Answer:
∠AOC
Step-by-step explanation:
The statement "A to O to C" is talking about each of the points that form an angle. Each point is given a letter as its name.
The symbol ∠ means angle.
You need two lines to form an angle, and you need two points to form a line. By reusing one of the points, you need three points to form an angle. The point that is being reused is always the point in the middle, in this case, that point is called 'O'.

Joe made a scale drawing of the community pool in his town. the pool has a perimeter of 77 meters, what is the length and width in meters?
Answer:
The length of the pool is 28 meters and the width of the pool is 10.5 meters.
Step-by-step explanation:
In the scale drawing of Joe, the community pool has (length : width) = 8 : 3
Let the actual length of the pool is 8x meters and the actual width is 3x meters.
Now, given that the actual pool has a perimeter of 77 meters.
So, 2(8x + 3x) = 77
⇒ 22x = 77
⇒ x = 3.5
So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)
Answer:
The length of the pool is 28 meters and the width of the pool is 10.5 meters.

The question asks how to simplify the monomials 6ab-8ab. This simplification process involves combining like terms. Both terms have the same variables (a and b), so they are like terms and can be combined by subtracting their coefficients.
Here are the steps to simplify:
Identify the coefficients of the like terms: 6 and -8.
Subtract the coefficients: 6 - 8 = -2.
Combine the result with the common variables: -2ab.
Therefore, the simplified form of 6ab-8ab is -2ab.
What is the rate of change in the equation y=-2x+7
Answer:
2
Step-by-step explanation:
m is the slope
y=mx+b
y is equation
m is slope (movement)
b is base
In the equation y=-2x+7, the rate of change (slope) is -2, denoting that for every unit increase in x, y decreases by 2. The +7 represents the y-intercept, the value of y when x equals zero. This concept is fundamental in understanding linear equations, where the rate of change is constant.
Explanation:In the equation y=-2x+7, the rate of change is represented by the coefficient of the x variable, which in this case is -2. This signifies that for each unit increase in x, the value of y decreases by 2. In the context of graphing, this slope (or rate of change) would mean for every step to the right (increase in x), you would take two steps down (decrease in y). For example, if x were to increase from 1 to 2, y would decrease from 5 (plugging x=1 into the equation gives y=5) to 3 (plugging x=2 into the equation gives y=3).
The rate of change is a crucial concept in algebra and lies at the heart of most mathematical models. It plays a vital role in calculus, physics, and engineering, amongst other disciplines. The second number in the equation, '+7', signifies the y-intercept, which is the value of y when x equals zero. This equation represents a straight line, as all linear equations do, and the rate of change (or the slope) is constant across this line.

A 22inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than four times the length of the first piece. Find the length of the pieces
Answer:
The length of the pieces is 3 inch, 6 inch and 13 inch.Step-by-step explanation:
Let, the length of the first piece is x inch.
Hence, the length of the second piece is 2x.
It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.
The total length of the steel is 22 inch.
Hence, x + 2x + 4x + 1 = 22
or, 7x = 21
or, x = 3.
The length of the second piece is [tex]2x = 2\times3 =[/tex] 6 inch.
The length of the third piece is [tex]4x + 1 = 12 + 1 =[/tex] 13 inch.
The lengths of the three pieces of steel are 3 inches, 6 inches, and 13 inches respectively.
Explanation:Let's denote the length of the first piece as x. According to the problemm, the second piece is twice as long as the first piece, which could be represented as 2x. The third piece is said to be one inch more than four times the length of the first piece, which could be represented as 4x + 1. Since the total length of the steel is given as 22 inches, we write down this equation: x + 2x + 4x + 1 = 22.
Simplifying this equation, we get: 7x + 1 = 22. We then subtraact 1 from both sides to isolate the term with x on one side: 7x = 21. Finally, we solve for x by dividing both sides by 7: x = 3.
Therefore, the length of the first piece of steel is 3 inches. The length of the second piece is twice that, or 6 inches. The length of the third piece is four times the length of the first piece plus one inch, or 13 inches.

