1. a. The image's dilated side lengths on each side:
AB = CD = 45cm.
BD = AC = 24cm.
2. a. Equal ratios exist between the lengths of matching sides. The ratio is the same as the dilation's scale factor.
b. The image is a dilation of the original image.
c. The scale factor = 4.
3. a. The image is a dilation of the original image.
b. The scale factor = 2.
What do you mean by scale factor?A scale factor, often referred to as a conversion factor, is a numerical value that is used to alter a figure's size without altering its shape. The scale factor can be calculated if both the dimensions of the original and the dilated (increased or lowered) figure are known. The basic formula for calculating a figure's scale factor is given as,
Scale factor is equal to the division between the dimensions of the new and old shapes.
In the first figure, the sides are given as:
AB = 15cm
BD = 8cm
Scale factor = 3
Now, using the scale factor formula:
Scale factor = New dimensions/Old dimensions
⇒ 3 = New dimension/15
⇒ New dimension of AB = 45cm.
Similarly, new dimension of BD = 24cm.
In the second figure, as the lengths of corresponding sides have equal ratios. Both the figures are similar. The image is the dilation of the original figure as the lengths of corresponding sides have equal ratios. The ratio is the same as the dilation's scale factor. So, the scaler factor here is 4.
Now in the last figure we can see that the coordinates of A', B', C' and D' are exactly half of that of the coordinates of A, B, C and D.
The ratio of the coordinates is 2:1.
Therefore, the scale factor = 2.

Since multiplication is implied algebra we often don't need to actually write the times symbol ‘×'. Re-write this algebraic equation without the times symbol. a × b = 4 × c
Answer:
ab=4c
Step-by-step explanation:
Since a and b are being multiplied, we can just right ab. Since 4 and c are being multiplied, we ca just right 4c.
Answer:
ab=4c
Step-by-step explanation:
Basically, if you see any variables that are together like that or numbers side by side with letters, it means it's just being multiplied! This doesn't however, work with numbers next to numbers. So for example:
Say you have a x b = 5 x 5c
It would be ab = 5 x 5c Because only letters get put next to each other. That's really the only way I know how to explain it. Have a great day and good luck!

Bacteria are the most common example of exponential growth. Select a number between 2 and 10 to represent the hourly growth rate of a certain bacteria. For example, selecting the number 8 would mean that the amount of bacteria will be 8 times greater after every hour.
a. Suppose you start with one single bacterium. Make a table of values showing the number of bacteria that will be present after each hour for the first six hours using the hourly growth rate that you selected. Then determine how many bacteria will be present once 24 hours have passed.
b. Explain why this table represents exponential growth.
c. Using this example, explain why any nonzero number raised to a power of zero is equal to one.
d. Write a rule for this table.
e. Suppose you started with 100 bacteria, but they still grew by the same growth factor. How would your rule change? Explain your answer.
Answer:
bh
Step-by-step explanation:
Answer:
Answers are below
Step-by-step explanation:
Hour 0 1 bacterium
Hour 1 3 bacterium
Hour 2 9 bacterium
Hour 3 27 bacterium
Hour 4 81 bacterium
Hour 5 243 bacterium
Hour 6 729 bacterium
After 24 hours, the number of the bacterium will reach 282,429,536,481.
B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.
C) The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
D) Y = 1 + 3 to the power of x
E) The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.

The sides of a triangle are in the extended ratio of 3 : 4:10. If the length of the
shortest side is 9 in., what is the perimeter of the triangle?
Answer:
51cm
Step-by-step explanation:
9 divided by 3 is 3inches
3 inches is 1 share
3 plus 4 plus 10 is 17
17 times 3 is 51
The length of the triangle is 9, 12, and 30. Then the perimeter of the triangle will be 51 inches.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The perimeter of the triangle is determined by adding together all of its sides.
The sides of a triangle are in the extended ratio of 3:4:10. If the length of the shortest side is 9 in.
Let x be the canceled value from the ratio. Then we have the ratio will be 3x: 4x: 10x.
The value of the variable 'x' is given as,
3x = 9
x = 9 / 3
x = 3
Then the other sides of the triangle will be
4x = 4 (3) = 12 in
10x = 10 (3) = 30 in
Then the perimeter of the triangle will be calculated as,
P = 9 + 12 + 30
P = 51 inches
The length of the triangle is 9, 12, and 30. Then the perimeter of the triangle will be 51 inches.

Which best describes the shape of this distribution?
O A. Bimodal symmetric
B. Bimodal skewed
O c. Uniform
O D. Unimodal skewed
O E. Unimodal symmetric
The given histogram is unimodal skewed.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
This histogram is unimodal skewed.
There are two parts to this answer. The first part has to do with the number of modes.
This would be the item that is occurring the most frequently. In this case the mode is only 4.
It is occurring more than any other.
The second part of this has to do with the distribution of the data as it is displayed on the histogram.
There are 4 pieces of data that are only occurimg one time on the right of the histogram. We call this skewing the data.
When both sides looks almost the same we say it is symmetric.
Hence, the given histogram is unimodal skewed.

If t represents the amount of time Neda has spent typing the second letter, which equation states the rule used to determine the number of words, W, Neda has typed today?
Answer:
W = t + 200
Step-by-step explanation:
Number of words typed in the first letter = 200
The relationship between the total words typed, W and the number of seconds, t spent on the second letter :
W = number of words typed in first letter + t
W = 200 + t
Choosing any pair of values from the table :
W = 245 ; t = 45
W = 200 + 45
W = 245
Therefore, the number of words, W typed today can be represented as
W = 200 + t

if a cone has a volume of 28.63 and a diameter of 4.5 what is the height
Answer:
height = 5.4 units
Step-by-step explanation:
r = 4.5/2 = 2.25
B = πr² = 3.14(2.25²) = 15.90
V = 1/3Bh
28.63 =1/3(15.90)h
85.89 = 15.90h
