Step-by-step explanation:
which of the formulas would indicate that the graph h(x) was stretched in the horizontal direction by a factor of 3?
The correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]
To address the question about the horizontal stretching of the graph of a function [tex]\( f(x) \)[/tex] by a factor of 3, we need to understand how transformations affect the graph of a function. Here are the steps to determine the correct transformation:
1. Identify the Base Function: Recognize that the graph in question is of some function [tex]\( f(x) \)[/tex]. We don't need to know the form of \( f(x) \) to understand how it will be transformed.
2. Understand Horizontal Stretching: A horizontal stretch by a factor of [tex]\( a \)[/tex] is achieved by replacing every [tex]\( x \)[/tex] in the function with [tex]\( \frac{x}{a} \)[/tex]. In this case, [tex]\( a = 3 \).[/tex]
3. Apply the Stretch to the Function: Replace [tex]\( x \)[/tex] with [tex]\( \frac{x}{3} \)[/tex]in the function [tex]\( f(x) \).[/tex]
4. **Write Down the Transformed Function**: The new function after the horizontal stretch will be [tex]\( f\left(\frac{x}{3}\right) \).[/tex]
5. **Choose the Correct Answer**: Look for the choice that represents the transformation [tex]\( f\left(\frac{x}{3}\right) \).[/tex]
The correct transformation that indicates a horizontal stretch by a factor of 3 is:
[tex]\[ f\left(\frac{x}{3}\right) \][/tex]
This means that for any given value of [tex]\( x \)[/tex] in the original function, its corresponding point on the graph will now be three times further away from the y-axis, thus stretching the graph horizontally. If the original function had a point at [tex]\( (x, y) \)[/tex], the new function after the stretch will have a corresponding point at [tex]\( (3x, y) \)[/tex], which means the x-values have been stretched out.
Now, from the options given in the image:
1. [tex]\( h(3x) \)[/tex] represents a horizontal compression by a factor of 3, not a stretch.
2. [tex]\( h\left(\frac{x}{3}\right) \)[/tex] is the correct representation of a horizontal stretch by a factor of 3.
3. [tex]\( h(x) + 3 \)[/tex] represents a vertical shift upwards by 3 units.
4. [tex]\( 3h(x) \)[/tex] represents a vertical stretch by a factor of 3.
Therefore, the correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]
What is the area of the following circle R=1
The area of the circle with [tex]\(r = 1\)[/tex] is [tex]\(\pi\)[/tex].
The area ([tex]\(A\)[/tex]) of a circle is given by the formula:
[tex]\[A = \pi r^2\][/tex]
Where [tex]\(r\)[/tex] is the radius of the circle.
Given that [tex]\(r = 1\)[/tex], we can substitute this value into the formula:
[tex]\[A = \pi \times (1)^2\][/tex]
[tex]\[A = \pi \times 1\][/tex]
[tex]\[A = \pi\][/tex]
Therefore, the area of the circle with [tex]\(r = 1\)[/tex] is [tex]\(\pi\)[/tex].
Which graph best represents the solution to the system of equations shown below?
y = -4x + 19
y = 2x + 1
First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.
Rearrange equations
[tex]4x + y = 19[/tex]
[tex] - 2x + y = 1[/tex]
To cancel y, we must do equation 1 minus equation 2. Similarly:
[tex]4x - - 2x = 4x + 2x = 6x[/tex]
[tex]19 - 1 = 18[/tex]
[tex]6x = 18[/tex]
[tex]x = 18 \div 6 = 3[/tex]
So the x coordinate is 3.
The y coordinate can be found with substitution of x into one of the equations:
[tex]y = 2x + 1 = 2(3) + 1 = 7[/tex]
So where the two lines intersect is at the point (3, 7), which is the solution to the equations.
Answer:
The correct option is 2.
Step-by-step explanation:
The given system of equations is
[tex]y=-4x+19[/tex] ..... (1)
[tex]y=2x+1[/tex] ..... (2)
The slope intercept form of a line is
[tex]y=mx+b[/tex] .... (3)
where, m is slope and b is y-intercept.
From (1) and (3), we get
[tex]m=-4,b=19[/tex]
The slope of first line is -4 and the y-intercept is 19. It means it is a decreasing line and intersect the y-axis at (0,19).
From (2) and (3), we get
[tex]m=2,b=1[/tex]
The slope of first line is 2 and the y-intercept is 1. It means it is an increasing line and intersect the y-axis at (0,1).
