The midpoint of CD is M=(1, 2). One endpoint is C = (6, -2).
Find the coordinates of the other endpoint, D.
Answers
Answer: Endpoint = (-4,6)
Step-by-step explanation:
To find any endpoint use the formula [tex]\frac{x_1+x_2}{2} = Xmp[/tex] [tex]\frac{y_1+y_2}{2} =Ymp[/tex]
[tex]\frac{6+x_2}{2} = 1[/tex] [tex]\frac{-2+y_2}{2} =2[/tex]
multiply each by 2 to simplify
[tex]\frac{6+x_2}{2*2} = 1*2 = {6+x_2}= 2[/tex] [tex]\frac{-2+y_2}{2*2} =2*2 = -2+y_2=4[/tex] take the equations and simplify
6+[tex]x_{2}[/tex] = 2 -2+[tex]y_{2}[/tex] = 4 =
-6 -6 +2 +2
[tex]x_{2}[/tex] = -4 [tex]y_{2}[/tex] = 6
To check use the Midpoint formula
[tex]\frac{-4+6}{2} , \frac{6-2}{2} = \frac{2}{2} , \frac{4}{2} = (1,2)[/tex]

[tex]V=343\,\,cm^3[/tex]
Step-by-step explanation:
Recall that fractional exponents are other form of representing roots.
In our case, the formula for the volume of the cube in terms of area of a face, is also written as:
[tex]V=A^\frac{3}{2} =(\sqrt{A} )^3[/tex]
which for the case of a cube with face area of 49 cm^2 becomes:
[tex]V=(\sqrt{49} )^3=7^3=343\,\,cm^3[/tex]
Simplify each exponential expression using the properties of exponents and match it to the correct answer.

Answer:
-12, -21
Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.

Solution to the systems of equations,
g(x)=3x+2
f(x)=|x-1|+1
Answers
Hi there! :)
[tex]\large\boxed{\text{ x = 0, or (0, 2)}}[/tex]
The solution of g(x) = 3x + 2 and f(x) = |x - 1| + 1 is where the two lines intersect.
According to the graph, the functions intersect at the point (0, 2), or x = 0. This is the solution to the system of equations.
We could also prove this algebraically by setting the two equations equal to each other:
3x + 2 = | x - 1 | + 1
Assume the absolute value function is negative:
3x + 2 = -(x - 1) + 1
Simplify:
3x + 2 = -x + 2
Add x to both sides:
4x + 2 = 2
Subtract 2 from both sides:
4x = 0
x = 0. This is the solution to the system.
g(x)=3x+2 = 2/3
X = 0.6
f(x)=|x-1|+1 = no x intercept/0
Solve the equation
v-5/6=-7/8
Answers
add 20/24 to both sides: v=-1/24

Step-by-step explanation:
Answer:
2x^2 + 9x + 4
Step-by-step explanation:
To find the area of a triangle, use the formula, 1/2 · base · height = area.
If we plug the given expressions into the formula, we get
1/2(4x+2)(x+4)
Which simplifies to
(2x+1)(x+4)

Answers
Answer:
6 cm
Step-by-step explanation:
37 × 2 = 74 cm86 - 74 = 12 cm12 ÷ 2 = 6 cmSo, the width is 6 cmI hope this helps!
Answer:
The rectangle's width is 6.
Step-by-step explanation:
You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:
86 = 2(37) + 2w
86 = 74 + 2w
Subtract 74 on each side.
2w = 12
Then, divide each side by 2.
w = 6
Hopefully this helped. And good luck in your studies.

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?
Answers
Answer:
7 paddleboards
Step-by-step explanation:
In order to solve this, you have to find the total amount that they earned by renting surfboards.
To find this you multiply 55 x 51 =2,805.
Then you use this factor and subtract it from the total amount they earned.
$3,300 - $2,805 = $495.
This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.
495/70 = 7
In conclusion, they rented out 7 paddle boards.

. Suppose that 10 students of a class of 50 undergraduates are chosen for a behavioral experiment. The total class consists of 15 freshmen, 18 sophomores, 10 juniors, and 7 seniors. If all students are equally likely to be picked, determine the probability of the group contains exactly seven seniors and three juniors.
Answers
Answer:
Approximately 0% probability of the group contains exactly seven seniors and three juniors.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the students are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
7 seniors, from a set of 7.
3 juniors, from a set of 10. So
[tex]D = C_{7,7} \times C_{10,3} = \frac{7!}{7!(7-7)!} \times \frac{10!}{3!(10-3)&} = 1 \times 120 = 120[/tex]
Total outcomes:
10 students froms a set of 50. so
[tex]T = C_{50,10} = \frac{50!}{10!(50-10)!} = 10272278170[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{120}{10272278170} \approx 0[/tex]
Approximately 0% probability of the group contains exactly seven seniors and three juniors.
