Which of the following transformations will always produce a congruent figure?
A. reflection
B. dilation
C. expansion
D. contraction
Which of the following transformations will produce a similar, but not congruent figure?
A. dilation
B. translation
C. reflection
D. rotation

Answers

Answer:

A, d

Step-by-step explanation:

A) reflection, A) dilation

Step-by-step explanation:

To produce a congruent figure, the angle measures of the image and the side lengths of the image must be the same as the angle measures and side lengths of the pre-image. This means we cannot shrink, expand, or contract the figure; by definition, those transformations change the size. This leaves reflection.

To produce a similar, but no congruent figure, we must change the side lengths while keeping the angle measures preserved. Translations, reflections and rotations will move a figure but do not change the side lengths; dilation is the only choice that will change the side lengths.

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 20.8 years; the
standard deviation is 3.1 years.
Use the empirical rule (68 – 95 - 99.7%) to estimate the probability of a gorilla living between 11.5 and 27 years.

Answers

If the mean is 20.8, one standard deviation each way is adding and subtracting 3.1, so 17.7 and 23.9 (68% of values)

Two standard deviations adding and subtracting 3.1*2 = 6.2, or 14.6 and 27.

Three standard deviations is 11.5 and 30.1

So we have
11.5 - 14.6 - 17.7 - 20.8 - 23.9 - 27 - 30.1

Going left to 11.5 is 3 standard deviations out, so 99.7/2 = 49.85%

Going right to 27 is 2 standard deviations out, so 95/2 = 47.5%

Add those two % to get 97.32%

The cylinder shown here has a height of 7 centimeters and a radius of 4 centimeters.
Part A. What is the area of the base of the cylinder? Express your answer in terms of π. options are: 15 pi cm, 14 pi cm, 16 pi cm, 17 pi cm.

Part B: How many cubic centimeters of fluid can fill this cylinder? Express your answer in terms of π. options are: 112 pi cm, 110 pi cm, 113 pi cm, 107 pi cm.

Part C: Give a decimal approximation of your answer to the second question using 3.14 to approximate π. options are: 351.68 cm, 368.15 cm, 386.51 cm, 315.68 cm.

Answers

Answer:

A: 16[tex]\pi[/tex][tex]cm^{2}[/tex]

B: 112[tex]\pi[/tex][tex]cm^{3}[/tex]

C: 351.68[tex]cm^{2}[/tex]

Step-by-step explanation:

The cubic inches that can fill the cylinder is [tex]112\pi[/tex] and the decimal approximation 351.68 cm^3

The given parameters are:

Radius (r) = 4 cm

Height (h) = 7 cm

The area of the base

The area of the base is:

[tex]A = \pi r^2[/tex]

So, we have:

[tex]A = \pi *4^2[/tex]

[tex]A = 16\pi[/tex]

Hence, the area of the base is [tex]16\pi[/tex]

The cubic inches that can fill the cylinder

This is the volume of the cylinder.

So, we have:

[tex]V = \pi r^2h[/tex]

Substitute known values

[tex]V = \pi * 4^2 * 7[/tex]

[tex]V = 112\pi[/tex]

Hence, the cubic inches that can fill the cylinder is [tex]112\pi[/tex]

The decimal approximation

We have:

[tex]V = 112\pi[/tex]

Expand

[tex]V = 112 * 3.14[/tex]

Evaluate the product

[tex]V = 351.68[/tex]

Hence, the cubic inches that can fill the cylinder is 351.68 cm^3

Answer:

20 is the total perimeter

Step-by-step explanation:

Answer:

6x + 2

Step-by-step explanation:

The area of a square is side length times itself.

In this problem, the area of one square is:

x², or x * x. So the side length of each square must be x.

In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).

Plugging that into the equation, top * x = x, so the top must be 1.

There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".

Substitue the values of each side.

5x + 1 + 1 + x = 6x + 2

Hope this helps! If you have any questions, feel free to ask.

Answer:

The graph is not a function.

Step-by-step explanation:

Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.

7/8 x 3/5 simplified

Answers

Answer:

21/40

Step-by-step explanation:

First you multiply the numerators (7 & 3) to get 21, then denominators (8 & 5) to get 40, unfortunately it cannot be reduced

In the scenario that it could be reduced, I was taught to cross reduce. lets say we had 2/8 x 4/6

You could divide by four for the 8 (denominator) and 4 (numerator) getting you 2/4 and 1/6

Then you do the same thing for 2 (numerator) and (6 denominator) so 2/2 is 1 and 6/2 is 3

Leaving you with 1/4 x 1/3 making it easier to multiply, and you don't have to reduce! Hope this helps!!

y = 2x - 10

C)
y =1/2x + 5/2

Answers

Answer:

D

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

4 - 2 / 3 - (-1) = 2/4 = 1/2

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2
