Answer:
(0, -10), (2, 0), (-2, -50)
Step-by-step explanation:
Plug in numbers for the x and solve for it
I will start with 0
y = 5(0 - 1)^2 - 5
y = 5(-1) - 5
y = -5 - 5
y = -10
2
y = 5(2 - 1)^2 - 5
y = 5(1) - 5
y = 5 - 5
y = 0
-2
y = 5(-2 - 1)^2 - 5
y = 5(-9) -5
y = -45 - 5
y = -50
You just keep plugging in numbers until your graph finds its shape. Of course, you can chart the numbers I have already found.
simplify (2x^2-32)/x^2+10+24
Answer:
Step-by-step explanation:
(2x^2-32)/(x^2 + 10x + 24) is less subject to misinterpretation. Write these factors in a vertical column:
(2x^2-32)

(x^2 + 10x + 24)
2(x^2 - 16) 2(x - 4)(x + 4) 2(x - 4)

If x = 8 units, y = 3 units, and h = 1 unit, then what is the area of the parallelogram shown above?
Answer:
8unit²
Step-by-step explanation:
The Area of a parallelogram :
Length of base * height
Length of base, x = 8 units
Height, h = 1 unit
Area = Length of base * height
Area = 8 units * 1 unit
Area = 8unit²

5 The Raven Club sold tickets to the local fall festival. On day one, they sold 50 child tickets and 75 adult
tickets and the total was $525. On day two, they sold 45 child tickets and 65 adult tickets and the total
was $460. What was the cost of the adult tickets?
Answer:
Y = 6
Step-by-step explanation:
On the first day of ticket sales the school sold 3 adult ticket and 8 student tickets for a total of $72. The school took in $152 on the second day by selling 7 adult tickets and 16 student tickets. How much is a student ticket?
Day 1: 3x + 7y = 72
Day 2: 7x + 16y = 152
This becomes a system of equations.
3x+8y=72
3x+8y+−8y=72+−8y (Add -8y to both sides)
3x=−8y+72
3x/3 = −(8y+72)/3
X = (-8/3) y + 24
Substitute (-8/3) y + 24 for x in7x+16y=152:
7(-8/3 y + 24) + 16y = 152
-8/3 y + 168 = 152 (Simplify both sides of the equation)
-8/3 y + 168 − 168 = 152 + (−168) (Add -168 to both sides)
-8/3 y = -16
(-8/3 y)/(-8/3 y) = -16/ -8/3 y (Divide both sides by (-8)/3)
y = 6

What is the area of the shape ?
Answer:
the area is C. 39
Step-by-step explanation: If you split them into there own shapes and add them at the end.

3 x 5 = 15
3 x 4 = 12
12 + 12 = 24

drawbridge at the entrance to an ancient castle is raised and lowered by a pair of chains. The figure represents the drawbridge when flat. Find the height of the suspension point of the chain, to the nearest tenth of a meter, and the measures of the acute angles the chain makes with the wall and the drawbridge, to the nearest degree.
Answer:
4.0 meters, ∠C = 39°, ∠A = 51°
Step-by-step explanation:
Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the Pythagorean Theorem to solve for the height of the chain:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex](3.3)^{2} +b^{2} =(5.2)^{2}[/tex]
[tex]b^{2} =(5.2)^{2}-(3.3)^{2}[/tex]
[tex]b =\sqrt{(5.2)^{2}-(3.3)^{2}}[/tex]
[tex]b=4.0187...[/tex]
[tex]b=4.0 m[/tex]
Now, we can use the Law of Cosines to figure out one of the acute angles:
[tex]c^{2} =a^{2} +b^{2} -2ab(cos(C))[/tex]
[tex](3.3)^{2} =(4.0)^{2} +(5.2)^{2} -2(4.0)(5.2)(cos(C))[/tex]
[tex]cos(C)=\frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)}[/tex]
[tex]C=cos^{-1}( \frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)})[/tex]
[tex]C=39.3915...[/tex]
∠C = 39°
And since we know that all angles in a triangle add up to 180°:
∠A + ∠B + ∠C = 180
∠A + 90 + 39 = 180
∠A = 180 - 90 - 39
∠A = 51°
However, you should always review any answers on the Internet and make sure they are correct! Check my work to see if I made any mistakes!
If the midpoints of the sides of ∆EFG shown below were connected with line segments, what would be the perimeter of the resulting triangle? Explain how you arrived at your answer. *
Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
The midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Given
If the midpoints of the sides of ∆EFG shown below were connected with line segments.
Then the sides of the triangle get half.
Then the perimeter will be of a new triangle will be
[tex]\rm Perimeter = \dfrac{8}{2} + \dfrac{15}{2} +\dfrac{12}{2}\\\\Perimeter = 17.5[/tex]
Thus, the midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
