Answer:
Average Rate of change = 2
Step-by-step explanation:
Given - A rabbit hops 8 meters in one second. After 7 seconds, the rabbit has hopped 20 meters.
To find - What is the rabbit's average rate of change?
Formula used -
Average rate of change of a function f(x) in an interval [a, b] is [tex]\frac{f(b) - f(a)}{b - a}[/tex]
Proof -
Given that,
In 1 second - Rabbit hoops 8 meters
In 7 seconds - Rabbit hoops 20 meters
So,
Average Rate of change = [tex]\frac{20 - 8}{7 - 1}[/tex]
= [tex]\frac{12}{6}[/tex]
= 2
⇒Average Rate of change = 2
what is the perimeter of the trapezoid
Answer:
P = a + b + c + d
Step-by-step explanation:
Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P = a + b + c + d.

It's physics, right?
A. will have box 2.
B. will have box 1
C. will have box 3
Answer:
Part A will be the 2nd line
Part B will be the 1st line
Part C will be the 5th line
*note* I don't know if these lines move as you move them so I getting these answers as if they do not move.
Step-by-step explanation:
Let's start with part A.
It says he rides quickly. This means that as the distance increases, the time will increase slower.
So we are looking for a steep line. The steepest lines are line 2, 3 and 4
We know it can not be the 4th line because these line shows that time is no longer moving, just the distance.
Since it is impossible to freeze time, line 4 does not make any sense. So let's look at line 2 and 3
This can be confusing because it says down hill. So you may think it is line 3. When Cole goes down the hill, he is getting further from home. This means the line has to go up.
So that means part A has to be line 2.
Now let's start with part B
When graphing distance and time, if someone stops, their line stops moving in one direction too.
If you stop moving, you are not gaining any distance but time still moves.
This means we are looking for a line that moves in only 1 direction. These lines are lines 1 and 4.
On line 1, only time is moving
On line 4, only distance is moving
So like I said before, it is impossible to move while time is not moving. So line 4 makes no sense again. Leaving us with line 1.
So part B is line 1
Now we will do part C
It says that Cole rides slowly.
This means the line will not be steep. He is also still moving so it can not be line 1.
So we have line 5 and 6.
Since he is still moving away from the house, the line has to go up in distance and time. So this eliminates line 6
This leaves us with line 5
So the answer to part C is line 5
Hope this helps and have a great day!

The force newton(N),between two particles is inversely propotional to the square of the distance ,d m,between them.When particles are 2metere apart,the force between them is 10 newton.Find the force between the particles when the are 5 metere apart
Answer: [tex]1.6\ N[/tex]
Step-by-step explanation:
Given
The force between the two particles is inversely proportional to the distance between them
[tex]\Rightarrow F\propto \dfrac{1}{d^2}[/tex]
When the distance is 2 m, the force is 10 N. For 5 m distance, it is
[tex]\Rightarrow \dfrac{10}{F_o}=\dfrac{5^2}{2^2}\\\\\Rightarrow F_o=10\times \dfrac{2^2}{5^2}\\\\\Rightarrow F_o=1.6\ N[/tex]
Thus, the force between them is [tex]1.6\ N[/tex]

If 8 boxes of cereal cost $27.60, what is the price of one box?
Answer:
$3.45
Step-by-step explanation:
Let "x" repreesnt the cost of one box. If 8 = 27.60, 1 = "x". Set up a fraction, then solve;
[tex]\frac{8}{27.6}=\frac{1}{x}[/tex]
Step 1: Divide 27.6 by 8
[tex]27.60 \div 8 = 3.45[/tex]
Step 2: Multiply the result by 1

Step-by-step explanation:
The area of a rectangle is represented by the expression 2x2 + 10x + 12. Daniel is convinced that the dimensions of this rectangle could be (2x + 4) and (x + 3) or (x + 2) and (2x + 6). Do you agree or disagree with Daniel? Use words to justify your opinion.
Answer:
I agree with daniel
Step-by-step explanation:
Given the area of a rectangle expressed as;
A(x) = 2x²+10x+12
On factorizing;
A(x) = 2x²+6x+4x+12
A(x) = 2x(x+3)+4(x+3)
A(x) = (x+3)(2x+4)
since A(x) = l(x)w(x)
Hence the legnth and width of the rectangle are 2x+4 and x+3.
Also A(x) = 2x²+6x+4x+12 can be factorized as;
A(x) = 2x²+4x+6x+12
A(x) = 2x(x+2) + 6(x+2)
A(x) = 2x+6(x+2)
Therefore I agree with Daniel. The factor differs due to the difference in arrangement of 4x and 6x in the expression. Precedence of values affects the final factors
the mean of 4 8 9 x and 2x is 6 calculate the value of x
Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3

