For the new coordinates of point A, that is A' = (x', y'), we have:
x' = 2 . cos (180º) = 2 . (-1) = -2
y' = 10 . cos (180º) = -10
The same happens to the other points. So, for B we have :
x' = 3 . (-1) = -3
y' = -4 . (-1) = 4
And for C:
x' = -3 . (-1) = 3
y' = 1 . (-1) = -1
Therefore, the new coordinates will be:
A'(-2, -10)
B'(-3, 4)
C'(3, -1)
How many two digit numbers have an odd number of factors?
There will be 6 two-digit numbers having an odd number of factors.
According to the question,
We have the following information:
There are two-digit numbers.
It means that the list of numbers is from 10 to 99.
Now, we have to find the numbers with the odd number of factors.
We know that odd numbers are the numbers which are not divisible by 2. For example, 1, 3, 5, etc. are odd numbers.
Note that 1 is also included as a factor.
Now, the numbers with odd number of factors will be the perfect squares as 1 will be added to them and the numbers will become odd.
So, the perfect two-digit square numbers are 16, 25, 36, 49, 64 and 81.
Now, we can prove that these numbers satisfy the given conditions by taking factor of any one number.
Let's take 25. The factors of 25 are 1, 5, and 5. So, in total there are 3 factors.
Hence, there are 6 two-digit numbers having an odd number of factors.

Which expression shows the result of applying the distributive property to 3 (1/5x - 1/7)
The expression used to show the distributive property is 3/5 x - 3/7 .
The examples that follow show how to apply the distributive law towards the set of real numbers R.
Usually, this kind of multiplication is intended when the word "multiplication" is used in elementary mathematicsFrom an algebraic standpoint, real numbers are a field, ensuring the distributive law's applicability. Real numbers are a field in algebra, guaranteeing the applicability of the distributive law.The distributive principle of binary operations generalizes the distributive law, which asserts that equality holds throughout mathematicsThe law states that p·(q + r) = (p · q) + (q · r).Now the given expression is 3 (1/5x - 1/7)
Therefore it can be broken down into smaller parts by using the distributive property.

All sixth grade students are asked to bring something for the fall dance. One student brought 1 ½ gallon of apple juice and another student brought 3 ½ gallon of apple juice. Each serving is ⅓ cup. Given this amount, how many students would be able to have some apple juice ?
Based on the gallons of apple juice brought by the students, and the serving per gallon, the number of students that would have some apple juice is 15 students
How to find the number of students?First, find the total amount of juice that the students brought of apple juice:
= 1 ½ + 3 ½
= 3/2 + 7/2
= 10 / 2
= 5 gallons
If each serving is in a 1/2 cup, then the number of students that would be able to get some apple juice is:
= Number of gallons of juice / Number of cups per serving
= 5 ÷ ⅓
= 5 x 3/1
= 15 / 1

Which of the following is a possible step used in eliminating the y-term?
The possible step used in eliminating the y-term in Equation P: y + z = 6 Equation Q: 8y + 7z = 1 is (y + z = 6) * (−8)
The two equations are :
Equation P: y + z = 6

What is simultaneous linear equation?Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution.
A system of simultaneous linear equations is any set of two or more linear equations that share the same unknown variables. Finding values for the unknown variables that simultaneously satisfy all of the equations is required to solve such a system.
Two linear equations in two variables together are known as simultaneous linear equations.
The solution of the system of simultaneous linear equations is the ordered pair (x, y) that satisfies both linear equations.
Based on the given conditions,
Equation P: y + z = 6 ( Equation-1 )
Equation Q: 8y + 7z = 1 ( Equation-2 )
To solve the above simultaneous linear equation multiply the equation-1 with (-8)
So,
We can write,
⇒ ( y + z = 6 ) * (-8)
-8y - 8z = -48 ( Equation-3 )
Now add Equation (3) with Equation (2)
Then,
-8y - 8z = -48
8y + 7z = 1
----------------------------
-z = -47
z = 47
Therefore,
The expression ( y + z = 6 ) * (-8) is a possible step used in eliminating the y-term.

The school athletic director has a storage closet that is 4 and 1/2 ft long and 2 and 2/3 ft deep and 6 ft tall she wants to put carpet in the closet how much carpeting will she need
Answer:
3 ft^2
Step-by-step explanation:
We'll assume the carpet is only for the closet floor. In that case we don't need the closet height.
Area of the floor can be calculated by multiplying the length (4 1/2 feet) and depth (2/3 foot):
Area = (4 1/2 feet)*(2/3 feet)
Area = (9/2 ')*(2/3 ')
Area = (18/6)'
Area = 3 ft^2
draw a picture to solve. Mandi has 8 dog biscuits. She has 7 dog bowls. Each dog bowl gets the same number of dog biscuits. How many dog biscuits are in each bowl?
If Mandi has 8 dog biscuits, she has 7 dog bowls and each dog bowl gets the same number of dog biscuits, then the number of dog biscuits in each bowl is 1.14 biscuits
Number of dog biscuits that Mandi has = 8 dog biscuits
Number of dog bowls that Mandi has = 7 dog bowls
Each dog bowl get the same number of dog biscuits.
To find the number of dog biscuits in each bowl we have to do the division
Number of dog biscuits in each bowl = Number of dog biscuits that Mandi has ÷ Number of dog bowls that Mandi has
Substitute the values in the equation
= 8/7
= 1.14 biscuits
Hence, if Mandi has 8 dog biscuits, she has 7 dog bowls and each dog bowl gets the same number of dog biscuits, then the number of dog biscuits in each bowl is 1.14 biscuits

Consider P(x) = x^3+3x^2-4, and c=-2. Show the given value of c is a zero of P(x) (this could be done through synthetic division), find all zeros of P(x), and write P(x) in factored form.
Zeros:
Factored form: P(x)=
Answers:
Zeros: -2 and 1
Factored form: P(x) = (x+2)(x+2)(x-1)
====================================================
Explanation:
One way to show that c = -2 is a zero or root of P(x) is to plug it in as the x value and simplify. If we get P(x) = 0, then that input is a root.
P(x) = x^3+3x^2-4
P(-2) = (-2)^3+3(-2)^2-4
P(-2) = -8+3(4)-4
P(-2) = -8+12-4
P(-2) = 4-4
P(-2) = 0
In short, the input x = -2 leads to the output P(x) = 0.
This confirms -2 is a root of P(x). By extension, this tells us that (x+2) is a factor of P(x).
We can determine the other factor using synthetic division as shown in figure 1. See the image below.
The synthetic division table shows us getting a remainder of 0, as highlighted in yellow.
The other stuff in pink represents the coefficients of the quotient.
We have the coefficients 1, 1, -2 which forms 1x^2+1x-2 and that simplifies to x^2+x-2
This further factors to (x-1)(x+2) because we're looking for two numbers that a) multiply to -2 and b) add to 1. Use the FOIL rule to expand (x-1)(x+2) and you should get x^2+x-2 again. This helps confirm the factorization was done correctly.
---------------------
In short, we found that P(x) = (x+2)(x^2+x-2) and it fully factors to P(x) = (x+2)(x+2)(x-1)
Each factor leads to a root.
x+2 = 0 leads to the root x = -2
x-1 = 0 leads to the root x = 1
Visually, each root is an x intercept where the curve either crosses the x axis or touches it before bouncing away. See figure 2 below.