Put y=0, to find the x-intercepts.
[tex]0=-4x+19\Rightarrow x=\frac{19}{4}=4.75[/tex]
[tex]0=2x+1\Rightarrow x=\frac{-1}{2}=-0.5[/tex]
Therefore the x-intercept of first line is 4.75 and the x-intercept of the second line is -0.5.
Only the second graph satisfy all the above condition.
One solving the given equation we get
[tex]-4x+19=2x+1[/tex]
[tex]19-1=2x+4x[/tex]
[tex]18=6x[/tex]
Divide both sides by 6.
[tex]3=x[/tex]
Put this value in equation (1).
[tex]y=-4(3)+19=-12+19=7[/tex]
Therefore the solution of the given system of equation is (3,7).
Hence the correct option is 2.

The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.
So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.
Answer:
E. 46
Step-by-step explanation:
The perimeter of a square or rectangle can be found by using the following formula:
(length + legnth) + (width + width) = perimeter
Our length here is 15 and the width is 8, so substitute the values into the equation.
(15 + 15) + (8 + 8) = perimeter
Now solve
(15 + 15) + (8 + 8)
(30) + (8 + 8)
(30) + (16)
=46
Therefore, the perimeter (and answer) is E. 46

In the diagram below what is the relationship between the number of rectangles in the perimeter of the figure they form?
Answer:
the correct answer is the third one. (1, 16), (2, 20), (3, 24)
Step-by-step explanation:
A perimeter is a path that surrounds a two-dimensional shape.
In the first case, 1 rectangle, the perimeter is the sum of all the sides:
Perimeter = 6 + 2 + 6 + 2 = 16
In the second case, 2 rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 6 + 2 + 2 = 20
In the third case, three rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 2 + 6 + 2 + 2 + 2 = 24
In none of the cases, you take into consideration the interal sides. Just the external sides, so the correct answer is the third one.
In triangle XYZ, angle Z is a right angle. If sinX=3/4, find tanY.
ANSWER
[tex]\tan(x) = \frac{3\sqrt{7}}{7} [/tex]
EXPLANATION
[tex] \sin(x) = \frac{Opposite}{hypotenuse} [/tex]
[tex]\sin(x) = \frac{3}{4} [/tex]
This means the opposite side is 3 units and the hypotenuse is 4 units.
We use Pythagoras Theorem to find
[tex] { |ZX| }^{2} + {3}^{2} = {4}^{2} [/tex]
[tex]{ |ZX| }^{2} +9=16[/tex]
[tex]{ |ZX| }^{2} =16 - 9[/tex]
[tex]{ |ZX| }^{2} = 7[/tex]
[tex]{ |ZX| } = \sqrt{7} [/tex]
[tex] \tan(x) = \frac{opposite}{adjacent} [/tex]
[tex] \tan(x) = \frac{3}{ \sqrt{7} } [/tex]
[tex] \tan(x) = \frac{3}{ \sqrt{7} } \times \frac{\sqrt{7}}{\sqrt{7}} [/tex]
[tex]\tan(x) = \frac{3\sqrt{7}}{7} [/tex]
Final answer:
Given sin(X) = 3/4 in a right-angled triangle XYZ, by using trigonometric identities and the Pythagorean theorem, we find that tan(Y) is 1/3.
Explanation:
In triangle XYZ with angle Z being a right angle (90 degrees or π/2 radians), if we are given that sin(X) = 3/4, we can use trigonometric identities to find tan(Y). Since sin(X) is the ratio of the opposite side to the hypotenuse in a right-angled triangle, we have a side opposite angle X which is 3 units long and a hypotenuse that is 4 units long. From this, we can deduce that the side adjacent to angle X, which is also the side opposite to angle Y, is 1 unit long (using the Pythagorean theorem, as the square of the hypotenuse is equal to the sum of the squares of the other two sides: 3² + 1² = 4²).
Now, to find tan(Y), which is the ratio of the side opposite to Y to the side adjacent to Y, we just take the length of the side opposite to X (which is the same as the side adjacent to Y) and the length of the hypotenuse. Therefore, tan(Y) = opposite side / adjacent side, which in this case is 1/3.

