The following is a special trapezoid. Given WX is parallel to ZY. Which of the following is also true about trapezoid WXYZ?
∠W ≅ ∠Z
∠Z and ∠W are supplementary
∠W ≅ ∠X
∠X and ∠Y are complementary
Answers
Answer:
∠Z and ∠W are supplementary
Step-by-step explanation:
In the diagram given showing a special trapezoid, WX and ZY are two opposite sides that are parallel to each other.
Thus, consecutive angles would be supplementary.
Therefore, the only correct option that is true is:
∠Z and ∠W are supplementary.
The test options are incorrect as consecutive angles are not complementary and they are not in themselves congruent to each other.
They ARE supplementary so it WOULD be B <z and <w are supplementary
Look at this set of ordered pairs: (14, 19) (14, 5) (4, 18) Is this relation a function? yes no
Answers
Answer:
This is a relationship, and NOT a function
Step-by-step explanation:
Notice that from the pairs listed, we find that the number 14 in the Domain is connected via the relationship with TWO different numerical values in the Range (with 19 and with 5).Therefore, this cannot be a function, since in such case, each element of the Domain must connect with no more than one element of the Range.

A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizontal force of 0.5 N to the puck. Find the speed and the traveled distance 5 s later.
Answers
Answer:
1) The speed after 5 seconds is 13.[tex]\bar 8[/tex] m/s
2) The distance traveled after 5 seconds is 34.7[tex]\bar 2[/tex] meters
Step-by-step explanation:
1) The given parameters are;
The mass of the hockey puck, m = 0.18 kg
The horizontal force applied by the player, m = 0.5 N
The time at which the speed is calculated, t = 5 seconds after the force is applied
Therefore;
From the equation for the applied force, F = m × a. where a represents the acceleration, by substituting the known values get;
0.5 = 0.18 × a
∴ a = 0.5/0.18 = 50/18 = 25/9 = 2.[tex]\bar 7[/tex]
a = 2.[tex]\bar 7[/tex] m/s²
The speed after 5 seconds is given from the kinematic equation, v = u + a·t
Where;
v = The final velocity
u = The initial velocity = 0 m/s
t = The time = 5 seconds
By substitution of the known values, we get;
v = 0 + 2.[tex]\bar 7[/tex] × 5 = 13.[tex]\bar 8[/tex]
The speed after 5 seconds = 13.[tex]\bar 8[/tex] m/s
2) The distance traveled, s, after 5 seconds is given by the equation, s = u·t + 1/2·a·t²
From which we have;
s = 0 × 5 + 1/2 × 2.[tex]\bar 7[/tex] × 5² = 34.7[tex]\bar 2[/tex]
The distance traveled after 5 seconds = 34.7[tex]\bar 2[/tex] meters

A poster is to have a total area of 500 square centimeters. There is a margin around the edges of 4 cm at the top and 8 cm on the bottom and sides where nothing is printed. Express the printed area A in terms of the width w (in centimeters) of the bottom.
Answers
Answer:
A(w) = 692 - 12w - (8000/w)
Step-by-step explanation:
Since it has a total area of 500 cm², it means that;
A = hw
Where;
A is area
h is height
w is width
Thus;
500 = hw
h = 500/w
We are told that There is a margin around the edges of 4 cm at the top and 8 cm on the bottom and sides where nothing is printed.
Thus;
We have height as; (h - 4 - 8) and width as; (w - 8 - 8)
Thus;
Area = (h - 4 - 8) × (w - 8 - 8)
Area = (h - 12) × (w - 16)
We know that h = 500/w
And we want to find the printed area in terms of the width(w)
Thus;
A(w) = ((500/w) - 12) × (w - 16)
A(w) = 500 - 12w - 8000/w + 192
A(w) = 692 - 12w - (8000/w)
Using the area formula, the appropriate expression for the area of the poster is A(w) = - 8000/w - 12w + 692
Total Area = 500 cm²
Area = Length × width
Entire area can be expressed thus :
500 = l × w l = 500 / wArea with print can be expressed thus :
Length with print = (l - 8 - 4) = (l - 12) cm
Height with print = (w - 2(8)) = (w - 16) cm
Area = (l - 12)(w - 16)
Area = (500/w - 12)(w - 16)
Expressing in terms of width :
A(w) = 500 - 8000/w - 12w + 192
A(w) = - 8000/w - 12w + 692
Hence, the required expression is : A(w) = - 8000/w - 12w + 692
1. The diagram represents a cone.

