The ratio x : y is 1 : 3
Which of the following statements are correct?
A) x is 1/3 of y
B) y is 3/4 of (x + y)
C) x is 1/4 of y
D) y is 3/4 of x
Answer:
A. x is ⅓ of y
Step-by-step explanation:
x : y
= 1 : 3
Therefore,
x = 1
y = 3
If so x is 1/3 of y

The function f is defined as follows for the domain given.
f(x) = 2–2x domain = (-1,0, 1, 2}
Write the range of f using set notation. Then graph f.
Answer:
The range of the function in ascending order is:
Range R = {-2, 0, 2, 4}
Step-by-step explanation:
Given the function
f(x) = 2-2x
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axisAs the domain of the function is given such as
Domain D = {-1, 0, 1, 2}
Determining the range
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.
As the domain is
Domain D = {-1, 0, 1, 2}
FOR x = 1
substitute x = -1 in the function
f(x) = 2-2x
f(-1) = 2-2(-1) = 2+2=4
so
at x = -1, y = 4
FOR x = 0
substitute x = 0 in the function
f(x) = 2-2x
f(-1) = 2-2(0) = 2-0=2
so
at x = 0, y = 2
FOR x = 1
substitute x = 1 in the function
f(x) = 2-2x
f(-1) = 2-2(1) = 2-2=0
so
at x = 1, y = 0
FOR x = 2
substitute x = 2 in the function
f(x) = 2-2x
f(-1) = 2-2(2) = 2-4=-2
so
at x = 2, y = -2
Thus combining all the output or y values correspond to the given input values, we get the range of the function.
Thus, the range of the function in ascending order is:
Range R = {-2, 0, 2, 4}

how would i show my work
Answer:
3
Step-by-step explanation:
x x6=18
x=3
Answer:
(18=6 times x) you would divide both sides by 6 since inverse operations and to leave the x by itself. 18/6 is 3 so 3=x
describe what is being done in each step while solving the equation -2x + 6 +6x = 6 ( 2x -3 )
-2x + 6 + 6x = 12x - 18
4x + 6 = 12x - 18
6 = 8 × - 18
24 = 8x
3=x
please solve!
-2x + 6 + 6x = 6 (2x - 3) this is the equation
-2x + 6 + 6x = 12x - 18 distributive property has been applied
4x + 6 = 12x - 18 like terms have been added
6 = 8x -18 4x has been subtracted from both sides
24 = 8x -18 has been added to both sides
3 = x 8 has been divided from both sides
I hope this helps! Let me know if I need to explain more or if I got something wrong. Have a nice day!
Solve for the missing side of the triangle.
Round off answer to the nearest thousandths
(3 decimal places)
SOH CAH TOA
x =
239
14
Х
Answer:
x = 5.943
Step-by-step explanation:
Reference angle = 23°
Side opposite to reference angle = x
Adjacent side = 14
Therefore, we would apply TOA to find x.
Thus:
tan (23) = x/14
Multiply both sides by 14
14 × tan(23) = x
5.94264742 = x
x = 5.943 (to 3 decimal places)
Use Structure The area of a rectangular
playground has been extended on one side.
The total area of the playground, in square
meters, can be written as 352 +22x.
Rewrite the expression to give a possible set
of dimensions for the playground,
Answer:
The width and length of the rectangle are [tex]22[/tex] and [tex]16+x[/tex], for [tex]x > -16[/tex], respectively.
Step-by-step explanation:
From Geometry, we remember that area of the rectangle ([tex]A[/tex]) is defined by:
[tex]A = w\cdot l[/tex] (1)
Where:
[tex]w[/tex] - Width.
[tex]l[/tex] - Length.
In addition, we know that area is described by a first-order polynomial:
[tex]A = 352+22\cdot x[/tex] (2)
Meaning that is the product of another first-order polynomial and a constant. That is:
[tex]A = a\cdot (b+c\cdot x)[/tex] (3)
Now we determine the Great Common Divisor of 352 and 22:
[tex]352 = 2\times 2\times 2 \times 2 \times 2 \times 11[/tex]
[tex]22 = 2\times 11[/tex]
The Great Common Divisor is 22.
Then, the area of the rectangle can be expressed by this expression:
[tex]A = 22\cdot (16+x)[/tex] (3b)
According to this, the width and length of the rectangle are [tex]22[/tex] and [tex]16+x[/tex], for [tex]x > -16[/tex], respectively.