32.) -3x³ + 6x² - 36x
Step-by-step explanation:
29. 6 ( x² + 2x + 7 )
* distribute the 6 to what's inside of the parenthesis *
6 * x² = 6x²
6 * 2x = 12x
6 * 7 = 42
6x² + 12x + 42
30. 4x ( 1 - x )
* distribute the 4x to what's inside of the parenthesis *
4x * 1 = 4x
4x * -x = -4x²
4x - 4x²
For some reason there is two number 30's
-x² ( x + 5 )
* distribute the -x² to what's inside of the parenthesis *
-x² * x = -x³
-x² * 5 = -5x²
-x³ - 5x²
31.) 3x² ( 4x³ - 5x + 10 )
* distribute the 3x² to what's inside of the parenthesis *
[tex]3x^2*4x^3=12x^5\\3x^2*-5x=-15x^3\\3x^2*10=30x^2\\12x^5-15x^3+30x^2[/tex]
32.) 3x ( -x² +2x - 12 )
* distribute the 3x to what's inside of the parenthesis *
3x * -x² = -3x³
3x * 2x = 6x²
3x * -12 = -36x
-3x³ + 6x² - 36x
Note: When multiplying variables with constants and exponents you add the exponents and multiply the constants
Ex. 3x² * 4x²
Multiply the constants ( 3 and 4 )
3 * 4 = 12
Add the exponents [tex]^2^+^2^=^4[/tex]
[tex]3x^2*4x^2=12x^4[/tex]

As a first step in solving the system shown, Yumiko multiplies both sides of the equation 2x – 3y = 12 by 6. By what factor should she multiply both sides of the other equation so that she can add the equations and eliminate a variable?
5x + 6y = 18
2x – 3y = 12
Answer:
3
Step-by-step explanation:
First, we can start by multiplying the equation 2x - 3y = 12 by six to see where that gets us,
2x - 3y = 12 --> 12x - 18y = 72
12x - 18y = 72
5x + 6y = 18 (other equation)
We can notice that eliminating the y term would be the easiest to go about, so we want to find the number that we can multiply 6 by to get 18. That number is 3, so the factor is 3.
You can use the fact that non of 2 times 6 doesn't include 5 as factor.
There are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.
Those values of the factor are [tex]3[/tex] (for elimination of y) or [tex]-\dfrac{12}{5}[/tex] (for elimination of x)
How to find by what factor should we multiply the equations to eliminate a variable in a system of linear equations of two or more variables?Our aim in doing so is to make the coefficients of same variable equal and with opposite signs so that when we add the equations, that variable gets eliminated because of coefficient becoming zero.
For example, take the given equations and the factor by which Yumiko multiplied the second equation.
5x + 6y = 18
2x – 3y = 12 => 12x - 18y = 72 (since she multiplied this with 6)
Let she multiply the first equation with factor "p"
Then we will have the system as;
[tex]p \times 5x + p \times 6y = p \times 18\\12x - 18y = 72[/tex]
Adding both the equations, we get:
[tex](5p + 12)x + (6p - 18)y = 18p + 72[/tex]
Since there are two variables and since any one of them can be eliminated depending on the value of p, thus we have two cases:
Case 1: Eliminated variable is xThen we have coefficient of x = 0
or
[tex]5p + 12 = 0\\5p = -12\\p = -\dfrac{12}{5}\\[/tex]
Case 2: Eliminated variable is yThen we have coefficient of y = 0
or
[tex]6p - 18 = 0\\6p = 18\\p = \dfrac{18}{6} = 3[/tex]
Thus, there are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.
Those values of the factor are [tex]3[/tex] or [tex]-\dfrac{12}{5}[/tex]

How can you use your results to decide if a triangle with side lengths 16, 18, and 34 is a right triangle?
Answer:
Not a right triangle
Step-by-step explanation:
We can figure out if it is a right triangle or not by using the pythagorean theorem.
a^2 + b^2 = c^2
In this case a and b are 16 and 18
In order for it to be a right triangle, c has to equal 34, in this problem.
16^2 + 18^2 = c^2
= 580^2
= [tex]\sqrt{580}[/tex] = 24.0832
Since 24.0832 does not equal 34, this is not a right triangle

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Money is invested in a saving account at 12% simple interest.
And, After one year there is $1680 in the account.
Now,
Let the original invested amount = x
So, We can formulate;
⇒ x + 12% of x = 1680
⇒ x + 12x/100 = 1680
⇒ 112x = 1680 × 100
⇒ 112x = 1,68,000
⇒ x = 1,68,000/112
⇒ x = $1,500
