Answer:
The coordinates of B are (10,2)
Step-by-step explanation:
Hi there!
We know that BC has a midpoint M, with the coordinates (6,6), and the endpoint C, with coordinates (2, 10)
We want to find the coordinates of point B
The midpoint formula is [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2 , y_2)[/tex] are points. In this case, the point C has the values of [tex](x_1, y_1)[/tex], and B has the values of [tex](x_2 , y_2)[/tex]
We know that coordinates of M equal [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex]
In other words,
[tex]\frac{x_1 + x_2}{2} = 6\\ \frac{y_1+ y_2}{2}=6[/tex]
Let's plug 2 for [tex]x_1[/tex] and 10 for [tex]y_1[/tex]
So:
[tex]\frac{2 + x_2}{2} = 6\\ \frac{10+ y_2}{2}=6[/tex]
Multiply both sides by 2
[tex]{2 + x_2} = 12\\{10+ y_2} =12[/tex]
Subtract 2 from both sides in the first equation to find the value of [tex]x_2[/tex]:
[tex]x_2=10[/tex]
Now, for the second equation, subtract 10 from both sides to find the value of [tex]y_2[/tex]
[tex]y_2=2[/tex]
Now substitute these values for [tex](x_2, y_2)[/tex]
[tex](x_2, y_2)=(10,2)[/tex]
So the coordinates of point B are (10, 2)
Hope this helps!

EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)
Answer:
After eight hours 6,561 people will know the rumor.
Step-by-step explanation:
Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:
Hour 0 = 1
Hour 1 = 1 + 2 = 3
Hour 2 = 3 + 2 x 3 = 9
Hour 3 = 9 + 2 x 9 = 27
Hour 4 = 27 + 2 x 27 = 81
Hour 5 = 81 + 2 x 81 = 243
Hour 6 = 243 + 2 x 243 = 729
Hour 7 = 729 + 2 x 729 = 2,187
Hour 8 = 2,187 + 2 x 2,187 = 6,561
Therefore, after eight hours 6,561 people will know the rumor.
Find the value of the ratio.

There are 336 different ways are there to present those ribbons if the order matters.
What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Eight students are competing for a blue, red, and yellow ribbon for their agriculture project.
Different ways are there to present those ribbons if the order matters.
By permutations, we have to calculate the number of different ways to arrange the ribbon is;
[tex]=3 \times 2\times 1\\\\=6[/tex]
Now, we have to calculate the different ways to choose 3 winners from 8 is;
[tex]=8\times 7\times 6\\\\=336[/tex]
Therefore, the correct option is (b), 336 ways are there to present those ribbons if the order matters.

Answer:
Number 1: 1 2/4 or 1 1/2
Number 2: 2 4/6
Number 3: 5/6
Step-by-step explanation:
For Numbers 1 and 2... You'd have to separate the whole number from the fraction and subtract accordingly.
Number 1: 2-1=1 and 3/4-1/4=2/4
So you would get 1 2/4.
Number 2: 3-1=2 and 5/6-1/6=4/6
You would get 2 4/6
For Number 3 you would have to find the LCD (Least common denominator) for 1/2 and 2/3.
The answer will then be 5/6.
(I couldn't solve number 4 because it wasn't visible.)

300% of what number is 75?.
Answer:
25
Step-by-step explanation:
Find the number by dividing 75 by 3, since 75 is the number tripled.
75/3
= 25
So, 300% of 25 is 75.
Answer:
25
Step-by-step explanation:
300% * x = 75
300/100 * x = 75
x = 75 * 100/300
x = 25
Evaluate: 19 - 3k] = 3
Answer:
k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]
Step-by-step explanation:
|19 - 3k| = 3
-3k = 3 - 19
-3k = -16
k = 16/3
k = 5 1/3
-19 + 3k = 3
3k = 3 + 19
3k = 22
k = 22/3
k = 7 1/3
The function f(x) = |x| is shifted to the left 3 units and down 2 units to make the function g(x) . Write the equation g(x) that illustrates this change.
Answer:
g(x) = |x+3|-2
Step-by-step explanation:
to move horizontally replace each x with (x ± c)
if you move it to the right, you need x - c
if you move it to the left , you need x + c
so , since we are moving 3 units to the left, we replace the x with x+3
g(x) = |x+3|-2

Answer:
[tex]\sqrt{28}[/tex]
Step-by-step explanation:
It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,
[tex](a)^2+(b)^2=(c)^2[/tex]
Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,
[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]