A sculptor uses a constant volume of modeling clay to form a cylinder with a large height and a relatively small radius. The clay is molded in such a way that the height of the clay increases as the radius decreases, but it retains its cylindrical shape. At time t=c, the height of the clay is 8 inches, the radius of the clay is 3 inches, and the radius of the clay is decreasing at a rate of 1/2 inch per minute.
Write an expression for the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r.
Answer:
[tex]\frac{dr}{dh} =-\frac{r}{2h}[/tex]
Step-by-step explanation:
The volume of a cylinder is given by the formula:
V = πr²h,
Where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.
We are to express the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r.
That means we express dr / dh in terms of height h and radius r. To do this, we have to first differentiate the volume with respect to the height, i.e. find dV / dh:
V = πr²h
[tex]\frac{dV}{dh}= \frac{d}{dh} (\pi r^2h)\\\\\frac{dV}{dh}= \pi r^2 + 2\pi rh \frac{dr}{dh} \\\\The\ volume\ is\ constant\ hence\ \frac{dV}{dh}=0.\ We\ get\ that:\\\\0= \pi r^2 + 2\pi rh \frac{dr}{dh}\\\\- \pi r^2 =2\pi rh \frac{dr}{dh}\\\\ \frac{dr}{dh}=-\frac{\pi r^2}{2\pi rh}\\\\ \frac{dr}{dh}=-\frac{r}{2h}[/tex]:

Which function has the graph with the greatest y-intercept?
Answer:
The greatest y-intercept c = 6
Step-by-step explanation:
we know that
slope-intercept form y = mx +c
a) Given that f(x) = [tex]6x + \frac{1}{6}[/tex]
[tex]y = 6x + \frac{1}{6}[/tex]
comparing y = mx +c
slope of the line m = 6 and Y - intercept c= 1/6
b) Given that f(x) = [tex]6x -6[/tex]
y = 6x -6
comparing y = mx +c
slope of the line m = 6 and Y - intercept c= -6
c)
Given that f(x) = [tex]\frac{1}{6} x +6[/tex]
y = [tex]\frac{1}{6} x +6[/tex]
comparing y = mx +c
slope of the line m = [tex]\frac{1}{6}[/tex] and Y - intercept c= 6 ( greatest intercept)
d)
Given that 6 k(x) = x
k(x) = [tex]\frac{1}{6} x[/tex]
y = [tex]\frac{1}{6} x[/tex]
comparing y = m x +c
The slope of the line m =[tex]\frac{1}{6}[/tex] and Y-intercept c=0
Final answer:-
The greatest y-intercept c = 6

If Fran were to paint her living room alone, it would take 6 hours. Her sister Denise
could do the job in 8 hours. How long would it take them working together? If needed,
submit your answer as a fraction reduced to lowest terms.
Answer:
It will take Fran and Denise [tex]3\frac{3}{7}[/tex] hours to paint the living room.
Step-by-step explanation:
Given that:
Time taken by Fran to paint living house = 6 hours
Time taken by Denise = 8 hours
Let,
x be the time taken by both of them.
[tex]\frac{1}{Fran's\ share}+\frac{1}{Denise's\ share}=\frac{1}{x}\\\\\frac{1}{6}+\frac{1}{8}=\frac{1}{x}\\\\\frac{4+3}{24}=\frac{1}{x}\\\\\frac{7}{24}=\frac{1}{x}\\\\x = \frac{24}{7}[/tex]
[tex]x = 3\frac{3}{7}[/tex] hours
Hence,
It will take Fran and Denise [tex]3\frac{3}{7}[/tex] hours to paint the living room.
