The coordinates of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
Answer:
of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
The required JKLM is a trapezoid, but as the two sides are equal so JKLM is an isosceles trapezoid.
What is a quadrilateral?A quadrilateral is a four-sided shape as given in the picture in question.
A quadrilateral is a trapezoid if exactly one pair of its opposite sides are parallel. To prove that JKLM is a trapezoid, we can find the slopes of its sides and check if exactly one pair of opposite sides have the same slope. The slope of a line passing through points (x₁, y₁) and (x₂, y₂) is given by (y₂ - y₁) / (x₂ - x₁).
The slope of JK is (4 - (-2)) / (13 - 1) = 6 / 12 = 1/2
The slope of KL is (8 - 4) / (6 - 13) = 4 / (-7) = -4/7
The slope of LM is (4 - (-2)) / (-2 - 6) = 6 / -8 = -3/4
The slope of MJ is (-2 - 4) / (1 - 13) = -6 / -12 = 1/2
Since JK and LM have different slopes, we can conclude that exactly one pair of opposite sides are parallel; thus, JKLM is a trapezoid.
To prove that JKLM is not an isosceles trapezoid, we need to show that none of its sides have equal length. The distance between two points (x₁, y₁) and (x₂, y₂) can be calculated using,
The distance formula = √((x₂ - x₁)² + (y₂ - y₁)²)
We can calculate the lengths of all four sides of JKLM and see if any of them are equal.
JK = √((13 - 1)² + (4 - (-2))²) = √(144 + 36) = √(180) = 6√(5)
KL = √((6 - 13)² + (8 - 4)²) = √(49 + 16) = √(65) = √65
LM = √((-2 - 6)² + (4 - (-2))²) = √(64 + 36) = √(100) = 10
MJ = √((1 - 13)² + (-2 - 4)²) = √(144 + 36) = √(180) = 6√(5)
Since two of the four sides are equal in length, JKLM is an isosceles trapezoid.

I have 24$ to buy bagels. How does the number of bagels I can buy depend on the price of the bagels? Write a formula for the function. If the number of Bagels is N, and the price of the bagel is P, find out what N =.
Note: N is a natural number.
Answer:
N=24/P
The number of bagels(N) would be equal to 24$ divided by the price of the bagels. If there is a remainder, round down because you cannot buy pieces of bagels.
Step-by-step explanation:
If you have 24$ to buy bagels, the amount of bagels depends on the price amount. The price of the bagels could also be called the independent variable, while the amount of bagels you end up getting would be the dependent variable.

George gets the opportunity to make overtime pay at the end of every month. What is overtime?
a.) A rate of pay for hours worked exceeding 40 hours
b.) A rate of pay for working under 40 hours.
c.) Deductions
Answer: a.) A rate of pay for hours worked exceeding 40 hours
Step-by-step explanation:
Just like in the NBA or any sport there can be a section of overtime when the clock runs out and both sides are tied. In this problem overtime means that george can work more than he has to in order to make more money. The key word "exceeding" is just a synonym for more so that's how they try to trick you
let f(x)=2x+3 and g(x)=x×x-1
find a. f(g(x)) b.g(f(x))
Answer:
See explanations below
Step-by-step explanation:
Given the functions f(x)=2x+3 and g(x)=x^2-1
a. Find f(g(x))
f(g(x)) = f(x^2-1)
f(g(x)) = 2(x^2-1)+3
f(g(x))= 2x^2-2+3
f(g(x)) = 2x^2+1
Hence the composite function f(g(x)) is 2x^2+1
b) g(f(x)) = g(2x+3)
g(f(x) = (2x+3)^2-1
g(f(x)) = 4x^2+12x+9-1
g(f(x)) = 4x^2+12x+8

The variables a and b vary directly, and b=8 when a=2.
What is the direct variation equation that relates a and b?
A.
b=2a.
B.
b-4a
C
b=8a
D
b=16a
Answer: b= 4a
( This is the correct answer, which is supposed to be option b, but a negative sign was put instead of an equal sign, so you can change appropriately)
Step-by-step explanation:
Given that a and b vary directly, can be expressed as
a ∝ b
Introducing the constant of proportionality, k, we have that
a = kb
so when a= 2, b= 8 and the constant becomes
2 = k8
k = 2/8=1/ 4
a= 1/4b
Such that
b=4a

Convert the decimal to a fraction in simplest form:
0.333
O 533/1000
1
O 333 —
10
1
O 3 —
333
O 333/1000
Answer:
Decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]
Step-by-step explanation:
Given the decimal
[tex]0.333[/tex]
Multiply and divide by 10 for every number after the decimal point.
There are three digits to the right of the decimal point, therefore multiply and divide by 1000.
Thus,
[tex]0.333=\frac{0.333\cdot \:\:1000}{1000}[/tex]
[tex]=\frac{333}{1000}[/tex] ∵ 0.333×1000 = 333
Let us check if we can reduce the fraction [tex]\frac{333}{1000}[/tex]
For this, we need to find a common factor of 333 and 1000 in order to cancel it out.
But, first, we need to find the Greatest Common Divisor (GCD) of 333, 1000
Greatest Common Divisor (GCD) :
The GCD of a, b is the largest positive number that divides both a and b without a remainder.
Prime Factorization of 333: 3 · 3 · 37
Prime Factorization of 1000: 2 · 2 · 2 · 5 · 5 · 5
As there is no common factor for 333 and 1000, therefore, the GCD is 1.
Important Tip:
As GCD is 1, therefore the fraction can not be simplified.Therefore, decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]