Given the box plot, will the mean or the median provide a better description of the center?
box plot with min at 10.5, Q1 at 11.5, median at 12.5, Q3 at 13.5, max at 15
The mean, because the data distribution is symmetrical
The mean, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the right
Answer:
The median, because the data distribution is skewed to the right
Step-by-step explanation:
Min= 10.5
Q1 = 11.5
Median = 12.5
Q3= 13.5
Maximum = 15
The data is skewed towards the right because more values towards the right side as compared to the left side.
For data to be symmetrical, it has same shape on both sides of the median, which in our case is not possible.
So, for skewed data we always prefer median because it is less affected by the outliers and if mean is chosen, the value of mean is biased towards the side that has larger values while median does not get affected by it. So, we choose median.
our correct option will be:
The median, because the data distribution is skewed to the right

Piping Hot Pizza's busiest days fall on the weekends. It offers its employees time-and-a-half pay on Saturdays and double-time pay on Sundays. Lisa Edwards normally earns $10.50 an hour. If, in addition to her regular 25 hours, she works 4 hours on Saturday and 6 hours Sunday, what is her total pay for the week?
Show work!
Answer:
$451.5
Step-by-step explanation:
For saturdays, Edward will earn 1.5 times the normal (10.50). So saturday hourly pay is 1.5 * 10.5 = $15.75
For sundays, Edward will earn twice the normal (10.50). So sunday hourly pay is 2 * 10.5 = $21
Edward's hours:
Regular 25 hours: 25 * 10.5 = $262.5
Saturday 4 hours: 4 * 15.75 = $63
Sunday 6 hours: 6 * 21 = $126
Total Pay = 262.5 + 63 + 126 = $451.5
Final answer:
Lisa Edwards' total pay for the week is $451.50, which is the sum of her regular pay for 25 hours, time-and-a-half pay for 4 hours on Saturday, and double-time pay for 6 hours on Sunday.
Explanation:
Lisa Edwards' total pay for the week can be calculated by considering her regular hourly wage, her time-and-a-half pay for Saturday, and her double-time pay for Sunday. Her regular hourly rate is $10.50 per hour. For her regular 25 hours of work, she would earn $10.50 x 25 = $262.50.
On Saturday, Lisa earns time-and-a-half. This means she gets $10.50 x 1.5 = $15.75 per hour for 4 hours, which totals to $15.75 x 4 = $63.00.
On Sunday, Lisa earns double-time pay, which amounts to $10.50 x 2 = $21.00 per hour. For 6 hours of work on Sunday, she will earn $21.00 x 6 = $126.00.
To find out Lisa's total weekly pay, add her earnings from all the days: $262.50 (regular hours) + $63.00 (Saturday) + $126.00 (Sunday) = $451.50.

Which statements can be used to describe the original functions f(x) and g(x)? Select three options. (See picture attached) PLEASE ANSWER QUICKLY I AM TIMED!!!!
Options 1, 2, and 3 are valid based on the given information and calculations.
1. When added, the sum of the y-intercepts must be 8:
- If the y-intercepts are denoted as b₁ and b₂ for f(x) and g(x) respectively, then . [tex]b_1 \times b_2 = 8[/tex].
2. When multiplied, the product of the y-intercepts must be 8:
- This translates to [tex]b_1 \times b_2 = 8[/tex].
3. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change:
- This implies that the slopes of the lines have opposite signs.
Checking the given U-turn points (-2, 8) and (8, 2). The slope (rate of change) between these points can be calculated as:
[tex]\[ m = \frac{change\:in\:y}{change\:in\:x} \][/tex]
[tex]\[ m = \frac{2 - 8}{8 - (-2)} = \frac{-6}{10} = -\frac{3}{5} \][/tex]
4. f(x) could have a rate of change equal to 3 and g(x) could have a rate of change of -3:
- This statement is inconsistent with the calculated slope.
5. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of -1:
- This statement is also inconsistent with the calculated slope.
Therefore, options 1, 2, and 3 are valid based on the given information and calculations.
Answer:
1 When multiplied the product of the y intercepts must be 8
2 Either f(x) or g (x) has a positive rate of change and the other has a negative rate of change
3 f (x) could have a rate of change equal to 2 and g (x) could have a rate change of -1

On average, seawater contains approximately 1.2 ounces of salt per liter.how many gallons of seawater to the nearest tenth of a gallon would contain 2.5 pounds of salt?
