I put the equation into a GeoGebra graphing calculator, and y=sin(x-2) matches the graph.
The function represents the given graph is y = sin(x - 2).
What is the translating a graph?"Translating a graph means that moving it along the x or y axis by certain units."
Translating a function y = f(x):1) For a function of the type y = f(x) + k
If k > 0, the graph of y = f(x) will translate up(along positive Y-axis) by k units.
If k < 0, the graph of y = f(x) will translate down(along negative Y-axis) by k units.
2) For a function of the type y = f(x + m)
If m > 0, the graph of y = f(x) will translate left(along negative X-axis) by m units.
If m < 0, the graph of y = f(x) will translate right(along positive X-axis) by m units.
From given example,
The function represents the given graph is y = sin(x - 2).
This means, the function y = sin(x) is translated right by angle 2 (degrees / radians) as shown in the following figure.

Answers
Answer:
there will be 19 $100 bills
and 11 $10 bills
Step-by-step explanation:
[tex]100*19=1900\\10*11=110\\1900+110=2010[/tex]
Answer:
11
Step-by-step explanation:
Let x be how many $10 bills there are.
Let y be how many $100 bills there are
x + y = 30
x = 30 - y
10x + 100y = 2010
10(30 - y) + 100y = 2010
300 - 10y + 100y = 2010
-10y + 100y = 2010 - 300
90y = 1710
y = 1710 / 90
y = 19
x = 30 - 19
x = 11
Solve this equation.
3.5(2.25 + x) = 14
Answers
Answer:
1.75
Step-by-step explanation:
Use the distributive property first.
(3.5 x 2.25) (3.5 x X) = 14
7.875 + 3.5x = 14 Now subtract 7.875 from both sides
3.5x = 6.125 Now divide 3.5 by both sides
x = 1.75
The equation 3.5(2.25 + x) = 14 is solved by first distributing 3.5 through the parentheses, then isolating x on one side, yielding a result of x = 1.75.
Explanation:In this mathematical equation, the first step is to distribute 3.5 to (2.25 + x). The result is 7.875 + 3.5x = 14. We then subtract 7.875 from both sides to isolate the term with x which gives 3.5x = 6.125. Finally, to solve for x, we divide both sides by 3.5. This gives us x = 1.75.

Q3. Express 984. 6080 correct to
a. 2 decimal places _______________
b. 4 significant figures _____________
c. 3 decimal places ________________
d. the nearest hundredth___________ help
Answers
Answer:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Step-by-step explanation:
Answers to the approximation questions above are supplied below.
First, you needs to know approximation processes:
Step 1: Keep the required number of digits in question.
Step 2: Before rounding off the remaining digits, look at the next digit to the required number of accuracy, if it is 5 or more, increase the last digit of the number you're keeping by 1, otherwise leave it as it is and round down to zero all the unwanted digits.
Similarly, there is need know the meaning of each degree of accuracy.
1. Decimal places: These are the number of digits occurring after the decimal point. E.g. a set of figures in 1 decimal place has only one digit after decimal point, i.e. 65.4. In the case of the question above,
a) 984.6080 = 984.61 to 2 decimal places
c) 984.6080 = 984.608 to 3 decimal places
2. Significant figures: Basically, these are nonzero digits in a set of figures. However, when zero is in the middle of nonzero digits, i.e, 3045, such zero is a significant figure. In the question above,
b) 984.6080 = 984.6 to 4 significant figures
3. Hundredth: Under place value system, hundredth of a set of figures is located at two digits after the decimal point. In other words, hundredth is same as two decimal places so the same approach is required for the two. Thus;
d) 984.6080 = 984.61 to the nearest hundredth
You can see that the result for both 2 decimal places and nearest hundredth are the same, that is, 984.6080 = 984.61 to 2 decimal places and to the nearest hundredth respectively.
Therefore, the answers are summarized thus:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Answer:
984.6080
a. 2 decimal places
984.61
b. 4 significant figures
984.6
c. 3 decimal places
984.608
d. the nearest hundredth