Select TWO equations that have infinitely many solutions.
A.
2(7 – 4x) = 4(5 – 2x) – 6
B.
6(x – 9) = 6x – 54 + x
C.
4(x + 4) = 2(2x + 5) + 6
D.
5(x – 8) + 10 = 5(x + 2)
Answer: A. 2(7 – 4x) = 4(5 – 2x) – 6
C. 4(x + 4) = 2(2x + 5) + 6
Step-by-step explanation:
Infinitely solution means when all numbers are solutions . Checking the equations given one by one
A. 2(7- 4x ) = 4(5 - 2x ) - 6
Expanding , we have
14 - 8x = 20 - 8x - 6
14 - 8x = 20 - 6 - 8x
14 - 8x = 14 - 8x , this is just a typical example of infinitely many solutions because any value of x chosen will satisfy the equation.
B. 6(x - 9 ) = 6x - 54 + x
Expanding , we have
6x - 54 = 6x + x - 54
6x - 54 = 7x - 54
collecting the like terms
6x - 7x = -54 + 54
- x = 0
x = 0
This equation has just one solution at x = 0 , because 0 is the only value of x that will satisfy the equation
C. 4( x + 4 ) = 2 ( 2x + 5 ) + 6
4x + 16 = 4x + 10 + 6
4x + 16 = 4x + 16
This equation also have infinitely many solutions
D. 5 ( x - 8 ) + 10 = 5 ( x + 2 )
5x - 40 + 10 = 5x + 10
5x - 30 = 5x + 10
This equation has no solution.
Therefore , the equations with infinitely many solutions are equations A and C

Find the maximum value or minimum value for the function f(x) = 0.15(x + 1)² - 3.
0.15
3
1
-3
Answer:
The minimum value for [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].
Step-by-step explanation:
Given function is [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]
We need to find the maximum value or the minimum value for the function.
Now, differentiate [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] w.r.t [tex]x[/tex].
[tex]f'(x) =\frac{d}{dx}(0.15(x + 1)^2 - 3)\\f'(x)=\frac{d}{dx}(0.15(x+1)^2-\frac{d}{dx}(3)\\[/tex]
[tex]f'(x)=2\times 0.15(x+1)\frac{d}{dx}(x+1)-0\\f'(x)=0.3(x+1)(1)\\f'(x)=0.3(x+1)[/tex]
Now, we will equate [tex]f'(x)=0[/tex] to find critical point.
[tex]0.3(x+1)=0\\x=-1[/tex]
Plug this critical point in to the function [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] we get,
[tex]f(-1) = 0.15(-1 + 1)^2 - 3\\f(-1)=-3[/tex]
Also, [tex]f''(x)=0.3[/tex] which is positive, We have minimum value.
So, the minimum value for [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].

Answer:
C
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Consider the numerator;
When (x - 3)(x - 4) = 0
x = 3 or x = 4.
When x > 3 and < 4 (x - 3)(x- 4) will be negative and the denominator (x - 5(x + 6)^2 will be negative so the function will be positive.
So 3 < x < 4 is a part of the answer.
When x > 5 the denominator will be positive and so will be the numerator.
So x > 5 also is a solution.
When x < 3 the numerator will be positive and the denominator will be negative so the function will be negative.

Evaluate when x=-12
Can someone help me I don’t understand this :(
Answer:
2102
Step-by-step explanation:
Evaluate -x³+3x²+5x+1 when x = -12
simply substitue x = -12 into the equation
-x³+3x²+5x+1 when x = -12
= - (-12)³ + 3(-12)² + 5(-12)+1
= -(-1728) + 3(144) - 60 + 1
= 1728 + 432 - 60 +1
= 2102
To evaluate the polynomial -x^3 + 3x^2 + 5x + 1 for x = -12, we substitute -12 for x and simplify, resulting in a final value of 2101.
The student is asking to evaluate the polynomial -x^3 + 3x^2 + 5x + 1 when x = -12. To solve this, we substitute -12 for x in the polynomial and simplify:
Substitute x with -12: -(-12)^3 + 3(-12)^2 + 5(-12) + 1Simplify the equation: -( -12 x -12 x -12) + 3( -12 x -12) + 5( -12) + 1Calculate the powers: -(-1728) + 3(144) - 60 + 1Multiply and add: 1728 + 432 - 60 + 1Combine like terms: 1728 + 432 - 60 + 1 = 2101Therefore, when x = -12, the polynomial evaluates to 2101.
