Answer:
1 and 2
Step-by-step explanation:
Zeros of the function is where the function intersect with x-axis (or in other way the zeros of function is x value when y = 0 )
y=x^2-3x+2
(we substitute y with zero)
0 = x^2-3x+2
or in other way
x^2-3x+2 = 0
Then we factor out the function by using the grouping method
(When we should give two numbers that there sum is equal -3 and if we multiply them we get 2)
and these two numbers are -2 and -1
x^2-3x+2 = 0
*Substitute the middle term with -x-2x
x^2-x-2x+2 = 0
*factor out x , then factor out -2
x(x-1)-2(x-1) = 0
*factor out x-2
(x-2)(x-1)=0
Either
x-2 = 0
So
x = 2
Or
x-1 = 0
So
x = 1
in conclusion the zeros of this function is 1,2
Shania bought a $1,455 drum set on an installment plan. The Installment agreement included a 15% down payment and 18 monthly payments of $80.78 each
a. How much is the down payment
b. What is the total amount of the monthly payments?
c. What is the total cost of the plan?
d. What is the finance charge?
The down payment will be $218.25, the total amount of the monthly payments is $1454.04.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Shania bought a $1,455 drum set on an installment plan.
The installment agreement included a 15% down payment and 18 monthly payments of $80.78 each
Down Payment = (15/100)x1444
= $218.25
The total amount of the monthly payment = $80.78x18
= $1454.04
Total cost of the plan = $1454.04 + $218.25
= $1672.29
Finance charge = $1672.29 - $1455
= $217.29
Thus, the down payment will be $218.25, the total amount of the monthly payments is $1454.04.

how to find the circumcenter of a triangle with given vertices
Answer:
What is the formula of area of Circumcircle?
Image result
We know that area of circle = π*r2, where r is the radius of given circle. We also know that radius of Circumcircle of an equilateral triangle = (side of the equilateral triangle)/ √3. Therefore, area = π*r2 = π*a2/3.

Answer:To convert a mixed fraction to an improper fraction, follow these steps:
Multiply the whole number part by the fraction's denominator.
Add that to the numerator. or this might also help,
Then write the result on top of the denominator. To convert a mixed number to an improper fraction, follow these steps: Multiply the denominator of the fractional part by the whole number, and add the result to the numerator.

Last year, a website had 40,000 visitors and this year there is 37,000 visitors what is the percent change of the visitors
Answer:
-7.5 %
Step-by-step explanation:
Percent change can be calculated as
(change)/(original number) * 100, with the * 100 representing a change from decimal (which is what we get from dividing) to percent.
Here, change is (final - original) = 37000-40000 = -3000. Divide this by the original number, 40000, to get -3000/40000 = -0.075. Multiply this by 100 to get -7.5 % as our answer

Which of the following lines are perpendicular to the line y= -1/2x +4 ? (you may choose more than one answer)
A. 2x - y = 1
B. y = 2x
C. 2x + y = 1
D. 1/2x - y =2
E. 2x - y = 3
Answer:
ABE
Step-by-step explanation:
Perpendicular means the slope of the line and the answer are reciprocal to each other.
The slope of the line is -1/2, which means the slope of the answer should be 2.
From A we got: y=2x-1
B:y=2x
C:y=-2x+1
D:y=-1/2x-2
E:y=2x-3
So the answer is ABE

Solve for X please and thank you
Answer:
x = 48
Step-by-step explanation:
Given a secant and a tangent from an external point to the circle, then
the product of the external part and the entire secant is equal to the square of the measure of the tangent , that is
2(2 + x) = 10² = 100 ( divide both sides by 2 )
2 + x = 50 ( subtract 2 from both sides )
x = 48

Answer:
x = 14
Step-by-step explanation:
1. We know that all angle measures in a triangle sum to 180 degrees.
This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.2. (Solving)
Step 1: Combine like terms.
[tex](7x+5x+2x)+(-11-2-3)=180[/tex] [tex]14x -16 = 180[/tex]Step 2: Add 16 to both sides.
[tex]14x - 16 + 16 = 180 + 16[/tex] [tex]14x = 196[/tex]Step 3: Divide both sides by 14.
[tex]\frac{14x}{14}=\frac{196}{14}[/tex] [tex]x = 14[/tex]Step 2: Check if solution is correct.
[tex]7(14)-11+5(14)-2+2(14)-3=180[/tex] [tex]98-11+70-2+28-3=180[/tex] [tex]180=180[/tex]Therefore, the answer is x = 14.

