Answer:
The name of the polygon is rectangle
Step-by-step explanation:
* Lets find the slope of the four sides and the length of two adjacent
side to know what is the name of the figure
∵ The vertices are (1 , 3) , (3 , 4) , (5 , 0) , (3 , -1)
∵ The rule of the slope of a line which passes through the points
(x1 , y1) and (x2 , y2) is m = (y2 - y1)/(x2 - x1)
- Let (x1 , y1) is (1 , 3) and (x2 , y2) is (3 , 4)
∴ m1 = (4 - 3)/(3 - 1) = 1/2
- Let (x1 , y1) is (3 , 4) and (x2 , y2) is (5 , 0)
∴ m2 = (0 - 4)/(5 - 3) = -4/2 = -2
- Let (x1 , y1) is (5 , 0) and (x2 , y2) is (3 , -1)
∴ m3 = (-1 - 0)/(3 - 5) = -1/-2 = 1/2
- Let (x1 , y1) is (3 , -1) and (x2 , y2) is (1 , 3)
∴ m4 = (3 - -1)/(1 - 3) = 4/-2 = -2
- The parallel lines have equal slopes
- The product of the slopes of the perpendicular lines is -1
∵ m1 = m3 and m2 = m4
∴ The sides contains points (1 , 3) , (3 , 4) and (5 , 0) , (3 , -1) are parallel
and the sides contain points (3 , 4) , (5 , 0) and (3 , -1) , (1 , 3) are
parallel
∵ m1 × m2 = 1/2 × -2 = -1
∴ The side contains points (1 , 3) , (3 , 4) is ⊥ to the line contains points
(3 , 4) , (5 , 0)
∵ m3 × m4 = 1/2 × -2 = -1
∴ The side contains points (5 , 0) , (3 , -1) is ⊥ to the line contains points
(3 , -1) , (1 , 3)
- Now lets find the length of the four sides by using the rule
of the distance
- If a segment has two endpoints (x1 , y1) and (x2 , y2), then the length
of the distance is √[(x2 - x1)² + (y2 - y1)²]
∵ The length of the side which contains points (1 , 3) and (3 , 4) is
√[(3 - 1)² + (4 - 3)²] = √[4 + 1] = √5
∵ The length of the side which contains points (3 , 4) and (5 , 0) is
√[(5 - 3)² + (0 - 4)²] = √[4 + 16] = √20 = 2√5
∵ The length of the side which contains points (5 , 0) and (3 , -1) is
√[(3 - 5)² + (-1 - 0)²] = √[4 + 1] = √5
∵ The length of the side which contains points (3 , -1) and (1 , 3) is
√[(1 - 3)² + (3 - -1)²] = √[4 + 16] = √20 = 2√5
∴ The four sides are not equal but each two opposite sides are equal
- From all above
# Each two opposite sides are parallel and equal
# Each two adjacent sides are perpendicular
∴ The name of the polygon is rectangle

Find the volume of the prism.
Answer: 120 units3
Explanation: When finding the base of a prism, you must always multiply the side with the right angle. So basically, 5 is ignored because it does not have a right angle.
1st step: 3*4=12
2nd step: 12/2=6 (because the tringle which is the base is half a square)
3rd step: 6*20=120
The ending is unit 3 because it is volume. Area is unit 2 and we don't know if the prism is in cm so it is not A, or B, and D is the incorrect answer.
In conclusion:
120 units 3

A right come has a slant height of 17 feet, and the diameter of the base is 16 feet. What is the height, h, of the cone?
Answer:
h = 15 feet
Step-by-step explanation:
A right triangle is formed by the slant height, the radius of the base and h, with the slant height being the hypotenuse.
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
Since base diameter = 16 then radius = 8
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take the square root of both sides )
h = [tex]\sqrt{225}[/tex] = 15
The height of the given cone will be 15 feet.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.
Given, A right cone has a slant height of 17 feet, and the diameter of the base is 16 feet.
Since slant height and radius of the base makes a right-angle triangle with the base of radius and hypotenuse of the slant.
Thus, from the Pythagorean theorem:
hypotenuse² = height² + base²
In our case,
Hypotenuse = slant height = 17 feet
Base = radius of base of the cone = 16/2 = 8
Thus,
17² = height² + 8²
height² = 17² - 8²
height² = 225
height = 15 feet
Therefore, the height of the given cone will be 15 feet.

