triangle ABC with verticales at A(-3,-3) B(3, 3) C(0, 3) is dilated to create triangle abc with verticles at a(-9, -9) B(9, 9) C(0,9)
We can conclude that the dilated triangle abc is similar to the original triangle ABC with a dilation factor of 3,
Dilation is a transformation that performs a proportional resize of a figure. It changes the size of the figure while maintaining its shape and orientation. To dilate triangle ABC to create triangle abc, we can multiply the coordinates of each vertex of ABC by a dilation factor of 3.
The coordinates of the vertices of the original triangle ABC are A(-3,-3), B(3,3), and C(0,3). Multiplying each coordinate by 3 gives the coordinates of the vertices of the dilated triangle abc : A(-9,-9), B(9,9), and C(0,9).
We can compare the two triangles to see how the dilation has affected them. The size of triangle abc is three times larger than that of triangle ABC. The shape and orientation of triangle abc are the same as that of triangle ABC. The vertices of the dilated triangle, abc, are located at three times the distance from the origin as the corresponding vertices of triangle ABC. That is why the coordinates of all vertices of triangle abc are three times the coordinates of the corresponding vertices of triangle ABC. since the triangle was resized proportionally and has the same shape and orientation.

Graph circles A and B in the coordinate plane. circle A with center at (0,0) and radius of 6,circle B with center at (-4,-2) and radius of 4.
A circle can be represented as an equation or on a graph
The equations of the circles are \(x^2 + y^2 = 36\) and \((x + 4)^2 + (y + 2)^2 = 16\)
How to graph the circlesThe equation of a circle is represented as:
\((x - a)^2 + (y - b)^2 =r^2\)
Where:
Center = (a,b)
Radius = r
For circle A, we have the equation to be:
\((x - 0)^2 + (y - 0)^2 =6^2\)
\(x^2 + y^2 = 36\)
For circle B, we have the equation to be:
\((x + 4)^2 + (y + 2)^2 =4^2\)
\((x + 4)^2 + (y + 2)^2 = 16\)
Hence, the equations of the circles are \(x^2 + y^2 = 36\) and \((x + 4)^2 + (y + 2)^2 = 16\)

What is the [h*] in a solution if the [oh-] = 5.42 x 10-5 m?
The [h*] in the given solution is 1.84 x 10^-10 M. It is important to note that this value indicates the concentration of hydronium ions (H3O+) in the solution, which is also known as the acidity of the solution.
The [h*] in a solution can be calculated using the formula Kw = [h*][oh-], where Kw is the ion product constant of water, which is equal to 1.0 x 10^-14 at 25°C. By substituting the given value of [oh-] = 5.42 x 10^-5 m into this equation, we can solve for [h*] as follows:
Kw = [h*][oh-]
1.0 x 10^-14 = [h*] x 5.42 x 10^-5
[h*] = 1.0 x 10^-14 / 5.42 x 10^-5
[h*] = 1.84 x 10^-10 M
Therefore, the [h*] in the given solution is 1.84 x 10^-10 M. It is important to note that this value indicates the concentration of hydronium ions (H3O+) in the solution, which is also known as the acidity of the solution. A lower [h*] value indicates a more basic solution, while a higher [h*] value indicates a more acidic solution.

Describe the translation in each function as it relates to the graph of f(x) = x.g(x)=x+7g(x)=x-5g(x) = (x + 2)g(x)=(x-7.5)
EXPLANATION
We are asked to describe the translation of the functions with respect to f(x) =x
To translate the function up and down, you simply add or subtract numbers from the whole function. If you add a positive number (or subtract a negative number), you translate the function up. If you subtract a positive number (or add a negative number), you translate the function down.
In function notation, to shift a function left, add inside the function's argument: f(x + b) shifts f(x) b units to the left. Shifting to the right works the same way, f(x - b) shifts f(x) b units to the right.
To do so, we will have to plot the graph of each function and compare it with f(x) represented by the red lines below
Part A
\(\begin{gathered} when \\ g(x)=x+7 \end{gathered}\)Thus, we will have
\(shifting\text{ to the left by 7 units}\)For part B
when
\(g(x)=x-5\)The translation here is
\(A\text{ shifting to the right by 5 units}\)Part C
For the function
\(g(x)=(x+2)\)The graph is
Thus, we have the translation as A horizontal shift to the left by 2 units
Part D
The given function is
\(g(x)=(x-7.5)\)The transformed graph is
The translation is a shift to the right by 7.5 units

