Point C is located at (1, 2), and point D is located at (-4,-2). Find the point that is the distance from point C
to point D. (1 point)
a. (-0.25, 1)

c. (-0.5, 1.5)
d. (0.25, 2.25)
Answer:
The answer would be c
Step-by-step explanation:
i choosed c because u have da negative sign in front of 4 and 2 and positive numbers with 1 and 2
Answer:
b
Step-by-step explanation:
I think this means to find the mid-point(?) of the line which by doing that you take both x-values and you add them and then divide by two, and then you take both y-values and add them and then divide by two. So you have: (1+-4)=-3, (-3/2)=-1.5
-1.5=x
(2+-2)=0, (0/2)=0
0=y
(-1.5, 0)

Find the missing quantity in the double number line.
The missing quantity is 100 books in the double number line.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other. Proportions are represented by the symbols "::" or "=".
Let the missing quantity be x in the double number line.
According to the given condition, we can write the proportion would be as:
40 books : 2 boxes = x books : 5 boxes
⇒ 40 / 2 = x / 5
Apply the cross-multiplication operation,
⇒ 40 × 5 = 2x
⇒ 2x = 200
⇒ x = 200/2
⇒ x = 100
Therefore, the missing quantity is 100 books in the double number line.

In ΔMNO, m = 89 inches, n = 30 inches and o=71 inches. Find the measure of ∠M to the nearest degree.
Answer:118
Step-by-step explanation:
Trust me
In triangle MNO, m = 89 inches, n = 30 inches and o=71 inches then the measure of ∠M is 118.7 degrees
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
To find the measure of angle ∠M, we need to use the law of cosines, which states that:
c² = a² + b² - 2ab cos(C)
To find ∠M, which is opposite to side m, so we can use the law of cosines as follows:
m²= n² + o² - 2no cos(∠M)
Substituting the given values, we get:
89² = 30² + 71² - 2(30)(71) cos(∠M)
Simplifying and solving for cos(∠M), we get:
cos(∠M) = (30²+ 71² - 89²) / (2(30)(71))
cos(∠M) = -0.4402
To find the measure of ∠M, we need to take the arccosine of cos(∠M) using a calculator:
∠M = 118.7 degrees
Hence, in ΔMNO, m = 89 inches, n = 30 inches and o=71 inches then the measure of ∠M is 118.7 degrees

A cheetah's speed was timed overa
100-yard distance. The cheetah was
(PLEASE HELP ME)clocked running 70 miles per hour. Which
equation shows the relationship between
the distance, y, and time, x, the cheetah
runs?
Answer:
y = 70x
Step-by-step explanation:
Note that d = rt where d is the distance, r is the rate/speed, and t is the time. Since we are given that the variable x is the time, 70mph is the speed, and the variable y is the distance, we can substitute these into d = rt, which we get y = 70x.

Jane is studying the weather in Alaska. She has recorded the temperature for four days in January, in degrees Fahrenheit, as shown in the table.
I have attached an image of the complete question.
Answer:
Options A & F are correct
Step-by-step explanation:
From the image attached, we have the following recorded temperature for 4 days in January.
Monday: -5° F
Tuesday: -1° F
Wednesday: 3° F
Thursday: 5° F
Option A is correct because the temperature on Monday and Tuesday is negative and thus below zero.
Option B is not correct because the temperature on Monday and Thursday are not the same since they are -5° F and 5° F respectively
Option C is not correct because the temperature on all days was not above zero since on Monday and Tuesday had negative temperatures
Option D is not correct because the lowest temperature below zero is on Monday and not Thursday
Option E is not correct because the temperature on Wednesday and Thursday are positive and not below zero.
Option F is correct because Monday had a temperature of -5° F which is the lowest gotten below zero
The temperature on Monday and Tuesday is negative and thus below zero.
The temperature on Monday had a temperature -5F which is the lowest value below zero.
Given,
Jane recorded temperature for 4 days in January.
Monday: -5° F
