Prove the diagonals of the square with vertices P (0,4), Q (4,4), R (0,0) and S (4,0) are perpendicular bisectors of each other.
Step 1: calculate the slope of the diagonals.
The slope of diagonal PS is ____
The slope of diagonal QR is ____
Step 2: calculate the midpoint of the diagonals
The midpoint of PS is ___
Midpoint of QR is ___
The diagonals are perpendicular because the product of their slope is -1, and their midpoint is same (2,2). Hence, it is proved that the diagonals of the given square are perpendicular bisectors of each other.
Given information:
The square with vertices P (0,4), Q (4,4), R (0,0) and S (4,0).
It is required to prove that the diagonals of the given square are perpendicular bisectors.
First, calculate the slope of the diagonals.
The slope of diagonal PS will be,
[tex]m = \dfrac{0-4}{4-0}\\m = -1[/tex]
So, the slope of diagonal PS is -1.
The slope of diagonal QR will be,
[tex]m' = \dfrac{0-4}{0-4}\\m' = 1[/tex]
So, the slope of diagonal QR is 1.
From the slope of the diagonals, the diagonals are perpendicular because the product of slope is -1.
Now, it is required to find the mid-point of the diagonals.
The midpoint of PS will be,
[tex](x,y)=(\dfrac{0+4}{2},\dfrac{4+0}{2})=(2,2)[/tex]
Midpoint of QR will be,
[tex](x,y)=(\dfrac{4+0}{2},\dfrac{4+0}{2})=(2,2)[/tex]
So, the midpoint of both the diagonals is also same.
Therefore, it can be said that the diagonals are perpendicular because the product of their slope is -1, and their midpoint is same (2,2). Hence, it is proved that the diagonals of the given square are perpendicular bisectors of each other.

Answer:
[tex]\frac{11}{8}[/tex] [tex]\text{gallons}[/tex]
Step-by-step explanation:
Given: In [tex]1\frac{1}{2}[/tex] hour, a lawnmower uses [tex]2\frac{1}{16}[/tex] gallon of fuel.
To Find: How many gallons of fuel did the lawnmower use each hour.
Solution:
Number of hour lawnmower used [tex]=1\frac{1}{2}[/tex] [tex]\text{hour}[/tex]
[tex]\frac{3}{2}[/tex] [tex]\text{hour}[/tex]
Fuel consumed by lawnmower [tex]=2\frac{1}{16}[/tex] [tex]\text{gallon}[/tex]
[tex]\frac{33}{16}[/tex] [tex]\text{gallon}[/tex]
Fuel used by lawnmower each hour [tex]=\frac{\text{Total fuel used}}{\text{Total time taken}}[/tex]
[tex]=\frac{\frac{33}{16}}{\frac{3}{2}}[/tex]
[tex]=\frac{11}{8}[/tex] [tex]\text{gallon}[/tex]
Hence the fuel consumed by lawnmower each hour is [tex]=\frac{11}{8}[/tex] [tex]\text{gallon}[/tex]
How many times does 15000 go in to 3000000?
To determine how many times 15000 goes into 3000000, divide 3000000 by 15000. The answer is 200.
To find out how many times 15000 goes into 3000000, we need to perform a simple division.
We divide 3000000 by 15000:
3000000 ÷ 15000 = 200
Thus, 15000 goes into 3000000- 200 times.

Standard deduction on federal income tax return for head of the household is $8350. hilda, a single mom of two, paid $6780 in state income tax and $1230 in mortgage interest last year. how should she file her taxes?
The answer is Claiming standard deduction
Answer:
Hilda can file her taxes by claiming standard deduction.
Step-by-step explanation:
Standard deduction is that amount of someone's income, for which tax is not to be paid, thus reducing the tax bill amount. The amount of the standard deduction is based on one's filing status, age, disability, dependency etc.
Here in this scenario, Hilda can claim standard deductions.
Bob has 36 candy bars and eats 29. What does he have now?
The number of candies Bob left by subtraction will be 7.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
The group's total number of items decreases or becomes lower when we subtract from it.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
As per the given,
Total number of candies = 36
Number of candies Bob ate = 29
Left out = 36 - 29 = 7
Hence "The number of candies Bob left by subtraction will be 7".

Consider the polynomial 9x2 – 16. What is the value of ac? What is the value of b? What two numbers multiply to get ac and add to get b? The factored form of 9x2 – 16 is
The value of ac for the quadratic expression 9x^2 - 16 is -144. The value of b is 0, as it represents the coefficient of x, which is absent in the expression. Therefore, we do not need two numbers that multiply to ac and add to b; the expression is factored using the difference of squares as (3x + 4)(3x - 4).
Explanation:The polynomial 9x2 − 16 is a quadratic expression that can be factored using the difference of squares method. To answer the questions:
The value of ac is the product of the coefficient of x2 and the constant term, which in this case is 9 × (− 16) = − 144.The value of b in the standard form ax2 + bx + c is the coefficient of x, which is 0 since there is no x term in the original expression.To factor, we need two numbers that multiply to ac (which is − 144) and add up to b (which is 0). However, this step is not applicable as the polynomial is already in the form a2 − b2 and will be factored as a difference of squares.The factored form of the polynomial is (3x + 4)(3x − 4).jeffs dog weighs 76 pounds. what is the doofs weight rounded to the nearest tens pounds?

The greatest integer function is defined so that it produces the greatest integer less than or equal to x
What is a function?A relation is a function if it has only One y-value for each x-value.
The greatest integer function, denoted by [x], produces the greatest integer less than or equal to x.
Let us consider a example to understand better
[3.8] = 3, [-2.4] = -3, [0] = 0, and [-7] = -7.
The function f(x) = [[x]] applies the greatest integer function twice to x
so f(x) produces the greatest integer less than or equal to the greatest integer less than or equal to x.
Hence, the greatest integer function is defined so that it produces the greatest integer less than or equal to x