From 1900 to 1960, The life expectancy (in years) increased at a relatively constant rate of 0.401 years. In 1942, the life expectancy was 62.9 years old.
In what year will the life expectancy reach 75 years old?
The life expectancy will reach 75 years old in the year 1970.
We have,
Let's start by defining the variables:
L = life expectancy in years
t = time in years since 1900
We know that from 1900 to 1960, life expectancy increased at a constant rate of 0.401 years per year.
So, we can write the following equation to represent the relationship between L and t:
L = 0.401t + b
where b is the life expectancy in 1900.
To find b, we can use the fact that the life expectancy in 1900 was around 47 years old.
b = 47
So, the equation becomes:
L = 0.401t + 47
We also know that in 1942, the life expectancy was 62.9 years old.
So, we can use this information to find the value of t in 1942:
62.9 = 0.401t + 47
Solving for t, we get:
t = (62.9 - 47) / 0.401 = 39.15
In 1942,
t = 39.15.
To find the year when the life expectancy reaches 75 years old, we can plug in L = 75 into the equation and solve for t:
75 = 0.401t + 47
Solving for t.
t = (75 - 47) / 0.401 = 69.82
So, the life expectancy will reach 75 years old in the year:
1900 + 69.82 = 1969.82
Therefore,
The life expectancy will reach 75 years old in the year 1970.

a helium filled balloon has a volume of 50.0 l at 25 and 1.08 atm what volume will it have at .855 atm and 10.0 c
The volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L, calculated using the ideal gas law equation.
To compute this problem, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
First, we need to convert the initial temperature of 25 °C to Kelvin:
T1 = 25 + 273.15 = 298.15 K
Next, we can rearrange the ideal gas law equation to solve for V2:
V2 = (P1 * V1 * T2) / (P2 * T1)
We have:
P1 = 1.08 atm (initial pressure)
V1 = 50.0 L (initial volume)
P2 = 0.855 atm (final pressure)
T2 = 10.0 °C (final temperature)
Converting the final temperature to Kelvin:
T2 = 10 + 273.15 = 283.15 K
Substituting the values into the equation:
V2 = (1.08 * 50.0 * 283.15) / (0.855 * 298.15)
V2 ≈ 42.81 L
Therefore, the volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L.

In a basketball game, Alison made 6 of 13 free shots.
Madhu made 5 of 9 free shots. Who played better? Explain.
Answer:
Madhu played better.
Step-by-step explanation:
Change both fractions to where they have the same denominator to see which one is bigger. The smallest possible denominator between the two fractions is 117.
To get the 13 in 6/13 to become 117, you had to multiply it by 9. Whatever you do to the denominator, you must do to the numerator.
6 x 9 = 54.
Allison's fraction is now 54/117.
To get the 9 in 5/9 to become 117, you had to multiply the 9 by 13. Whatever you do to the denominator, you must do to the numerator.
5 x 13 = 65
Madhu's fraction is now 65/117
By looking, 65 is larger than 54, so Madhu had a larger number of shots compared to shots not made than Allison.

A plane can fly 640 miles in the same time as it takes a car to go 240 miles. If the car travels 100 mph slower than the plane, find the speed (in mph) of the plane.
Answer:
Let s be the speed of the plane. Then s - 100 is the speed of the car.
640/s = 240/(s - 100)
640(s - 100) = 240s
8(s - 100) = 3s
8s - 800 = 3s
5s = 800, so s = 160 mph
The speed of the plane is 160 mph, and the speed of the car is 60 mph.