What does the guinea pig weigh measured in kilograms?
Answers
The weight of the guinea pig measured in kilograms is A = 1.130 kg
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the measurement of unit be represented as A
Now , the weight of the guinea pig = 1,130 grams
where from the unit conversion
1000 grams = 1 kg
So , weight of the guinea pig measured in kilograms A = 1,130 grams / 1000
On simplifying , we get
The weight of the guinea pig measured in kilograms A = 1.130 kilograms
Therefore , the value of A is 1.13 kg
Hence , the measurement is A = 1.13 kg

The guinea pig weight measured in kilograms is 1.13kgs.
To convert the weight of a guinea pig from grams to kilograms, you need to understand the relationship between these units:
In the metric system, 1 kilogram (kg) is equal to 1,000 grams (g).
Start with the weight of the guinea pig: 1,130 grams.
Use the conversion factor: 1,000 grams = 1 kilogram.
Divide the weight in grams by the conversion factor to find the weight in kilograms.
1,130 grams ÷ 1,000 = 1.13 kilograms.

Answers
Answer: The distance of frog from the base of the stump is 5.16 feet ( approx)
Step-by-step explanation:
Given, A frog sitting on a stump 3 feet high hops off and lands on the ground.
During its leap, its height h in feet is given by [tex]h= -0.5d^2 + 2d + 3[/tex], where [tex]d[/tex] is the distance from the base of the stump.
When the stump landed on the ground, h= 0 .
So put h=0 in the given equation , we get
[tex]0=-0.5d^2 + 2d + 3\\\\\Rightarrow\ 0.5d^2-2d-3=0[/tex]
Multiply both sides by 2 , we get
[tex]d^2-4d-6=0\\\\\Rightarrow\ d=\dfrac{-(-4)\pm\sqrt{4^2-4(1)(-6)}}{2(1)}\\\\=\dfrac{4\pm\sqrt{16+24}}{2}\\\\=\dfrac{4\pm\sqrt{40}}{2}\\\\=\dfrac{4\pm2\sqrt{10}}{2}=2\pm\sqrt{10}[/tex]
[tex]i.e.\ d=2-\sqrt{10}\ \ or\ \ d=2+\sqrt{10}\\\\\ i.e. d=2-3.1622\ \ or\ \ d=2+3.1622\\\\ i.e. d= -1.1622\ \ or\ \ d=5.1622\approx5.16[/tex]
Since , distance cannot be negative.
Hence, the distance of frog from the base of the stump is 5.16 feet ( approx).

P is located at (-2, 8)Q is located at ( 6, 8) R( is located at (6, 2) S is located at (-5, 0)To find a distance between two points or the length of the segment, we use the following formula:
[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
Because the two points P and Q are located at the same libe y = 8
=> the lenght of PQ = [tex]\sqrt{(6- (-2))^{2} } = \sqrt{8^{2} } = 8\\[/tex]
Because the two points R and Q are located at the same libe x = 6

There are 3 less than twice as many cats than dogs in the local animal shelter. If there are 210 cats and
dogs combined, how many dogs are in the animal shelter?
Answers
There are 71 dogs in the local animal shelter.
To determine the number of dogs and cats in the shelter, let's denote the number of dogs by D and the number of cats by C. According to the problem statement, there are twice as many cats as dogs, minus three. Mathematically, this is represented as C = 2D - 3. We also know that the combined total of cats and dogs is 210, which can be expressed as C + D = 210. To find the number of dogs, we can solve these two equations simultaneously.
From the first equation, we solve for C in terms of D: C = 2D - 3.
Substitute C into the second equation: (2D - 3) + D = 210.
Combine like terms: 3D - 3 = 210.
Add 3 to both sides of the equation: 3D = 213.
Divide both sides by 3 to solve for D: D = 71.
Therefore, there are 71 dogs in the local animal shelter.