A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $24. Option B is a commission rate of 10% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?
Answer: the answer is $9,600
Step-by-step explanation:
option A = 40(24) = option B = x (.1) where x is her gross sales
40(24) = x(.1)
40(24)/.1 = x = sales = $9600

The probability that a randomly selected Riverside High School student is in twelfth grade is 0.4 and it can be determined by using probability.
Given that,The two-way table shows the estimated number of students who will enroll in three area high schools next year.
A 5-column table has 4 rows.
The first column has entries Mount Woodson High School, Valley High School, Riverside High School, Total number of students.
The second column is labeled Tenth grade with entries 110, 180, 160, 450.
The third column is labeled Eleventh grade with entries 120, 150, 140, 410.
The fourth column is labeled Twelfth grade with entries 80, 120, 200, 400.
The fifth column is labeled Total with entries 310, 450, 500, 1,260.
We have to determine,What is the probability that a randomly selected Riverside High School student is in twelfth grade?
According to the question,The first column has entries Mount Woodson High School, Valley High School, Riverside High School, Total number of students.
The number of randomly selected Riverside High School students is in twelfth grade = 200,
And Total number of students in Riverside High School is = 500
Therefore,
The probability that a randomly selected Riverside High School student is in twelfth grade is,
[tex]\rm P(12th \ grade \students ) = \dfrac{Number \ of \ students \ in \ 12th \ grade }{Total\ number \ of \ students}\\\\ P(12th \ grade \students ) = \dfrac{200}{500}\\\\ P(12th \ grade \students )= 0.4[/tex]
Hence, The required probability that a randomly selected Riverside High School student is in twelfth grade is 0.4.

Q). The sum of four consecutive natural numbers is 166. What are the numbers?
Answer:
see that attachment
I hope it's help you
Let the four consecutive natural numbers are X,X+1,X+2,X+3
Their sum = X+X+1+X+2+X+3 = 4X+6
According to the given problem
Their sum = 166
⇛ 4X+6 = 166
⇛4X = 166-6
⇛4X = 160
⇛X = 160/4
∴ X = 40
X+1 = 40+1 = 41
X+2 = 40+2 = 42
X+3 = 40+3 = 43
The four consecutive natural numbers are 40,41,42,43

The sequence of transformation is a reflection across the x-axis, followed by horizontal shift to the right by 2 units, and vertical shift up by 6 units
The vertices of triangle ABC are given as:
[tex]A = (1,9)[/tex]
[tex]B = (3,12)[/tex]
[tex]C =(4,4)[/tex]
The vertices of triangle A"B"C" are given as:
[tex]A" = (3,-3)[/tex]
[tex]B" = (5,-6)[/tex]
[tex]C" =(6,2)[/tex]
Start by reflecting the coordinates of triangle ABC across the x-axis.
The rule of this transformation is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex]A' =(1,-9)[/tex]
[tex]B' =(3,-12)[/tex]
[tex]C' =(4,-4)[/tex]
Next, shift triangle A'B'C' 2 units right and 6 units up
The rule of this transformation is:
[tex](x,y) \to (x+2,y+6)[/tex]
So, we have:
[tex]A" = (3,-3)[/tex]
[tex]B" = (5,-6)[/tex]
[tex]C" =(6,2)[/tex]
Hence, the sequence of transformation is a reflection across the x-axis, followed by horizontal shift to the right by 2 units, and vertical shift up by 6 units
