What is the image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin?
The image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin is (4, -4).
What is dilation at origin?
On the coordinate plane, figures can be magnified. The centre of dilation is frequently the origin. The coordinates of the points in the preimage can be multiplied by the scale factor to get the points in the image if you are distorting a figure that is centered at the origin.
We have to find the image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin.
To find the image after dilation multiply both coordinates (12, -12) by 1/3 which is the same as dividing by 3.
⇒ (12, -12)*1/3 = (4, -4)
Hence, the image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin is (4, -4).

The school's track is 1/4 mile long. If Janice can compete each lap in 1/10 of on hour, what is Janice's running speed? Include units of measure.
Answer: To find Janice's running speed, we need to determine how many miles she runs per hour.
We know that the track is 1/4 mile long and Janice can complete each lap in 1/10 of an hour. To find the total number of miles Janice runs in an hour, we can multiply the length of the track by the number of laps she completes in an hour.
Length of the track * number of laps = total miles
1/4 mile * (1/10 hour)^-1 = total miles
On the second equation, we are using the inverse of the time, to get the number of laps completed in an hour
The speed is distance over time, so we need to express the distance in miles and the time in hours.
So Janice's running speed is 4 miles/hour.

find the y-intercept, the equation of the axisof symmetry, and the x-coordinate of vertex for the graph of f(x)= x^2-3x+5. use this information to graph the function.
The y-intercept of the graph of f(x) = x^2 - 3x + 5 is (0, 5).
The equation of the axis of symmetry is x = (3/2).
The x-coordinate of the vertex is (3/2), and the y-coordinate of the vertex is (5 - (9/4)) = (-1/4).
So the vertex of the graph of f(x) = x^2 - 3x + 5 is (-1/4, (3/2)).
To graph the function, you can start by plotting the vertex, then use the axis of symmetry to reflect the parabola across the line x = (3/2). The y-intercept is the highest point of the parabola if it opens upwards, and the lowest if opens downwards. This can be used to confirm the direction of the parabola.
A quadratic function's U-shaped curve is seen on a parabola graph. A right circular cone and a plane surface intersect to generate one of the conic sections known as a parabola in mathematics. It has a U-shaped symmetry in the plane. The conventional form of a parabola is a graph whose equation takes the form f(x) = ax2+bx+c.

What is a constant of proportionality?The ratio between two quantities that are directly proportional is the constant of proportionality.
When two quantities grow and shrink at the same rate, they are directly proportional.
When y and x are two values that are directly proportional to one another, the proportionality constant k is defined as k=y/x.

Determine the partial fraction expansion for the rational function below: s/(s – 7)(s^2 - 49) S/(s - 7) (s2 - 49) Determine the partial fraction expansion for the rational function below. -25-56/ (5+3) (s^2+ 16) - 2s - 56 / (s +3)(s^2 + 16)
The partial fraction expansion for the rational function
S/ (s - 7) (s^2 - 49) = -25-56/ (5+3) (s^2+ 16) - 2s - 56 / (s +3) (s^2 + 16)
can be found by decomposing it into the sum of simpler fractions.
One way to do this is to use the method of long division and then match the coefficients of the resulting polynomials. The process is as follows:
Divide S by (s - 7) to get a quotient of S1 and a remainder of R1.
Divide R1 by (s^2 - 49) to get a quotient of S2 and a remainder of R2.
Write the expansion as S1 + S2 + R2/(s - 7)(s^2 - 49)
Alternatively, we can use the method of partial fraction decomposition by inspection.
To do this, you will write the rational function as the sum of simpler fractions with the same denominator.
S/ (s - 7) (s^2 - 49) = A/(s-7) + B/ (s^2 - 49) + (C*s + D)/(s^2 - 49)
where A, B, C, and D are unknowns that you will find by matching coefficients.
S = (A(s^2-49) + B(s-7) + C*s + D) / (s-7) (s^2-49)
You can use this equation to solve for A, B, C, and D by matching coefficients.
-25-56/ (5+3) (s^2+ 16) - 2s - 56 / (s +3) (s^2 + 16) = A/(s-7) + B/(s^2 - 49) + (C*s + D)/ (s^2 - 49)

What is the appropriate liquid-to-flour ratio while baking muffins?The magic muffin ratio is 2:2:1:1. This equates to 2 parts flour, 2 parts liquid, 1 part fat, and 1 part eggs. The most crucial aspect is to remember to utilize the same unit of weight for each component!
Rinse frozen blueberries many times in cold water until the water turns lighter in color to prevent your batter and baked items from developing a purple-blue tint. Then, blot them dry with a paper towel and gently fold them into the batter. The goal of this procedure is to maintain fast breads light and delicate by limiting the quantity of gluten produced during the mixing process. To do this, the dry components are mixed in a one bowl, the wet ingredients are combined in a separate bowl, and then the two mixtures are combined together.

The average deviation of predicted DVD sales from the actual is 12.2279 million dollars. F-critical value is 4.0785>4.0785 we can reject the null hypothesis. The 95% confidence interval is (17.1536, 25.1554). The 95% prediction interval for the given value of x is (-3.8623, 46.1713).
Estimate the level of DVD sales for movies, by using the amount of annual revenue generated by the box office gross
We randomly selected a sample of 43 movies for the same year.
Excel α = 0.05, r^2 = 0.5123
=51.23%
51.23% of the DVD sales variation is explained by annual revenue.
SY.X = 12.2279.
Therefore, the average deviation of predicted DVD sales from the actual is 12.2279 million dollars.
b. The hypothesis being tested is:
Null Hypothesis, H0: β1 = 0
Alternative Hypothesis, H1: β1 ≠ 0
The test statistic, F = (6439.6133/1)/((12570.025 - 6439.6133)/(42 - 1)) = 43.07
The F-critical value is 4.0785.
Since 43.07 > 4.0785, we can reject the null hypothesis.
Therefore, we can conclude that there is a linear relationship between the revenues of DVD sales and the box-office gross.
c. y = bo + b1*x
y = 4.8445 + 0.1631*x
Put x = 100
y = 4.8445 + 0.1631*100 = 21.1545
The 95% confidence interval for the given value of x is:
= y ± t*s*[tex]\sqrt{0.026249}[/tex]
= 21.1545 ± 2.020*12.2279*[tex]\sqrt{0.026249}[/tex]
= (17.1536, 25.1554)
d. The 95% prediction interval for the given value of x is:
= y ± t×s×[tex]\sqrt{}[/tex]1 + hin [The t-value is calculated using =TINV(0.05,42-1) in Excel]
= 21.1545 ± 2.020*12.2279*[tex]\sqrt{1 + 0.026249}[/tex]
= (-3.8623, 46.1713)
Therefore, the value is (-3.8623, 46.1713).

3X + 1 i need help with this asp
Answer:
In algebra, the 3x + 1 semigroup is a special subsemigroup of the multiplicative semigroup of all positive rational numbers. The elements of a generating set of this semigroup are related to the sequence of numbers involved in the still open Collatz conjecture or the "3x + 1 problem".
