Answer:
Hi there!
The following answers are:
14: to determine whether or not the slopes are perpendicular to one another is the negative reciprocal. In other words, if the first slope is m, the perpendicular slope is -1/m
to determine whether or not the slopes are parallel, the slopes are the same. In other words, if the first slope is m, then the parallel slope is m
So in other words: 1. perpendicular 2. neither 3. perpendicular 4. parallel
15: There are four types of rigid motions that we will consider: translation , rotation, reflection, and glide reflection.
16: Dilation is the transformation that changes the size of a figure.
Answer:
13. It says 13c so I am thinking there was 13a and 13b so I can't really answer that.
14.
1. perpendicular.
2.parallel.
3. neither.
4. parallel.
15. rotation, reflection, glide reflection and translation.
16. dilation.
Step-by-step explanation:
#14 you just need to use numbers to figure it out. for example 1. lets say the starting point is (0,2) m=3 you will go 3 squares up and one square right and end up at (5,1) but where for m=-1/3 you will go 1 square down and three squares right. You can do this until you have lines and see from the image you get whether it is perpendicular, parallel or neither.
#15 and 16 this are what I think are the answers but try checking it out online too. You might find the answers you are looking for there.

Answers
Answer:
6 years and 15 years of age
Step-by-step explanation:
Given the ratio of their ages is 2 : 5 = 2x : 5x ( x is a multiplier )
Then in 9 years their ages are 2x + 9 and 5x + 9 in the ratio 5 : 8
By proportion
[tex]\frac{2x+9}{5x+9}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )
5(5x + 9) = 8(2x + 9) ← distribute parenthesis on both sides
25x + 45 = 16x + 72 ( subtract 16x from both sides )
9x + 45 = 72 ( subtract 45 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
Thus
Rohit's age = 2x = 2( 3) = 6
James' age = 5x = 5(3) = 15
6 : 15 = 2 : 5
How many 2-letter combinations can be created from the distinct letters in the word "mathematician"? Assume that the
order of the letters does not matter.

Answers
Answer:
Option A.
Step-by-step explanation:
The given word is "mathematician".
Here, total number of letter is 13 and
Number of distinct letters = 8
We need to select 2 distinct letters from word "mathematician".
It means we need to select 2 letters from 8 distinct letters.
Total ways [tex]=^8C_2[/tex]
[tex]=\dfrac{8!}{2!(8-2)!}[/tex]
[tex]=\dfrac{8\times 7\times 6!}{2\times 6!}[/tex]
[tex]=28[/tex]
Therefore, the correct option is A.

Answer:
∠ A = 31.3°, ∠ C = 58.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{25}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{13}{25}[/tex] ) ≈ 31.3° ( to the nearest tenth )
The sum of the 3 angles in a triangle = 180° , thus
∠ C = 180° - (90 + 31.3)° = 180° - 121.3° = 58.7°

dilation
reflection
rotation
stretch
translation
Answers
Answer:
Reflection, rotation and translation
Step-by-step explanation:
By definition, a rigid transformation is a transformation that preserves length.
Dilation and stretch change the measure of the figure, and then, they are not rigid transformations.
On the other hand, reflection, rotation and translation don't change the measure of the figure, only change its position and orientation, so, they are rigid transformations.
Reflection, translation, dilation are rigid transformations.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Rigid transformations is a transformation that preserves the shape and size of the figure. Types of rigid transformation are reflection, translation, dilation.

Tina has 13 cups of water to divide evenly among 7 plants. which of the following best approximates the number of cups of water that each plant will get ?
1/2, 1, 1 1/2, 2, 2 1/2
Answers
Answer:
Option d, 2 cups.
Step-by-step explanation:
Tina has the number of cups of water = 13
She has to divide evenly among the number of plants = 7
The number of cups of water that each plant will get
= [tex]\frac{13}{7}[/tex] cups
= [tex]1\frac{6}{7}[/tex] cups
= 1.857 ≈ 1.9 cups
among the given 4 option, best approximates the number of cups would be 2 cups.
Option d, 2 cups.

Answers
Hi!
I'm Happy to help you today!
The answer to this question would be 30!
This is because to find the mean you have to add everything up, then divide it by how many number's there are so for this problem it is:
30 + 45 + 25 + 25 + 35 + 5 + 40 + 35 + 40 + 20 = 300
Then Divide!
300 ÷ 10 = 30
So 30 is your answer!
