Answer:
c) Percentages
Step-by-step explanation:
Percentages can be used to compare changes from one period to another.
In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.
For example, let's find percentage increase of the number of students that joined a book club using the parameters below;
Original number of students = 32
New number of students = 36
We will calculate the increase using;
[tex] Increase = original \; number - new \; number [/tex]
Substituting the values, we have;
Increase = 36 - 32 = 4
[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]
[tex] Percentage \; increase = \frac{4}{32} * 100[/tex]
[tex] Percentage \; increase = 0.125 * 100[/tex]
Percentage increase = 12.5%
Therefore, the number of students in the school club increased by 12.5%.

Answer:
110 square inches
Step-by-step explanation:
First, recall the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
Next, identify the base and height dimensions on the figure.
b1 = 13 in; b2 = 9 in; h = 10 in
Next, fill the numbers into the formula and do the arithmetic.
A = (1/2)(13 in + 9 in)(10 in) = (1/2)(22 in)(10 in) = 110 in^2
Last, answer the question asked.
The area of the trapezoid is 110 square inches.

Check for common factors. Since 27 and 72 have
common
factor(s), 2
72
Answer:
2^7 ≠ 7^2
Step-by-step explanation:
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2
The only factor is 2
7^2 = 7 * 7
The only factor is 7
Comparing the factors when written as a repeated multiplication,
2^7 and 7^2 have no common factor :
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
7^2 = 7 * 7 = 49

On average, Haley is able to read 4 5/6 Chapters in the her book each week . How many weeks will it take Haley to read 9 2/3 Chapters
Answer:
2 weeks
Step-by-step explanation:
y = mx + b
y = total number of chapters read = [tex]9\frac{2}{3}[/tex]
m = number of chapters read per week = [tex]4\frac{5}{6}[/tex]
x = number of weeks = what we're solving for
b is not needed to find this solution
[tex]9\frac{2}{3}[/tex] = [tex]4\frac{5}{6}[/tex] x divide [tex]4\frac{5}{6}[/tex] from both sides
x = 2 weeks
Which factor could be multiplied by the given function so that their product causes the graph of f(x) to decrease as x approaches negative infinity?
[tex]f(x)=(2x^2 + 5)(x - 7)[/tex]
Select all that apply.
• -3
• 0.2x
• 5x²
• [tex]-\frac{1}{2}(x + 8)[/tex]
• 4(2x - 7)
Answer:
5x²
-1/2( x+8)
Step-by-step explanation:
The dominant term is 2x^2 *x or 2x^3
We want to know what happens when x goes to negative ∞
2 ( -∞) ^3 → 2 * (-∞) → -∞
As long as we multiply by a positive number, we will still be approaching negative infinity ( or decreasing)
-3 is negative
.2x is negative when x approaches negative infinity
.5 x^2 = .5( -∞)^2 = 5 ( ∞) = ∞ which is positive
-1/2 x is the dominant term = -1/2(- ∞) = ∞ which is positive
4(2x) is the dominant term = 8(- ∞) = - ∞ which is negative
Answer:
3rd and 4th Choices.
[tex]\displaystyle 5x^2\text{ and } -\frac{1}{2}(x+8)[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=(2x^2+5)(x-7)[/tex]
And we want to determine the factor(s) that we can multiply to the above function that will cause the graph of f to decrease as x approaches negative infinity.
We can see that the dominant term will be:
[tex]2x^2(x)=2x^3[/tex]
Thus:
[tex]2(-\infty)^3\Rightarrow -\infty[/tex]
It is already decreasing (shifting towards negative infinity) as x approaches negative infinity.
In order to preserve this, then, the factors must be positive as x approaches negative infinity.
The first factor is -3.
-3 is always negative, so it will make f increase.
The second factor is [tex]0.2x[/tex].
[tex]0.2(-\infty)\Rightarrow -\infty[/tex]
This will also make f increase.
The third factor is:
[tex]5(\infty)^2\Rightarrow \infty[/tex]
This is positive, so it will allow f to remain decreasing as x approaches negative infinity.
The fourth factor is:
[tex]\displaystyle -\frac{1}{2}(-\infty+8)\Rightarrow -\frac{1}{2}(-\infty)\Rightarrow \infty[/tex]
This is also positive, so it will also allow f to remain decreasing.
Lastly, the fifth factor is:
[tex]4(2(-\infty)-7)\Rightarrow 4(-\infty)\Rightarrow -\infty[/tex]
This is negative, so it will make f increasing.
Therefore, our answers are the third and fourth choices.

g(x) = 3x^2– 3x
Find f (4) and g(-3)
helpp please i would appreciate it
Answer:
f(4) = -6, g(-3) = 36
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -2x + 2
f(4) = -2(4) + 2
Simplify the parentheses by multiplying.
f(4) = -8 + 2
Add.
f(4) = -6
g(x) = 3x² - 3x
g(-3) = 3(-3)² - 3(-3)
Simplify the exponent first.
g(-3) = 3(9) - 3(-3)
Simplify the parentheses by multiplying.
g(-3) = 27 + 9
Add.
g(-3) = 36
can someone give me the slope and y-intercept for this ?
The slope is equal to the change in y / change in x.
The change in y is always 5 and the change in x is always 1.
So the change in y / change in x is 5/1 or 5.
The y-intercept is the value of y when x = 0.
So the value of y when x = 0 is 2.
3x - 2 y = 10 and 7 x + 2 y = 30

Here is a diagram of a person standing next to a tree.
The diagram shows two centimeter rulers.
The tree and the person are drawn to the same scale.
The person is approximately 1.65 m tall.
Using the scale diagram, estimate the height of the tree in meters
Answer:
9.9 m
Step-by-step explanation:
According to the scale the person is 2 cm tall, and the tree is 12 cm tall.
So we know that the tree is 6 times taller than the person because,
12 cm = 6 x 2 cm
The actual height of the person is 1.65 m.
Since we know that the tree is 6 times taller than the person, we can find the height of the tree to be
6 x 1.65 m = 9.9 m
