4 6 8 Red tiles 4 8 12 16 If one of the ordered pairs Carter graphs is (4, 2), which other ordered pairs does he graph? Check all that apply. (2, 4) (6, 12) (8, 4) (12, 16) (16, 8)
Answer:
The correct options are:
(8,4)
(16,8)
Step-by-step explanation:
The table is given which shows the number of yellow tiles and red tiles.
The first row in the table shows that if there are 4 red tiles then there will be 2 yellow tiles. This relation can be defined as the number of red tile will always be double the amount of number of yellows tiles. Carter graphs this point as (4,2) where number of red tiles are plotted on x axis and number of yellow tile are plotted on y axis.
Consider the second row of the table. Number of red tiles is 8 while number of yellow tiles is 4, so the point he plots on the graph is (8,4)
Similarly, other points are (12,6) and (16,8)
Answer:
It's (8, 4) and (16, 8)

Answer:
x° = 62
Step-by-step explanation:
The vertical angle to 28 degrees is 28 degrees in size.
The vertical angle to 90 degrees is 90 degrees in size.
Angles in a circle add up to 360 degrees.
x + 28 + 152 + 28 + 90 = 360
x + 298 = 360
x = 360 - 298
x = 62
Angle x is 62 degrees in size.

What is the probability of selecting a male from a group of 4
males and 8 females?
1
A 1/3
B 1/2
С 2/3
D 4/5
Answer:
[tex]P(Male) = \frac{1}{3}[/tex]
Step-by-step explanation:
Given
[tex]Male = 4[/tex]
[tex]Female = 8[/tex]
Required
Probability of selecting a male
First, we need to get the total population;
[tex]Total = Male + Female[/tex]
[tex]Total = 4 + 8[/tex]
[tex]Total = 12[/tex]
Let P(Male) represent Probability of Male
Let n(Male) represent number of Male
[tex]P(Male) = \frac{n(Male)}{Total}[/tex]
[tex]P(Male) = \frac{4}{12}[/tex]
Simplify fraction by dividing the numerator and denominator by 4
[tex]P(Male) = \frac{1}{3}[/tex]
Hence, the probability of selecting a male is 1/3
Suppose you want to simulate surveying 100 people to find the date of the month (1st, 2nd, 3rd, . . .) each was born. You decide to simulate the survey by having your computer randomly list values 1 through 31. Would the simulation provide a fair representation of an actual survey of 100 people? Why or why not?
No, because for the 12 months in the year not all of the dates are represented.
Yes, because it is possible to get 100 random values in a simulation.
Yes, because all possible dates of the month would be represented.
No, because for the 12 months in the year each date is not equally likely.
Answer:
D) "No, because for the 12 months in the year each date is not equally likely."
Step-by-step explanation:
For example, february does not have 31 days as well as april so it would not be a fair representation.

determine the perimeter and area of the Shaded portion of the figure below given the Circle diameter of 7 centimetre and the perimeter of the entire figure is 42 centimetre
Answer:
perimeter = 43.98cm
area = 76.96cm^2
Step-by-step explanation:
You take into account that the shaded regions are perfect circles, then, the total perimeter of the shaded regions are given by the circumference of both circles.
You calculate the circumferences, by using the following formula:
[tex]C=2\pi r[/tex] (1)
r: radio of the circles = (7/2)cm = 3.5cm
The total perimeter is twice the value of C in the expression (1). You replace r in (1), and calculate the total perimeter:
[tex]C=2\pi (3.5cm)=21.99cm\\\\C_T=2C=2(21.99cm)=43.98cm[/tex]
The perimeter of the shaded region is 43.98cm.
The area of the shaded region is twice the area of one of the circle, which is given by:
[tex]A=\pi r2=\pi (3.5cm)^2=38.48cm^2\\\\A_T=2A=2(38.48cm^2)=76.96cm^2[/tex]
The total area of the shaded region is 76.96cm^2

