A parallelogram has vertices (5,0), (3, -3), (-4, -3) and (-2, 0) The
diagonals of the parallelogram intersect at their midpoints. A. What are the coordinates of the
intersection of their diagonals? Justify the answer algebraically.
Answer:
(0.5 , -1.5)
Step-by-step explanation:
intersection of their diagonals (E): right at the mid-point of segment AC or BD
A (5 , 0) and C (-4 , -3): E (x , y)
x = (5 + -4 ) / 2 = 0.5
y = (0 + -3 ) / 2 = - 1.5
E ( 0.5 , - 1.5)
check with BD: x = (3 + -2) / 2 = 0.5 y = (-3 + 0) / 2 = - 1.5
determine the missing angle
Answer:
46°
Step-by-step explanation:
These angles are same-side supplementary, therefore they add up to 180°.
180 - 134 = 46°.

Answer:
x = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let the third side be x , then
x² + 8² = 10²
x² + 64 = 100 ( subtract 64 from both sides )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6
Answer:
6
Step-by-step explanation
Ordered triples only apply to right triangles
3,4,5 is an ordered triple
multiply (3,4,5) by 2 and you get (6,8,10)
the 2 other side lengths are 8 and the hypotenuse is 10 then the other side length is 6.
-------------------
That is just a way to do it quickly and it does not always apply.
the formula for Pythagorean and theorem is a^2+b^2=c^2
a=leg of the triangle
b=other leg of teh triangle
c=hypotenuse(longest leg)
as we can see here 10 is the longest so it is the hypotenuse.
So then we can assume that 8 is a leg of the triangle
so we insert that into the equation
a^2+8^2=10^2
subtract 8^2 from both sides
a^2=10^2-8^2
a^2=100-64
a^2=36
square root both sides
a=√(36)
a=6
Hope that helps :)
Explain why this quadrilateral is not a parallelogram.
Answer:
opposite sides aren't equal
Answer: For a quadrilateral to be considered a parallelogram all opposite sides must be equal, however the shape shown in the image above does not meet this condition as all sides are a different size.
Fill in the missing numbers
I need an answer ASAP
Answer:
the missing numbers be 60 and 6 respectively
Step-by-step explanation:
The computation of the missing numbers are shown below:
Let us assume the missing numbers be x
a/
, [tex]\frac{1}{2} \times 30 = \frac{1}{4} \times x\\\\15 = \frac{1}{4} \times x\\\\x = 60[/tex]
b.
[tex]\frac{1}{3} \times 12 = \frac{2}{3} \times x\\\\4 = \frac{2}{3} \times x\\\\x = 6[/tex]
Hence, the missing numbers be 60 and 6 respectively

A repairman leans the top of an 26 foot ladder against the
top of a stone wall. The base of the ladder is 4.7 feet from
the wall. How tall is the wall? (Use Pythagorean Theorem:
a² + b2= c2)
Answer:
26.42139285
Step-by-step explanation:
26x26 + 4.7x4.7 = c2
676 + 22.9 =c2
698.09=c2
square root of 698.09=26.42139285
26.42139285 = c

+(-8) = 2
X =
Answer:
x = 10.
Step-by-step explanation:
x + (-8) = 2.
First, isolate x by adding 8 to both sides.
x = 8 + 2.
Next, solve.
x = 10.
Finally, you can come to the conclusion that x = 10. Always plug in your answer to make sure it works.
10 - 8 = 2.
2 = 2.
help please!! ill mark brainliest
Answer:
∠ B = 54°
Step-by-step explanation:
The angles are supplementary, that is they sum to 180° , then
7x + 14 + 5x - 26 = 180 , that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Then
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°

Answer: 32
Step-by-step explanation: ok so here is what i do for those I grab a caculator (desmos online caculator i like to use but not required) then ill do (1/2×x)+4 but then once i write that i go back to the x delete the x and keep putting random numbers in higher and higher by one till the i get the answer (example: for this one i wrote that than i removed the x in it and did 1/2×5+4 then when that did not equal 20 i turned the 5 into a 6 then 6 was wrong so 7, then 8, then i just skipped to 20 then 20 was still wrong so skipped to 30, 30 was also wrong but CLOSE so then i tried 31 then 32 till the answer was 20 and when i did 32 it did say 20) hopes this helps

Answer:
f(x) = 2ˣ + 1
Step-by-step explanation:
Based on the exponential increase, you know that it will be an exponential equation, meaning that you can cancel out the first two options.
The easiest way to do pick the between the two remaining equations is by plugging in an x-value and seeing if the y-value for that equation matches the y-value from the equation.
For (3, 9):
f(x) = 3ˣ = 3³ = 27
f(x) = 2ˣ + 1 = 2³ + 1 = 8 + 1 = 9
The last equation is the equation that is represented by the table.

Nancy’s rectangular garden has a diagonal of 18.4 feet and a width of 7 feet. If she needs to paint the floor, how much area is she going to cover?
Answer:
17
Step-by-step explanation:
The computation is shown below:
Here we applied the pythagoras theroem
Given that
Diagonal of 18.4 feet
Width of 7 feet
So, the area would be
= 18.4^2 - 7^2
= 17
