Answer:
y=-5/4x-5/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-(-5))/(-6-2)
m=(5+5)/-8
m=10/-8
simplify
m=-5/4
y-y1=m(x-x1)
y-(-5)=-5/4(x-2)
y+5=-5/4x+10/4
y=-5/4x+5/2-5
y=-5/4x+5/2-10/2
y=-5/4x-5/2
In one weekend, 1,200 people attend a play at the theater downtown. A survey of 100 people who attended found that 45 gave the play at least 4 stars out of 5. Use the indicated method to estimate how many people in all would give the play at least 4 stars.
Answer:
540
Step-by-step explanation:
fraction of those surveyed that gave the play at least four stars = 45 / 100 = 0.45
Estimate of people who would rate the play at least four stars = 0.45 x 1200 = 540

Answer:
uhm 1/4???
Step-by-step explanation:
(Polynomials)Expand: (m/2+2n)^3
Answer: m^3/8+3m^2n/2+6mn^2+8n^3 Hope that helps!
Step-by-step explanation:
1. Use cube of sum : (a+b)^3=a^3+3a^2b+3ab^2+b^3
(m/2+2n) ((m/2)^2+2×m/2×2n+(2n)^2)
2. Use division distributive property: (x/y)^a= x^a/y^a
(m/2+2n)(m^2/2^2+2×m/2×2n+(2n)^2)
3. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+(2n)^2)
4. Use multiplication distributive property (xy)^a= x^a y^a
(m/2+2n)(m^2/4+2×m/2×2n+2^2n^2)
5. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+4n^2)
6. Cancel 2
(m/2+2n)(m^2/4+m×2n+4n^2)
7. Regroup terms
(m/2+2n)(m^2/4+2mn+4n^2)
8. Expand by distributing sum groups
m/2(m^2/4+2mn+4n^2)+2n(m^2/4+2mn+4n^2)
9. Expand by distributing terms
m^3/8+m^2n+2mn^2+2n(m^2/4+2mn+4n^2)
10. Expand by distributing terms
m^3/8+m^2n+2mn^2+nm^2/2+4n^2m+8n^3
11. Collect like terms
m^3/8+(m^2n+m^2n/2)+(2mn^2+4mn^2)+8n^3
12. Simplify.
And your answer would be m^3/8+3m^2n/2+6mn^2+8n^3

Find the area of the following figures:
Answer:
The area of the following figure is 400 [tex]m^2[/tex].
Step-by-step explanation:
On the left side of the figure, you'll see that there is a half-circle with a diameter of 20 meters. On the right side of the figure, there is a gap for a half-circle with a diameter of 20 meters. To make the calculation process easier, you can imagine that you take the half-circle from the left side and fit it onto the gap on the right in order to form a 20 meters by 20 meters square. Now you can just multiply the side lengths together to find the area, which will be 20 * 20 = 400 [tex]m^2[/tex].
Determine the missing side length:
Answer:
35 units
Step-by-step explanation:
Using Pythagoras Thereoem:
a² + b² = c²
21² + 28² = c²
c = √21² + 28² = √441 + 784 = √1,225 = 35 units

The question is incomplete. The complete question is :
Martin drew a triangle. Its sides were 3\text{ cm}3 cm3, start text, space, c, m, end text, 4\text{ cm}4 cm4, start text, space, c, m, end text, and 5\text{ cm}5 cm5, start text, space, c, m, end text. It has one right angle and two acute angles. Complete the sentence to describe the triangle Martin drew. Martin's triangle ......
Solution :
A triangle is defined as a close figure with three sides. It is polygon having three angles. If one of the angle is a right angle, then that triangle is known as a right angled triangle.
By Pythagoras theorem, the line opposite to the right angle is called as hypotenuse and it is the longest side in a right angled triangle.
Let a and b be the other sides and let c be the hypotenuse.
So by Pythagoras theorem, we get that [tex]$c^2=a^2+b^2 $[/tex]
From the question, a = 3 cm
b = 4 cm
c = 5 cm
Therefore,
[tex]$5^2=3^2+4^2$[/tex]
25 = 9 + 16
25 = 25
Thus the triangle is a right angled triangle.

Points S, U, and T are the midpoints of the sides of TrianglePQR. Triangle S U T is inside of triangle P Q R. Points S, U, and T are the midpoints of triangle P Q R. Which statements are correct? Check all that apply.
Answer:
1/2 QP = UT
SU ║ RP
Step-by-step explanation:
If UT is parallel to QP, then it is half the length of QP. ΔTUR ~ ΔPQR with a scale factor of 1/2.
It T is the midpoint of PR, then SU is parallel to RP and half its length. Again, ΔQSU ~ ΔQPR with a scale factor of 1/2.

Lydia was doing her homework. She did math for 3/5 of an hour. She did science for 2/3 of an hour, half an hour for art sketches, and 1/10 of an hour for French. and How much time did she spend on her homework? How much time would she have spent if she took 10 minutes break between each subject? Show your work.
Answer:
82 minutes
102 minutes with breaks
Step-by-step explanation:
So there are 60 minutes in an hour. 3/5 of 60 is 36. 2/3 of 60 is 40. And 1/10 of 60 is 6. So adding all those numbers up 36+40+6=82 minutes.
Now if she spent 10 minute breaks in between her assignments then she did 36+10+40+10+6=102 minutes with breaks in between Math and Art also Art and French
A rectangle is placed on the coordinate grid such that one side is on the x-axis and one side is on the
y-axis. What 3-dimensional shape is formed by this rectangle rotating around the y-axis?
cube
O sphere
O cylinder
O rectangular prism
Answer:
A cylinder
Step-by-step explanation:
Picture a can of lets say beans.
It has two circles on its top and bottom side, as well as a cylinder connecting those two parts.
If you were to disassemble the can, you would be left with two circles and a cylinder.
Now the how dose a rectangle connect to a can? Well, if you were to flatten the cylinder you are left with a rectangle and two circles.
Pertaining to the problem, if you were to take a 2d rectangle on a coordinate plane and spin it around the y-axis you would create, in the 3d perspective, a cylinder.
Additionally if you were looking at it from a 2d perspective a circle.
Answer:
Cylinder