To find how many gallons of seawater contain 2.5 pounds of salt, convert the salt to ounces (40 ounces) and divide by the salinity concentration (1.2 ounces per liter) to get 33.33 liters. Then convert liters to gallons, resulting in approximately 8.8 gallons of seawater.
To solve this problem, we need to convert all units to be compatible and calculate the amount of seawater needed to obtain 2.5 pounds of salt based on the salinity given.
First, we convert 2.5 pounds of salt to ounces because the salinity is given as 1.2 ounces per liter. Since 1 pound is equal to 16 ounces, we have 2.5 pounds * 16 ounces/pound = 40 ounces of salt.
Next, we divide the total ounces of salt by the salinity concentration to find out how many liters of seawater we need:
40 ounces of salt / 1.2 ounces of salt per liter = 33.33 liters of seawater.
Then, we convert liters of seawater to gallons. There are approximately 3.785 liters in a gallon, so:
33.33 liters / 3.785 liters per gallon = 8.8 gallons
Therefore, to the nearest tenth of a gallon, it would take 8.8 gallons of seawater to contain 2.5 pounds of salt.
Three cars are driving on a racetrack. The mean speed of the three cars is 100 miles per hour. Car X drives 109 miles per hour and Car Y drives 111 miles per hour. Use the mean to estimate the speed of Car Z. Then find the actual speed of Car Z.
Estimate the speed of Car Z. Choose the correct answer below.
A.
The speed of Car Z is about 100 miles per hour.
B.
The speed of Car Z is less than 100 miles per hour.
C.
The speed of Car Z is greater than 100 miles per hour.
D.
It is impossible to estimate the speed of Car Z.
Answer:
B
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 109, 111, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(109+111+Z)/3
300=220+Z
80=Z
The speed of Car Z is less than 100.
The correct answer is B. The speed of Car Z is less than 100 miles per hour.
To estimate the speed of Car Z, we can use the given mean speed of the three cars. The mean speed is given as 100 miles per hour. Since Car X is driving at 109 miles per hour and Car Y is driving at 111 miles per hour, both of these speeds are above the mean. To maintain an average of 100 miles per hour, Car Z must be driving at a speed less than 100 miles per hour to balance the speeds of Car X and Car Y, which are pulling the average up.
To find the actual speed of Car Z, we can use the formula for the mean speed of the three cars:
[tex]\[ \text{Mean speed} = \frac{\text{Speed of Car X} + \text{Speed of Car Y} + \text{Speed of Car Z}}{3} \][/tex]
Given that the mean speed is 100 miles per hour, we can plug in the known values and solve for the speed of Car Z:
[tex]\[ 100 = \frac{109 + 111 + \text{Speed of Car Z}}{3} \][/tex]
Multiplying both sides by 3 to clear the denominator:
[tex]\[ 300 = 109 + 111 + \text{Speed of Car Z} \][/tex]
Adding the speeds of Car X and Car Y:
[tex]\[ 300 = 220 + \text{Speed of Car Z} \][/tex]
Subtracting 220 from both sides to isolate the speed of Car Z:
[tex]\[ \text{Speed of Car Z} = 300 - 220 \] \[ \text{Speed of Car Z} = 80 \text{ miles per hour} \][/tex]
Thus, the actual speed of Car Z is 80 miles per hour, which confirms our initial estimation that it is less than 100 miles per hour.
Heather received $100 for her 13th birthday if she saves it in a bank with 3% interest compounded quarterly how much money will she have in the bank by her 16th birthday
Answer:
109.38
Step-by-step explanation:
Recall the formula for compound interest is as follows:
A = P·(1 + r/n)nt , where
P = principal amount (initial amount deposited)
r = annual rate of interest (in decimal form)
t = # of years amount is deposited for
n = # of times interest is compounded per year
A = amount accumulated after t years, including interest
The problem asks how much money Heather will have in the bank by her 16th birthday when she deposited $100 on her 13th birthday in a bank with 3% interest compounded quarterly. From this, we have the following information:
P = $100
r = 0.03 ==> 3%/100% = 0.03
t = 3 years ==> 16 - 13 = 3
n = 4 ==> since there are 12 months per year and 12/4 = 3 months,
then interest is compounded every 3 months which is a total of 4 times per year
Therefore,
A = P(1 + r/n)nt
= 100(1 + 0.03/4)4·3
= 100(1 + 0.0075)12
= 100(1.0075)12
= 109.38069
≈ 109.38
Thus, Heather will have $109.38 in the bank by her 16th birthda
