Quadrilateral ABCD has vertices at A (0, 0), B (0, 3), C (5, 3), and D (5, 0). Find the vertices of the
quadrilateral after a dilation with scale factor 2.5.
Answers
According to the dilation formula, the location of the four vertices of the quadrilateral A'B'C'D' are A'(x, y) = (0, 0), B'(x, y) = (0, 7.5), C'(x, y) = (12.5, 7.5) and D'(x, y) = (12.5, 0).
How to determine the coordinates of the vertices of the dilated rectangle
Dilation are a kind of rigid transformations defined by the following formula:
P'(x, y) = O(x, y) + r · [P(x, y) - O(x, y)] (1)
Where:
O(x, y) - Center of dilationr - Dilation factorP(x, y) - Original pointP'(x, y) - Resulting pointIf we know that r = 2.5, O(x, y) = (0, 0), A(x, y) = (0, 0), B(x, y) = (0, 3), C(x, y) = (5, 3) and D(x, y) = (5, 0), then the resulting points are obtained:
A'(x, y) = (0, 0) + 2.5 · [(0, 0) - (0, 0)]
A'(x, y) = (0, 0)
B'(x, y) = (0, 0) + 2.5 · [(0, 3) - (0, 0)]
B'(x, y) = (0, 7.5)
C'(x, y) = (0, 0) + 2.5 · [(5, 3) - (0, 0)]
C'(x, y) = (12.5, 7.5)
D'(x, y) = (0, 0) + 2.5 · [(5, 0) - (0, 0)]
D'(x, y) = (12.5, 0)
Lastly, we proceed to graph the two figures.

How to compute the values?The total number of chocolate bars when there are 280 orange flavored bars will be:

Slope of AB = 4/3, Slope of BC = -2/7, Slope of CD = 4/3, Slope of AD = -2/7 and Quadrilateral ABCD is a parallelogram because both pairs of opposite sides are parallel.
How to find the slope of a quadrilateral?We are given the coordinates of the quadrilateral ABCD as;
A(−5, 1), B(−2, 5), C(5, 3), and D(2, −1).
Slope of AB = (5 - 1)/(-2 + 5) = 4/3
Slope of BC = (3 - 5)/(5 + 2) = -2/7
Slope of CD = (-1 - 3)/(2 - 5) = 4/3
Slope of AD = (-1 - 1)/(2 + 5) = -2/7
Thus we can see that both pairs of slope are equal which denotes that both pairs are parallel.

Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A F, B D, and C E. The length of line segment A G is 19 x + 14 and the length of line segment D G is 9 x + 2.
G is the centroid of triangle ABC.
What is the length of GF?
units
Answers
Based on the calculations, the length of GF is equal to 26 units.
How to find the length of GF?In Geometry, the centroid of any triangle always divides the lines in a ratio of 2:1. Thus, G divides line B F as follows:
2DG = BD
2(9x + 2) = 40
18x + 4 = 40
18x = 40 - 4
x = 36/18
x = 2.
Similarly, G divides line A F as follows:
2GF = A F
GF = A F/2
GF = (19x + 14)/2
GF = (19(2) + 14)/2
GF = 52/2
GF = 26 units.

Write a system of equations that represent the total fees charged for each plan. How many visits does it take before the plans are equal? Separate your equations and final number of visits by comas
Answers
The system of equation is y = 300 + 3x and y = 250 + 5x and the number of visits is 25
The system of equationsThe given parameters are:
Jim's Gym
Initial fee = $300Charges = $3 per visitSally's Salon
Initial fee = $250Charges = $5 per visitThe equation is calculated as:
Total (y) = Initial * Charges * Number of visits (x)
So, the system of equation is
y = 300 + 3x
y = 250 + 5x
Number of visits before the plans are equalWe have:
y = 300 + 3x
y = 250 + 5x
Substitute y = 300 + 3x in y = 250 + 5x
300 + 3x = 250 + 5x

