What are the coordinates of vertex B' if the figure is rotated
90° counterclockwise about the origin?
Answers
Answer:
Answer: B'(-5,2)
Step-by-step explanation:
Rotations
When rotating a point B(x,y) 90 degrees counterclockwise about the origin it maps to an image point B'(-y,x).
The image shows a figure formed by points ABCD. The coordinates of B are B(2,5).
This point will be rotated 90 degrees counterclockwise about the origin, thus the coordinates of the image point B' are B'(-5,2).
Answer: B'(-5,2)

Answers
Answer:
C. r = 3 - cos theta
Step-by-step explanation:
The other user who answered was correct.
The equation is belongs to the graph of the limacon curve is r = 3 - cos [tex]\theta[/tex]
The correct option is C.
At θ = 180°, the value of r is positive, but just a fraction of the value at
θ = 0°. This eliminates choices 'b' and 'd'.
As, the equation of a horizontal cardiod is r= a ± a cos θ.
Here, from the figure we have horizontal cardiod.
Then, the equation is belongs to limacon curve is r = 3 - cos [tex]\theta[/tex].

Answers
Answer:
2000 eels
Step-by-step explanation:
Let us represent the total estimate of the eels = x
She returns the 50 eels to the lake.
The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.
To solve the above question, we have the following:
50/x = 10/400
Cross Multiply
10x = 50 × 400
x = 50 × 400/10
x = 2000 eels
Therefore, the total estimate of the eels in the lake = 2000 eels

(50 POINTS HELP)The manager of a restaurant chain wants to know how many times per month diners come to his restaurant. The table shows the number of visits in one month for three samples of 10 randomly chosen diners.

Write your answer in the space below.
The mean of sample 1 =

3. Based on the data, would you predict that, in one month, the average diner would visit the restaurant fewer than 3 times, 3 or 4 times, or, about 4 times? Explain your reasoning.
Write your answer in the space below.
Answers
Answer:
Means
sample 1: 3.6
sample 2: 3.3
sample 3: 3.8
Step-by-step explanation:
Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four
a) The mean of the sample 1 = 3.6
b) The mean of the sample 2 = 3.3
c) The mean of the sample 3 = 3.8
d) In one month, the average diner would visit the restaurant 3 or 4 times
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the sample 1 be represented as M₁
Let the mean of the sample 2 be represented as M₂
Let the mean of the sample 3 be represented as M₃
where the number of visits to restaurant in one month is given by
Sample 1 = { 5 , 2 , 6 , 4 , 4 , 7 , 2 , 1 , 2 , 3 }
The number of visits = 10 visits
The total sum of sample 1 = 36
So , mean M₁ = 36/10 = 3.6
And , Sample 2 = { 2 , 6 , 1 , 3 , 4 , 5 , 2 , 1 , 5 , 4 }
The number of visits = 10 visits
The total sum of sample 1 = 33
So , mean M₂ = 33/10 = 3.3
And , Sample 3 = { 3 , 3 , 6 , 4 , 1 , 5 , 3 , 4 , 4 , 5 }
The number of visits = 10 visits
The total sum of sample 1 = 38
So , mean M₃ = 38/10 = 3.8
And , the average diner would visit the restaurant 3 or 4 times because the mean value of the three samples lies between 3 and 4
Hence , the mean of the sample is solved

(6x - 3) - (-3x + 2)
Answers
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333

Answers
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
[tex]7 = 2x + 1[/tex]
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
[tex]6 = 2x[/tex]
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
[tex]3 = x[/tex]