Calculate the curved surface area of the cone.
2. A sphere has a volume of 500 m3.
(b) Calculate the radius of the sphere. Give your answer correct to 3
significant figures.
Answers
Answer:
1. The curved surface area of the cone is 282.74 cm²
2. Radius of sphere r = 4.924 m
Step-by-step explanation:
1. Height of cone = 12 cm
Diameter of base of cone = 10 cm
Surface Area of cone = ?
The formula used is: [tex]A=\pi r(r+\sqrt{h^2+r^2})\\[/tex]
h= 12 cm
r = diameter/2 r = 10/2 = 5 cm
Putting values and finding surface area
[tex]A=\pi r(r+\sqrt{h^2+r^2})\\A=3.14*5 (5+\sqrt{(12)^2+(5)^2})\\A=15.7 (5+\sqrt{144+25})\\A=15.7 (5+\sqrt{169})\\A=15.7 (5+13)\\A=15.7(18)\\A=282.74 \ cm^2[/tex]
So, the curved surface area of the cone is 282.74 cm²
2. Sphere of Volume = 500 m³
We need to find radius of sphere
The formula used is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]
Putting values and finding radius of sphere
[tex]Volume=\frac{4}{3}\pi r^3\\500=\frac{4}{3}*3.14* r^3\\500=4.186*r^3\\=> r^3=\frac{500}{4.186}\\r^3=119.446\\Taking \ cube \ root \ on \ both \ sides.\\\sqrt[3]{r^3}=\sqrt[3]{119.446}\\r= 4.924 \ m\\[/tex]
So, Radius of sphere r = 4.924 m

Susie is paying $538.66 every month for her $150,000 mortgage. If this is a 30 year mortgage, how much interest will she pay over the 30 years of payments?
Answers
Answer:
Step-by-step explanation:
So First we know she pays (538.66) every month (12months in a year ) for (30) years
So 538.66*12*30 = 193,917.60
Then, we take his total payment minus the what he originally owed.
193,917.60 - 150,000 = $43,917.60
Susie's monthly mortgage payment on her $150,000 home is $538.66. If the loan has a 30-year term, the total interest she will have to pay throughout that time will be $43,917.60.
What is a mortgage?
A mortgage is, to put it simply, a contract that a person forms after borrowing money from a lender (in this case, a bank) and giving the lender a guarantee (in the form of a real estate property) that the money will be paid back in full.
So first one must know as she pays 538.66 every month as there are 12 months in a year and for 30 years, the payment calculation is:
538.66 × 12 × 30 = 193,917.60
Then, deduct the amount he originally owed from his total payment.
193,917.60 - 150,000 = $43,917.60
Therefore, the total interest she will have to pay throughout that time will be $43,917.60.

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 12.3 years, and standard deviation of 0.7 years. If you randomly purchase 14 items, what is the probability that their mean life will be longer than 12 years?
Answers
Answer:
The probability is [tex]P(\= X > 12 ) = 0.72688[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 12.3 \ years[/tex]
The standard deviation is [tex]\sigma = 0.7 \ years[/tex]
The sample size is n = 14
Generally the standard error of the mean is mathematically represented as
[tex]\sigma _{x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma _{x} = \frac{0.7}{\sqrt{14} }[/tex]
=> [tex]\sigma _{x} = 0.1871[/tex]
Generally the probability that their mean life will be longer than 12 years is mathematically represented as
[tex]P(\= X > 12 ) = P(\frac{\= X - \mu }{\sigma} > \frac{12 - 12.3}{ 0.1871 } )[/tex]
[tex]\frac{\= X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \= X )[/tex]
[tex]P(\= X > 12 ) = P(Z > -0.6034 )[/tex]
From the z table the area under the normal curve to the left corresponding to -0.6034 is
=> [tex]P(Z > -0.6034 ) = 0.72688[/tex]
=> [tex]P(\= X > 12 ) = 0.72688[/tex]

The rectangle shown as a perimeter of 70 cm and the given area. It’s length is 8 more than twice it’s width. Write and solve a system of equations to find the dimensions of the rectangle.
The length of the rectangle is ___cm and the width of the rectangle is ___cm.
Answers
width of the rectangle = b = x
length of the rectangle = l = 8 + 2x
Perimeter of the rectangle = 70cm
Also, perimeter of the rectangle = 2(l + b)
70 = 2[x + (8 + 2x)]
70 = 2(x + 8 + 2x)
70 = 2(3x + 8)
70 = 6x + 16
70 - 16 = 6x
54 = 6x
54/6 = x
9 = x
Therefore, b = x
b = 9cm
l = 8 + 2x

B. They have different values but are the same sign.
C. They have the same value but are different signs.
D. They have the same value and the same sign
Answer:
D. They have the same value and the same sign
Step-by-step explanation:
For 72 divided by 9,it is;
72/9 = 8
Usually when we don't have any sign in front of a number, it is said to be positive.
Thus, the answer can be expressed as; +8
Also, when -72 is divided by (-9), it is;
-72/-9
The negative signs will cancel out to give; 8
Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.
This means both divisions yield same values and same signs