PLZ HELP, NEED ASAP Krista was assigned a homework problem that stated there were 45 stamps purchased for $18.75. Some stamps were 40 cents, and some stamps were 55 cents. To solve this problem, she wrote the system of equations that is shown below. 0.40 x + y = 45. x + 0.55 y = 18.75. Which explains the error that Krista made? Krista put 0.40 in the first equation meant for the number of stamps. Krista put 0.55 in the second equation meant for the value of stamps. Krista did not use the correct decimal to represent the total cost of the stamps. Krista mistakenly put 45 in the first equation when it should have been in the second equation.
Answer:
Krista put 0.40 in the first equation meant for the number of stamps.
Step-by-step explanation:
Krista's equation
0.40x+y=45
x+0.55y=18.75
The system of Equation should have been
x + y = 45 (1)
0.40x + 0.55y = 18.75 (2)
From (1)
x=45-y
Substitute x=45-y into (2)
0.40(45 - y) + 0.55y = 18.75
18 - 0.40y + 0.55y = 18.75
Collect like terms and you now have
0.55y - 0.40y = 18.75 - 18
0.15y = 0.75
Divide both sides of the equation by 0.15
y = 5
Substitute y=5 into (1)
x + y = 45
x+5=45
x=45-5
x=40
This shows that the stamps that cost 0.40 cents were 40 while those that cost 0.55 cents were 5 in number.
Krista's error:
Krista put 0.40 in the first equation meant for the number of stamps.
Answer: A, Krista put 0.40 in the first equation meant for the number of stamps.

if there are 54 in total, and 32 are women, that means 22 are men, we get this by subtracting 32 from 54 (54-32).
then if 18 of the 41 are male, who are right handed, subtract 18 from 41 (41-18) to get 23. that means there are 23 right handed women.
then we do 32-23 to get 9, this is how many left handed women there are.
then we do 22-18 which is 4. there are 4 left handed males

B) Point E
Step-by-step explanation:
There are 3 vowels in the word square, and there are six total letters in the word square.
Square
There is a half chance of picking a letter that is a vowel in the word "square". (Three is half of six.)
Point C would be the most accurate spot for question 'a'.
The word square does not have a 'T'. It is certain that a letter that is not 'T' would be picked.
Point E would be the most accurate spot for question 'b'.
Answer:
a) c b) e
Step-by-step explanation:
There are 3 vowels out of 6 total cards, and c lands at 3/6->1/2.
There is no letter T, so it is a 1/1 chance of not getting a T. E lands at 1.

Answer:
The height of the tree is 35.6 ft
Step-by-step explanation:
For this equation, we are going to use tan. We are using tan because we are given the side length for the adjacent side and we are looking for the side length of the opposite side which is also known as our tree's height.
Let's set up an equation.
[tex]tan45=\frac{x}{35.6}[/tex]
Since we do not know what the value of x is, then we are going to multiply 35.6 on both sides of the equation so we can get x by itself.
(35.6)tan45 = x/35.6 (35.6)
x = 35.6(tan45)
Now, we are going to multiply 35.6 by tan45. You can use a calculator when multiplying this one.
x = 35.6
The value of x is 35.6 which is also the height of our tree.

from rest, the car travels s inches in t seconds,
where s = 16t\t. Which of the following gives the
average speed of the car, in inches per second, over
the first t seconds after it starts?
Answer:
B) 16√t
Average speed of the car =16√t inches per second
Step-by-step explanation:
A) 4√t
B) 16√t
C) 16 / √t
D) 16t
Speed = distance / time
Distance = 16t√t
Time = t
Substitute the value of distance and time into the formula
Speed = distance / time
Speed = 16t√t / t
= 16√t
Therefore, speed = 16√t
Average speed of the car =16√t inches per second

8. In the diagram below, angle CAE = 39 °. Find the following
:) AOC
b) OBA
Answer:
a) 78°
b) 39°
Step-by-step explanation:
In circle with center O, DE is tangent at point A and AC is chord (or secant if extended both sides).
Therefore by tangent secant theorem.
[tex] m\angle CAE = \frac{1}{2} \times m\widehat{(AC)} \\\\
\therefore 39\degree = \frac{1}{2} \times m\widehat{(AC)} \\\\
\therefore m\widehat{(AC)} = 39\degree\times 2\\
\red{\bold{\therefore m\widehat{(AC)} = 78\degree}}\\[/tex]
Since, measure of central angle of a circle is equal to the measure of its corresponding minor arc.
[tex] \therefore m\angle AOC = m\widehat{(AC)}\\
\huge \purple {\boxed {\therefore m\angle AOC = 78\degree}} \\[/tex]
Next, by inscribed angle theorem:
[tex] m\angle CBA = \frac{1}{2}\times m\widehat{(AC)}\\\\
\therefore m\angle CBA = \frac{1}{2}\times 78\degree \\\\
\therefore m\angle CBA =39\degree \\\\
\huge \orange{\boxed {\therefore m\angle OBA = 39\degree}}\\... (\because C-O-B) \\[/tex]