Subtracting smaller 3-digit numbers from 920 results in 3-digit answers, subtracting larger 3-digit numbers gives 2-digit answers, and subtracting even larger 3-digit numbers results in 1-digit answers. Examples include: 920 - 120 = 800, 920 - 825 = 95, and 920 - 915 = 5.
Explanation:This question involves simple subtraction operations. Here are three subtraction equations that meet the conditions:
For a 3-digit result: 920 - 120 = 800. Here, subtracting a 3-digit number (120) from our original number (920) results in a 3-digit number (800). For a 2-digit result: 920 - 825 = 95. In this case, subtracting a bigger 3-digit number (825) leaves us with a 2-digit number (95). For a 1-digit result: 920 - 915 = 5. Subtraction of an even larger 3-digit number (915) results in a 1-digit number (5).

Explanation:To find three subtraction equations that show the difference when subtracting a 3-digit number from 920, we need to consider all possible scenarios for the difference.
The smallest possible difference would be a 1-digit number.
To get a 1-digit number, 2-digit number, or a 3-digit number as the result while subtracting a 3-digit number from 920, here are three equations:
• The smallest possible difference would be a 1-digit number. 920 - 911 = 9
• The next possible difference would be a 2-digit number. 920 - 815 = 105
• The largest possible difference would be a 3-digit number. 920 - 100 = 820
In each equation, we started with 920 and subtracted a 3-digit number. Given that the numbers we subtract are less than 920, it becomes possible to get a 1-digit, 2-digit, or 3-digit result.

Anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, and the probability that it is canvas is 0.7. The probability that it is pink and canvas is 0.5. What is the probability that it is pink or canvas. A) 0.3 B) 0.5 C) 0.9 D) 1.4
Answers
The probability that the backpack is pink or canvas is option (c) 0.9.
The probability that the backpack is pink or canvas can be calculated using the formula for the probability of the union of two events:
P(A or B) = P(A) + P(B) - P(A and B).
According to the question,
A represents: the event that the backpack is pink
B represents: the event that the backpack is the canvas
Substituting the given probabilities, we get:
P(pink or canvas) = 0.7 + 0.7 - 0.5 = 0.9.
So, the probability that the backpack is pink or canvas is option (c) 0.9.

A cylinder with height 10 inches and radius 4 inches is filled with water. The water is poured into a bowl
(hemisphere) with radius 5 inches. Sketch a cylinder and a hemisphere with dimensions labeled. If all the water
will fit, tell how much empty space remains in the bowl. If all the water will not fit, tell how much water is left in
the cylinder. (leave your answer in terms of pi)
Answers
Answer:
Volume of water left in the cylinder=[tex]76\frac{2}{3}\pi \:in^3[/tex]
Step-by-step explanation:
Height of the Cylinder=10 inches
Radius of the cylinder=4 Inches
Volume of the Cylinder
[tex]=\pi r^2h\\=4^2*10\pi\\=160\pi\:in^3[/tex]
Radius of the Hemisphere=5 Inches
[tex]\text{Volume of a Hemisphere}=\frac{2}{3}\pi r^3\\ =\frac{2}{3}\pi *5^3\\=\frac{250\pi}{3} in^3[/tex]
Since the Volume of the cylinder is greater than the Volume of the bowl, all the water will not fit.
[tex]\text{Therefore: volume of water left} =160\pi-\frac{250\pi}{3}\\=76\frac{2}{3}\pi \:in^3[/tex]
Help worth 10 points!!
Answers
Answer:
the answer is B
Step-by-step explanation:
the line is a negative slope so therefore the answer must be negative, use the simple rise over run method to find the slope like normal! :)
We can find 2 points on the graph to solve for the slope; (-2, 0) and (2, -3)
Slope formula: y2-y1/x2-x1
= -3-0/2-(-2)
= -3/4
Therefore, the answer is B.