Answers
The changes that transform C(t) to F(t) is that the function C(t) is stretched vertically to form the function F(t)
How to transform the function?The Fahrenheit function
The Celsius function is given as:
C(t) = -0.30 (t – 12)² + 40
The conversion from Celsius to Fahrenheit is
F(t) = 9/5 * C(t)
Hence, the Fahrenheit function is F(t) = 9/5 * C(t)
Convert values from Celsius to Fahrenheit
The values are t = 0, 12 and 24.
So, we have:
F(0) = -0.54(0 - 12)² + 72 = -5.76
F(12) = -0.54(12 - 12)² + 72 = 72
F(24) = -0.54(24 - 12)² + 72 = -5.76
The new function F(t)
The conversion from Celsius to Fahrenheit is
F(t) = 9/5 * C(t)
So, we have:
F(t) = 9/5 * (-0.30 (t – 12)² + 40)
Expand
F(t) = -0.54(t – 12)² + 72
Hence, the new function is F(t) = -0.54(t – 12)² + 72
The graph of function F(t)
See attachment for the graph of function F(t)
The changes that transform C(t) to F(t)
We have:
C(t) = -0.30 (t – 12)² + 40
F(t) = 9/5 * C(t)
The above implies that the function C(t) is stretched vertically to form the function F(t)

The test's degrees of freedom have been changed, which generally boosts the test's power for samples with unequal variance.
The means being equal is the test's null hypothesis.The notion that the means are not equal serves as the test's alternate hypothesis.Formula for Aspin Welch's T - test
The t-statistic in Aspin Welch's T-test is given as,

1. Taking your eyes off the road for ____ seconds at 60 miles per hour means you have traveled blindly for half the length of a football field.
Answers
Answer:
4.09 seconds
Step-by-step explanation:
simplify miles per hour to feet per second how many feet is a mile and how many seconds are in an hour you end up with 88 fps from 60 mph
now simply a football field is 360 feet so 360/88 is 4.09090909 etc
Your eyes off the road for 4.09 seconds.
What is speed?The rate of change of position of an object in any direction is called the speed.
Given that, Taking your eyes off the road for how many seconds at 60 miles per hour means you have travelled blindly for half the length of a football field,
Converting 60 mph into fps
60 mph = 88 fps
The length of a football field = 360 ft
Time = 350/88
= 4.09 seconds.
Hence, you travelled for 4.09 seconds.

In a New York State daily lottery game, a sequence of five digits (not necessarily different) in the range 0-9 are selected at random. Find the probability that four of the five digits are the same.
Answers
The probability that four of the five digits are the same is 0.036.
There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.

Question 10 How many cubic yards of sand will it take to fill a child's play area that measures 10 yards long, 8 yards wide, and 1/3 yard deep
Answers
Answer:
26.6 cubic yards
Step-by-step explanation:
Remark
What you have is a rectangle prism. It has an easy enough formula.
Formula
V = L *w * h
Givens
L = 10 yards
w = 8 yards
h = 1/3 yards
Solution
V = L*w*h
V = 10 * 8 * 1/3
V = 26.66 yds^3
What is the solution to the system of equations? "-6x2/5y=8" 1/2x+3y=29
(10, –2)
(10, 2)
(2, 10)
(–2, 10)
Answers
The answer choice which represents a solution to the system of equations is; (–2, 10).
Which answer choice is a solution to the systems of equations?The system of equations as given in the task content is;
-6x - (2/5)y = 8
(1/2)x +3y = 29
Hence, by making x subject in equation 1 and substitution; we have;
x = (-0.4y -8)/6
Hence; (0.4y -8)/12 + 3y = 29.
(0.4y -8) + 36y = 348
35.6y = 356
y = 10
and x = (-0.4(10) -8)/6 = -2.

Answers
Answer:
-40
Step-by-step explanation:
First you have to look at the difference between 8 and 10. which is 80, then because it takes two steps to go from 8 to 10 you divide 80 by two, which is 40. And because the values are decreasing it is -40.
