Is the figure shown in the xy-coordinate plane a parallelogram? Why or why not? Use the given coordinates to justify your answer.
The figure shown would represent a parallelogram if opposite sides are parallel and congruent
It is true that the figure is a parallelogram
How to determine if the figure is a parallelogram
The coordinates of the figure are given as:
O = (0,0)
P = (a,b)
S = (a + c,b)
T = (c,0)
Vertices O and T are on the same horizontal level, because they have the same y-coordinate
The above is also applicable to vertices P and S
By observation, we have the following distances:
PS = c
OT = c
This means that the opposite sides are parallel and congruent
Hence, the figure is a parallelogram

There are 40 monkeys and 60% of the monkeys are in the trees. How many monkeys are in the trees?
Show your work: Write an equation, solve and explain your thinking
Answer:
24 monkeys are in the tree
Step-by-step explanation:
We solve it by writing [tex]\frac{60}{100}[/tex] times [tex]\frac{40}{1}[/tex]
Why is it over 100? Because every percent is out of 100!
[tex]\frac{60}{100}[/tex] X [tex]\frac{40}{1}[/tex] (your equation)
60 times 40 = 2400 and 100 times 1 = 100, We get, [tex]\frac{2400}{100}[/tex],
Lastly, we simplify the fraction by 100 on each side:
[tex]\frac{2400}{100}[/tex] / [tex]\frac{100}{100}[/tex]
you get 24

Which derivation correctly uses the cosine sum identity to prove the cosine double angle identity
Answer: A
Step-by-step explanation: took the test
The derivation that correctly uses the cosine sum identity to prove the cosine double angle identity is A; cos²(x) - sin(x)²
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Let revise the identities of double an angle
sin(2x) = 2 sin(x) cos(x)
cos(2x) = cos²(x) - sin²(x)
cos(2x) = 2 cos²(x) - 1
cos(2x) = 1 - 2 sin²(x)
The equation
∵ cos(2x) = cos(x + x)
cos(x)cos(x) - sin(x)sin(x)
cos²(x) - sin(x)²
The identity is cosine double angle identity for cosine difference

Line A is represented by the equation, y=1/4x +5
(a) Write in slope-intercept form the equation of a line that is parallel to Line A and passes through the point, (8, -2). Show your work
(b) Write in slope-intercept form the equation of a line that is perpendicular to Line A and passes through the point, (4,1). Show your work.
Answer:
(a) y = 1/4x - 4
(b) y = -4x + 17
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
(a)
Parallel lines have the same slope but different y-intercepts.
m = 1/4x
y = 1/4x + b
-2 = 1/4(8) + b
-2 = 2 + b
b = -4
y = 1/4x - 4
(b)
Perpendicular lines have the negative reciprocal slope.
m = -4
y = -4x + b
1 = -4(4) + b
1 = -16 + b
b = 17
y = -4x + 17
Answer:
(a) y = 1/4x - 4
(b) y = -4x + 17
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Parallel lines have the same slope but different y-intercepts
Perpendicular lines have the negative reciprocal slope.
Jim made $143 for 11 hours of work at the same rate how many hours would he have to work to make $91
Answer:
Step-by-step explanation:
The equation is
Salary = 11 * x Where x is the number of hours.
salary = 143
hours = 11
x = ?
143 = 11x Divide both sides by 11
143/11 = 11x/11
13 = x
So to get 143 he works for 13 dollars / hour
salary = 13 * x
salary = 91
13 x = 91
13x/13 = 91/13
x = 7
He must work 7 hours to get 91 dollars.
Jim made 143 dollar for 11 hours of work at the same rate how many hours would he have to work to make 91 dollar
✺ Explanation -:Given:
Jim made $143 for 11 hours of work.To Find:
Hours he have to work to make $91.Solution:
We can solve this question using two methods Unitary Method and Method of proportion.
Unitary Method -
For $143 he work 11 hours
For $1 he work [tex]\dfrac{11}{143}[/tex] hrs
For $91 he works [tex]\dfrac{\cancel{11}} {\cancel{143}\: \: \cancel{13}}[/tex] × [tex]\cancel{91}\: \: 7 [/tex]hrs
= 7 hours
He must work 7 hours to get $91.
[tex] \ {\rule{50mm}{3pt}}[/tex]
Method of proportion -
He work 'x' hours for $91. (x as no. of hrs)
[tex] \left[\begin{array}{c | c}\ \bf{Salary} & \bf{Number \: of \: hrs} \\ \sf{143 \: dollar} & \sf{11hrs} \\ \sf{91 \: dollar}& \sf{x}\end{array} \right][/tex]
143 : 91 :: 11 : x
Product of mean = Product of extreme
143 × x = 91 × 11
→ x = [tex]\dfrac{91 × 11}{143}[/tex] = 7hrs
He must work 7 hours to get $91.

I think i already answered this question, but i will rewrite it again! since the angles 'x' and '2x+9' add up to become a supplement angle or a straight line.
We can establish the relation which says that the sum of these two angles is equal to 180.
[tex]x + 2x + 9 = 180[/tex]
[tex]3x + 9 = 180[/tex]
[tex]3x = 180 - 9[/tex]
[tex]3x = 171[/tex]
[tex]x = \frac{171}{3} = 57[/tex]

Answer:
5 months
Step-by-step explanation:
Create an Equation:
m=months
Joe- 40m
Mike- 20m +100
Make each equation equivalent:
40m=20m+100
Solve:
40m-20m=100
20m=100
m=5
If you plug it back in, the equation is satisfied:
40(5)=20(5)+100
200=100+100
200=200

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub. What is the area of the cover? Use Pi = 3. 14 and round the answer to the nearest square foot.
Answer:
38 square feet
Step-by-step explanation:
How do we find the area of a circle?
❖ The area of a circle is πr², where r = radius. For this case, we're going
to approximate pi as 3.14.
How do we find the radius given diameter?
❖ We are given the diameter of Claire's hot tub as 7 feet. The diameter
is 2x the radius, so we divide 7 by 2 to get the radius, which is 3.5
feet.
Solving
[tex]3.14*3.5^2[/tex] [tex]3.14 *12.25[/tex] [tex]38.465[/tex] 38.465 ≈ 38Therefore, the answer is 38 square feet. Have a lovely rest of your day/night, and good luck with your assignments! ♡
