The coordinates of three of the vertices of parallelogram ABCD are A(2, 0), B(4, 3), C(3, 1). How many possibilities are there for the position of the fourth vertex? What are coordinates of the fourth vertex?
Answers
The fourth coordinate for the given parallelogram are going to be (5, 7).
According to the statement
We have to find that the coordinate of the parallelogram.
So, For this purpose, we know that the
A parallelogram is a quadrilateral with opposite sides parallel
From the given information:
The coordinates of three of the vertices of parallelogram ABCD are A(2, 0), B(4, 3), C(3, 1).
Then
Now,
The slope of AB = Slope of CD
(y - 5)/(x - 11) = (1 - 3)/(8 - 2)
6(y - 5) = -2(x - 11)
⇒ 6y + 2x = 52 are going to be the primary equation.
Now,
The slope of BC = Slope of AD
[(y - 3)/(x - 2)] = [(5 - 1)/(11 - 8)]
[(y - 3)/(x - 2)] = 4/3
3(y - 3) = 4(x - 2)
⇒ 3y - 4x = 1 are the second equation.
Now, By substitution
x = 5 and y = 7
Hence, The fourth coordinate for the given parallelogram are going to be (5, 7).

Answers
The property of real numbers illustrated by the given equation is associative property of multiplication.
Associative property states that the number in an equation can be grouped together in any way without the total value of the result changing. There are two types of associative property.
1. Associative property of addition which is given by:
(a+b)+c=a+(b+c)
2. Associative property of multiplication which is given by:
(ab)c=a(bc)
Associative property of multiplication states that the way factors are grouped in a multiplication equation does not change its product.
As the given equation 2. 3(3. 4. 12. 9)=(2. 3. 3. 4)(12. 9) contain multiplication operation, the property of real numbers illustrated is associative property of multiplication.

A square has an area of 90 square inches. Which two consecutive integers does a side length of the square fall between?
Answers
The two consecutive integers in which the side length of the square fall between is 9 and 10
The formula for the area of a square is given as follows:
A = (s)²
where A = area of square
s = length of side of a square
According to the question we have been given that
the area of square = 90 inch²
Now putting the required values in the formula of area we get
(s)² = 90
Taking square root both sides we get
s = √90
As 90 is not a perfect square but it lies between two perfect squares which are 81 and 100.
As √81 = 9 and √100 = 10
Now, √81 ≤ √90 ≤ √100
⇒ 9 ≤ √90 ≤ 10
Hence two consecutive integers such that the side length of the square fall between is 9 and 10

For each function, find the inverse and the domain and range of the function and its inverse. Determine whether the inverse is a function.The formula for converting from Celsius to Fahrenheit temperatures is F=9/5 C+32 .
b. Use the inverse to find the Celsius temperature that corresponds to 25⁰F .
Answers
The formula for converting from Celsius to Fahrenheit temperatures is F = 9/5 C + 32 then the inverse function is one-to-one.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
The formula for converting from Celsius to Fahrenheit temperatures is
F = 9/5 C + 32.
Let the Fahrenheit temperatures is F = 9/5 C + 32
Subtract 32 from both sides:
F - 32 = 9/5 C + 32 - 32
F − 32 = 9/5 C
Multiply both sides by 5:
5(F − 32) = 9C
Divide both sides by 9:
5/9 (F − 32) = C or C = 5/9 (F − 32)
For 27° F
⇒ C = 5/9 (27 - 32)
⇒ C = 5/9 (-5)
⇒ C = -25/9
⇒ -2.78 C° 2.dp.
Yes, the inverse is a one-to-one function.

Range of the function be {y ∈R, y ≥ −7}
What is an inverse function's domain and range?The domain of a relation's inverse is the same as the range of the original relation.
In other words, the y-values of the relation are the inverse's x-values.
Domain of f(x) = {x ∈ R, x ≥ −7} and Range = {y ∈ R, y ≥ 0}
Domain of [tex]f^{-1}[/tex](x)= {x ∈ R}, Range = {y ∈ R, y ≥ −7}
The domain of the function would be all x, such that x+7 ≥ 0, or x ≥ −7. Hence it is {x∈ R, x ≥ −7}.
Consider the range of the function y = √x + 7.
Since √x+7 ≥ 0, it is obvious that y ≥ 0.
Range would be {y ∈ R, y ≥ 0}
The inverse function would be [tex]f^{-1}(x)[/tex] = x² - 7
The domain of the inverse function is all real x, {x ∈ R}
For the range of the inverse function solve y = x²-7 for x.
It would be x = √y+7.
⇒ y + 7 ≥ 0.
Hence, the range of the function be {y ∈R, y ≥ −7}

Interest Suppose you deposit $ 2000 in a savings account that pays interest at an annual rate of 4 % . If no money is added or withdrawn from the account, answer the following questions.
a. How much will be in the account after 3 years?
Answers
There will be $ 2249.728 in the account after 3 years .
Simple Interest : Each year interest is calculated on the principal amount ( the amount that was deposited initially ) .
Simple Interest = ( P * R * T ) / 100
P ( principal amount ) = 2000
R ( Rate of Interest ) = 4
T ( No . of years for which amount is deposited ) = 3
Substituting values
Simple Interest = ( 2000 * 4 * 1 ) / 100
= 80
Amount in account after 1 yr = 2000 + 80
= $ 2080
In second year amount will be = 2080 + [ ( 2080 * 4 * 1 ) / 100 ]
= 2080 + 83.2
= $ 2163.2
After three yrs . amount in account = 2163.2 + [ ( 2163.2 * 4 * 1 ) / 100 ]
= 2163.2 + 86.528
= $ 2249.728
Hence , there will be $ 2249.728 in the account after 3 yrs .

Answers
The product is smaller than the factors of the product.
What can we predict about the product?Let's say that we have two real positive numbers A and B.
If we define 0 < A < 1
Then when we multiply A and B (a real positive number) we will have that:
A*B < B
So the value of B is decreased.
Now, if both numbers are in that range:
0 < A < 1
0 < B < 1
We will have that:
A*B < B
A*B < A
So the product is smaller than A and smaller than B, which are the factors of the product.
So the product is less than both of the factors.