(17 Leon uses 3/4 cup water to make a serving of iced tea.
Part A
If Leon makes 17 servings of iced tea, how many cups of water does
he use?
-cups
Part B
If the water cooler holds 88 servings of iced tea, how many cups of tea
does the cooler have?
cups
Answer:
A.) 12 3/4 cups
B.) 117 1/3
Step-by-step explanation:
Part A
If one serving of ice tea contains 3/4 cup of water, how much does 7 serving have?
To answer this, you must multiply 3/4 and 17
17 is the same as 17/1, so multiply the numerators and denominators
17 x 3 = 51
1 x 4 = 4
51/4 = 12 3/4
So, Leon used 51/4 or 12 3/4 cups of water
Part B
If the cooler has 88 servings of tea, how many cups of water does it have?
To solve this, divide 88 by 3/4
Dividing 88 by 3/4 is the same as multiplying 88 by 4/3.
Again, 88 is the same as 88/1 so multiply the numerators and the denominators.
88 x 4 = 352
1 x 3 = 3
352/3 = 117 1/3
So, there are 352/3 or 117 1/3 cups of water in the cooler
I hope this helps!
To make 17 servings of iced tea, Leon uses 12.75 cups of water. If the water cooler holds 88 servings of iced tea, it contains 66 cups of water.
The student is asking how to calculate the total amount of water needed for 17 servings of iced tea, with each serving using 3/4 cup of water. To find the total, we multiply the number of servings by the amount of water per serving:
17 servings times 3/4 cup/serving = 12.75 cups
For part B, to find out how many cups are in 88 servings:
88 servings times 3/4 cup/serving = 66 cups

Find the volume of the toy rocket shown. The rocket consists of a prism and a pyramid
Answer: [tex]8.66in^3[/tex]
Step-by-step explanation:
The oy rocket shown is formed by a rectangular prism and a regular pyramid whose base is a square.
The volume of the rectangular prism can be calculated with:
[tex]V_{rp}=l*w*h[/tex]
Where "l" is the length, "w" is the width and "h" is the height.
You can observe that:
[tex]l=8in\\w=1in\\h=1in[/tex]
Then, you can substitute values:
[tex]V_{rp}=(8in)(1in)(1in)=8in^3[/tex]
The volume of the regular square pyramid can be calculated with:
[tex]V_p=\frac{s^2*h}{3}[/tex]
Where "s" is the lenght of a side of the base and "h" is the height of the pyramid.
You can observe in the figure that:
[tex]s=1in\\h=2in[/tex]
Substitute into the formula. Then:
[tex]V_p=\frac{(1in)^2(2in)}{3}=\frac{2}{3}in^3[/tex]
The volume of the toy rocket is the sum of the volume of the rectangular prism and the volume of the regular square pyramid. Then:
[tex]V_{toy}=8in^3+\frac{2}{3}in^3=8.66in^3[/tex]
the hypotenuse of a right triangle is 6 more than the shorter leg. the longer leg is three more than the shorter leg. find the length of the shorter leg
Answer:
9
Step-by-step explanation:
shorter leg = x
longer leg = x + 3
Hypotenuse = x + 6
x² + (x + 3)² = (x + 6)²
x² + x² + 6x + 9 = x² + 12x + 36
2x² + 6x + 9 = x² + 12x + 36
x² - 6x - 27 = 0
(x - 9) ( x + 3) = 0
x = 9 or x = -3 (rejected)
The length of the shorter leg of the right angles triangle is 9.
What is a right-angle triangle?
A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle. The right triangle or 90-degree triangle is another name for this triangle.
A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse
The right triangle's three sides are interconnected. The Pythagorean Theorem explains this connection. This theorem states that in a right triangle, [tex]h^{2} = x^{2} + y^{2}[/tex];
where, h = hypotenuse; x = perpendicular side; y = base side;
Given that:
shorter leg = x
longer leg = x + 3
Hypotenuse = x + 6
⇒x² + (x + 3)² = (x + 6)²
⇒x² + x² + 6x + 9 = x² + 12x + 36
⇒2x² + 6x + 9 = x² + 12x + 36
⇒x² - 6x - 27 = 0
⇒(x - 9) ( x + 3) = 0
⇒x = 9 or x = -3.
x=-3 is not possible;
Hence, The length of the shorter leg = 9.

the polynomial ky^3+3y^2-3 and 2y^3-5y+k when divided by (y-5) leave the same remainder in each case. Find the value of k.
Answer:
[tex]k=\frac{153}{124}[/tex]
Step-by-step explanation:
According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).
The first polynomial is :
[tex]p(y)=ky^3+3y^2-3[/tex]
When p(y) is divided by y-5, the remainder is
[tex]p(5)=k(5)^3+3(5)^2-3[/tex]
[tex]p(5)=125k+75-3[/tex]
[tex]p(5)=125k+72[/tex]
When the second polynomial:
[tex]m(y)= 2y^3-5y+k[/tex] is divided by y-5.
The remainder is;
[tex]m(5)= 2(5)^3-5(5)+k[/tex]
[tex]m(5)= 225+k[/tex]
The two remainders are equal;
[tex]\implies 125k+72=225+k[/tex]
[tex]\implies 125k-k=225-72[/tex]
[tex]\implies 124k=153[/tex]
[tex]k=\frac{153}{124}[/tex]
