CAN SOMEONE PLS ANSWER-If W(- 10, 4), X(- 3, - 1) , and Y(- 5, 11) classify AEXY by its sides . Show all work to justify your answer
Answers
Answer:
WX = [tex]\sqrt{74} \approx 8.6023253\\\\[/tex]XY = [tex]2\sqrt{37} \approx 12.1655251\\\\[/tex]WY = [tex]\sqrt{74} \approx 8.6023253\\\\[/tex]Classify: Isosceles============================================================
Explanation:
Apply the distance formula to find the length of segment WX
W = (x1,y1) = (-10,4)
X = (x2,y2) = (-3, -1)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-3))^2 + (4-(-1))^2}\\\\d = \sqrt{(-10+3)^2 + (4+1)^2}\\\\d = \sqrt{(-7)^2 + (5)^2}\\\\d = \sqrt{49 + 25}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\[/tex]
Segment WX is exactly [tex]\sqrt{74}[/tex] units long which approximates to roughly 8.6023253
-------------------
Now let's find the length of segment XY
X = (x1,y1) = (-3, -1)
Y = (x2,y2) = (-5, 11)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-(-5))^2 + (-1-11)^2}\\\\d = \sqrt{(-3+5)^2 + (-1-11)^2}\\\\d = \sqrt{(2)^2 + (-12)^2}\\\\d = \sqrt{4 + 144}\\\\d = \sqrt{148}\\\\d = \sqrt{4*37}\\\\d = \sqrt{4}*\sqrt{37}\\\\d = 2\sqrt{37}\\\\d \approx 12.1655251\\\\[/tex]
Segment XY is exactly [tex]2\sqrt{37}[/tex] units long which approximates to 12.1655251
-------------------
Lastly, let's find the length of segment WY
W = (x1,y1) = (-10,4)
Y = (x2,y2) = (-5, 11)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-5))^2 + (4-11)^2}\\\\d = \sqrt{(-10+5)^2 + (4-11)^2}\\\\d = \sqrt{(-5)^2 + (-7)^2}\\\\d = \sqrt{25 + 49}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\[/tex]
We see that segment WY is the same length as WX.
Because we have exactly two sides of the same length, this means triangle WXY is isosceles.

Answers
Answer:
the perimeter is 960
Step-by-step explanation:
The computation of the perimeter is shown below;
If we assume
= (24 × 2) + (6 × 2)
= 48 + 12
= 60
And, the area is 16 times to that of original So
= 60 × 16
Hence, the perimeter is 960
You deposit $750 in a bank
account that will earn a simple
interest of 3.5% per year.
How much will your investment
be worth after 12 years?
Answers
Answer:
$1,065
Step-by-step explanation:
Simple interest equation: A=P(1+rt)
P (principal amount) = 750, r (rate) = 3.5%, t (time) = 12 years
A=750(1+(3.5)(12))
A=1065
The amount of an investment to be worth after 12 years should be considered as the $1,065
Calculation of an investment:Since
The deposited amount is $750
The rate of interest is 3.5% per year.
And, the time period is 12
So,
A=750(1+(3.5)(12))
A=1065
Hence, The amount of an investment to be worth after 12 years should be considered as the $1,065

Answer:
(a) A'(-2, 1), B'(-4, -3), C'(-7, 0)
Step-by-step explanation:
If X is the center of rotation, the coordinates of point P are transformed like this:
P' = -(P -X) +X
P' = 2X -P
(x, y) ⇒ (2(-5) -x, 2(3) -y)
(x, y) ⇒ (-10-x, 6-y)
__
Your points are transformed to ...
A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)
B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)
C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)
These coordinates match the first choice.
The volume of a cube related to the area of a face by the formula V =A^3/2. What is the volume of a cube whose face has an area of 25mm^2.
Answers
Answer:
Volume = 125 mm^3
Step-by-step explanation:
Here, we want to get the volume of the cube
What we have to do here is to substitute the value of the area
We have this as
:
V = 25^(3/2)
V = (√25)^3
V = 5 * 5 * 5 = 125 mm^3

After 5 years, the sum of the ages of Reema and Neha will be 30. If Reema is 4 years
younger than Neha today, then find the sum of the present ages of Reema and Neha.
years
Answers
Answer:
Sum of their present ages = 20 years
Step-by-step explanation:
Present age :
Neha's age = x years
Reemas' age = x - 4
After 5 years:
Neha's age = (x +5) years
Reemas' age = (x - 4 + 5 ) = x + 1
Sum of the ages of Reema and Neha will be 30
Therefore,
x + 5 + x + 1 = 30
x + x + 5 + 1 = 30
2x + 6 = 30
2x = 30 - 6
2x = 24
x = 24/2
x = 12
Neha's age = 12 years
Reema's age = 12 - 4 = 8 years
Sum of their present ages = 12 + 8 = 20 years

[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
We have,
x₁ = -2, y₁ = 8, x₂ = 10 and y₂ = 6
So,
[tex]M=(\dfrac{-2+10}{2},\dfrac{8+6}{2})\\\\=(\dfrac{8}{2},\dfrac{14}{2})\\\\=(4,7)[/tex]

You have $3.10 in dimes and quarters.You have 3 more dimes than quarters. write an equation that relates the number of coins and have any equation for the value of the coins.how many of each kind of coin do you have?
Answers
Answer:
y=Q+3D
Step-by-step explanation:
the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,
0.10x + 0.25y = 3.10 ...1
x = y + 3 ...2
From equations 1 and 2, then we have
0.10(y + 3) + 0.25y = 3.10
0.10y + 0.30 + 0.25y = 3.10
0.35y = 2.8
y = 8
Then the value of 'x' is given as,
x = 8 + 3
x = 11
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
