Answer:
The roots of the functions are x = -1, 0, 2
Step-by-step explanation:
The roots of the function f(x) are the values of x at f(x) = 0To find the roots of a function from the graph of the function, find the points of intersection between the graph and the x-axis because on the x-axis f(x) = 0From the given graph
∵ The graph of the function intersects the x-axis in three points
→ That means the function has 3 roots
∴ The function represented by the given graph has 3 roots
∵ The graph intersects the x-axis at points (-1, 0), (0, 0), and (2, 0)
∴ The values of x-coordinates of these points are -1, 0, 2
∴ At f(x) = 0, x = -1, 0, 2
∵ The roots of the function are the values of x at f(x) = 0
→ That means the roots of the functions are x = -1, x = 0, and x = 2
∴ The roots of the functions are x = -1, 0, 2

CJ earned a score of 75% on his math quiz. Each question on the quiz was worth 1 point, and CJ got 18 questions correct. How many questions were on the quiz? There were questions on the quiz
Answers
Answer:
24 questions
Step-by-step explanation:
Given
[tex]Score = 75\%[/tex]
[tex]Correct\ Questions = 18[/tex]
Required
Determine the number of question
Represent this with n.
Since each question has 1 point each, then
[tex]Score * Number\ of\ questions = Correct\ Questions[/tex]
Substitute values for Score, Number of Questions and Correct Questions
[tex]75\% * n = 18[/tex]
Make n the subject.
[tex]n = \frac{18}{75\%}[/tex]
Convert percent to decimals
[tex]n = \frac{18}{.75}[/tex]
[tex]n = 24[/tex]
Hence, there are 24 questions in total
Challenge A large university accepts 50% of the students who apply. Of the students the
university accepts, 25% actually enroll. If 20,000 students apply, how many actually enroll?
students would actually enroll.
Answers
Answer:
Step-by-step explanation:
20,000 students 50% are accepted so that is 10,000 students of that 10,000 only 25% enroll which is 2,500.
Answer:
2,500 students
Step-by-step explanation:
50% of 20,000 is the amount of students that were accepted. That makes 10,000 students accepted. 25% of 10,000 is the amount enrolled. 25% is 1/4. So 1/4 of 10,000 is 2,500. So 2,500 students enrolled in that university.

The salary scale for an officer starts at $1,700,000 .A rise of $4000 is given at the end of each share . Find the total amount of money the officer will earn in 14 years
Answers
9514 1404 393
Answer:
$24,164,000
Step-by-step explanation:
The yearly salaries form an arithmetic sequence with a first term of 1700000 and a common difference of 4000.
The sum of n terms of an arithmetic sequence with first term a1 and common difference d is ...
Sn = (2a1 +d(n -1))(n/2)
For the given numbers, the sum of 14 years' salaries will be ...
S14 = (2·1,700,000 +4,000(14 -1))(14/2) = 24,164,000
The officer will earn $24,164,000 in a 14-year period.
Clearly, we can see that salary of the officer is in form of Arithmetic progession, where :
First term, a = $ 1,700,000Common difference = $ 4000Number of terms, n = 14And we have to find total salary i.e. [tex] \tt s_{n} = ?[/tex]
Now, we know that :
[tex] \large \underline{\boxed{\bf{S_n = \dfrac{n}{2} \Bigg(2a + (n-1) d\Bigg)}}}[/tex]
By substituting values :
[tex] \tt : \implies S_n = \dfrac{14}{2} \Bigg(2(1700000) + (14-1) (4000)\Bigg)[/tex]
[tex] \tt : \implies S_n = \cancel{\dfrac{14}{2}} \Bigg(2\times 1700000 + 13 \times 4000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \Bigg(3400000 + 52000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \Bigg(3452000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \times 3452000[/tex]
[tex] \tt : \implies S_n = 24164000[/tex]
[tex] \large \underline{\boxed{\bf{S_n = \$ 24,164,000}}}[/tex]
Hence, the total amount of money the officer will earn in 14 years is $ 24,164,000.

This isn't something specific I need to know for school, I'm just curious. I know the most commonly used variables are x, y, and z. But what if you have more then three variables, what are the next letters you are supposed to use?
Answers
Answer:
Any letter you want
Step-by-step explanation:
The letters used for variables don't matter. What matters is what the variables represent: their numerical value. Variables are just to help identify what needs solving. Other common variables are a, b, and c which are found frequently in trigonometry. To answer your question, there are no "next letters." You can use any letter you'd like as a variable because it holds the same numerical value. Basically, the whole alphabet is at your disposal.

Jonas was visiting Garner State Park. At the entrance, he saw a map of the park. The legend stated that 1.5 inches on the map represent 2.5 feet in the park. On the map, how many inches would represent 6 actual feet is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
On the map,
1.5 inches = 2.5 feet
1 feet = 1.5 / 2.5 inches
1 feet = 0.6 inches
Multiply both sides by 6.
6 feet = 3.6 inches
Thus, the required scale in inches for the 6 actual feet is 3.6 inches.

Answers
Answer:
Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.
Step-by-step explanation:
We have been given the information that gretta is selling x raffle ticket by a function
f(x)=10 x
Range is the values that y takes in a particular function
Here, we will get any value which is multiple of 10 since we have a function 10 times of something whatever value we put for x we will get multiple of 10.
Hence, Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

7 is one of the legs while 14 is the hypotenuse. So we set up the equation like this:
[tex]a^2 + 7^2 = 14^2[/tex]
Square 7 and 14:
[tex]a^2 + 49 = 196[/tex]
Minus 49 from both sides:
[tex](a^2 + 49) - 49 = (196) - 49[/tex]
[tex]a^2 = 147[/tex]
Square root both sides:
[tex]\sqrt{a^2} = \sqrt{147}[/tex]
