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}

A diagram of a coin is shown.
What is the approximate circumference of the coin? Use 3.14 as an estimate for Pi.
A-21 mm
B-3mm
C-66mm
D-84mm
Answer:
C. 66 mm (using 3.14, it would be 65.94 mm)
Step-by-step explanation:
From what I know, the radius of this coin is 10.5 mm.
The formula for the circumference of a circle is 2πr or πd.
In this case we're using 3.14 for π.
(2 * 10.5) * 3.14
21 * 3.14
21 * 3.14 is the same as 62.8 + 3.14
62.8 + 3.14
65.94 mm
This is close to 66 mm, which was C, so that is the answer.
Two values, x and y, are the same distance from zero on the number line. the value of x is negative and the value of y is positive. what is x + y
Answer:
x + y = 0
Step-by-step explanation:
x and y are both the same distance from 0 on the number line. That means they are additive inverses (or opposites). Knowing this law, additive inverses always equal 0.

How many different ways are there for the runners to finish? Show your work for full credit.
Answer:
There are 3,628,800 different ways for the runners to finish.
Step-by-step explanation:
Arrangments of x elements:
The number of possible arrangments of x elements is given by the following formula:
[tex]A_{x} = x![/tex]
In this question:
10 different runners, which means that the number of different ways that there are for the runners to finish is an arrangment of 10 elements. So
[tex]A_{10} = 10! = 3628800[/tex]
There are 3,628,800 different ways for the runners to finish.

in the year 2010, the luxury bike industry had two bike manufactures splendor and passion with the market shares of 30% and 70%,respect. in 2011 the overall market for the product increased by 20% and a new player yahma also entered and cpatures the 10% of the market share.
Answer: 50%
Step-by-step explanation:
In 2010, there were only 2 bike manufacturers and they had market shares of 30% and 70%.
A new manufacturer joins the market and captures 10% of the market share and Splendor increases to 40% of market share.
Market shares:
Yamaha = 10%
Splendor = 40%
Passion = 100% - 10% - 40%
= 50%

A golf tournament has five rounds. The players are given scores for each round based on how many strokes they are above or below 72. Ricky has recorded his score for each of the 5 rounds.
Strokes - how many times a player swings the club or hit the ball
Round ------------------------------------------------1 2 3 4 5
Number of Strokes Above or Below 72 -5 +6 -2 +4 +5
Write an expression to represent Ricky's total number of strokes for the five rounds.
What was his average number of strokes per round? Show your work.
Answer:
(A) ∫₁⁵[Xₙ + k] where n ranges from 1 to 5
(B) 73.6
Step-by-step explanation:
The question is clear enough. Kudos!
So there are many players but we're focusing on Ricky.
Ricky has already recorded his score for each of the 5 rounds in the tournament.
The number of strokes in Ricky's record are to be added to or subtracted from a given number 72
ROUND 1: [72 - 5] strokes = 67
ROUND 2: [72 + 6] strokes = 78
ROUND 3: [72 - 2] strokes = 70
ROUND 4: [72 + 4] strokes = 76
ROUND 5: [72 + 5] strokes = 77
(A) Write an expression to represent Ricky's total number of strokes for the five rounds.
Do not panic at this first exercise. You are to write an expression which when evaluated, will give the total number of strokes for all five rounds!
You are already given an abstract number '72' to work with in this question.
It is a fixed quantity which influences the value of strokes for each round.
We will represent this by an algebra, if we have to create the above required expression.
The expression will then be:
∫₁⁵[Xₙ + k] where n ranges from 1 to 5
You already know that the sigma sign '∫' represents summation and that's summation from the subscript '1' to the superscript '5'.
X₁ would be -5, X₂ would be +6, X₃ would be -2, X₄ would be +4, X₅ would be +5
K is the constant 72
(B) What was Ricky's average number of strokes per round?
Out of the 5 rounds, the average number of strokes per round would be
[67 + 78 + 70 + 76 +77] ÷ 5
= 368/5 = 73.6
Ralph Chase plans to sell a piece of property for $160000. He wants the money to be paid off in two ways −a short-term note at 9% interest and a long-term note at 7% interest. Find the amount of each note if the total annual interest paid is $12900.
The amount of the 9% note is $___ and the amount of the 7% note is $___?
Answer:
9%=15,000
7%=12,000
thats what i think.
Answer:
The amount of 12% note is $90,000
The amount of 9% note is $80,000
Step-by-step explanation:
Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"
Selling price = $170,000
Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)
Given total annual interest = $18,000
Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)
18,000 = 0.12x + 0.09*(170000 - x)
18,000 = 0.12x + 15,300 - 0.09x
18,000 = 0.03x + 15,300
0.03x = 18,000 - 15,300
0.03x = 2,700
x = 2,700/0.03
x = 90,000
So, the amount of 12% note is $90,000
So long term paid money = $170,000 - $90,000 = $80,000
So, the amount of 9% note is $80,000

The radius of a right circular cone is increasing at a rate of 2 inches per second and its height is decreasing at a rate of 4 inches per second. At what rate is the volume of the cone changing when the radius is 10 inches and the height is 20 inches
Answer:
The volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]
Step-by-step explanation:
Let r be the radius of cone and h be the height of cone
[tex]\frac{dr}{dt}=2 in/s[/tex]
[tex]\frac{dh}{dt}=-4 in/s[/tex]
We have to find the rate at which the volume of cone changing when r=10 in and h=20 in
Volume of cone
[tex]V=\frac{1}{3}\pi r^2 h[/tex]
Differentiate w.r.t t
[tex]\frac{dV}{dt}=\frac{1}{3}\pi (2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]
Substitute the values
[tex]\frac{dV}{dt}=\frac{1}{3}\pi(2\times 10\times 20\times 2+(10)^2\times (-4))[/tex]
[tex]\frac{dV}{dt}=\frac{1}{3}\pi(400)=\frac{400}{3}\pi in^3/s[/tex]
Hence, the volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]
