Write a quadratic function f whose zeros are 2 and 9 .
Answers
For this system, x=2 and x=9 are the zeros.
Therefore (x-2) and (x-9) are the binomials which solve to those zeros.
Multiply the binomials together to get the quadratic:
(x-2)(x-9) = x² - 11x + 18
f(x) = x² - 11x + 18
Substituting these values into the general form of a quadratic equation
f(x) = x² - 11x + 18
A quadratic equation is of the form:
f(x) = x² - (Sum of roots)x + (product of roots)
The given roots are 2 and 9
Sum of roots = 2 + 9
Sum of roots = 11
Product of roots = 2 x 9
Product of roots = 18
Substituting these values into the general form of a quadratic equation
f(x) = x² - 11x + 18

a sealed rectangular box measuring 8 x 6 x 18 contains 864 sugar cubes, each measuring 1 x 1 x 1. How many sugar cubes are touching the box ?
Answers
The rectangular box has 6 faces in contact with sugar cubes.
The area of each of two faces is 18*6 = 108 units²
Therefore these two faces touch 2*108 = 216 cubes
There are two other faces each of area 18*8 = 144 units²
Therefore these two faces touch 288 cubes.
There are another two faces, each of area 6*8 = 48 units².
Therefore these faces touch 96 cubes.
The total number of cubes touching the faces of the box are
216 + 288 + 96 = 600
Answer: 600 cubes
The number of cars (c) in a parking lot increases when the parking fee (f) decreases. Write the correct equation for this scenario, and solve for the number of cars when the fee is $6. Fee Cars 20 15 30 10
Answers
Fee Cars
20 15
30 10
Given that you have only two set of data, you can only assume a linear model.
To find the linear model (equation) that predict the number of cars (x) as a functionn of the parking fee (f) you follow, using only two set of data, follow this procedure:
1) Find the slope, m
m = [10 - 15] / [30 - 20] = - 5 / 10 = - 0.5
2) Use the slope-point equation
y - y1 = m (x - x1)
=> y - 10 = - 0.5 (x - 30)
=> y - 10 = - 0.5x + 15
=> y = - 0.5x + 15 + 10
=> y = - 0.5x + 25
or c = - 0.5 f + 25 <-------- equation
Now you can replace 6 for f to get the number of cars when the fee is $6
c = - 0.5 (6) + 25 = - 3 + 25 = 22 <---- this is the number of cars when fee is $6
Answers:
c = - 0.5 f + 25
number of cars = 22

The difference between the mean and median of the data is 50.
What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
Given:
David played a video game 5 times.
The list shows his scores:
4975,5275,4825,5100,4950.
To find the median:
The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data points. To find the median, firstly arrange the data points in ascending order.
4825, 4950, 4975, 5100 and 5275.
So, the middle number is 4975.
The median is 4975.
To find the mean;
The mean = the sum of the scores / 5
The mean = 25125 / 5
The mean = 5025
The difference:
5025 - 4975 = 50
Therefore, the required difference is 50.

6.) 10^13
___ x ___ times larger
Answers
Final answer:
The population of China is approximately 240 times larger than the population of the Marshall Islands. This is calculated by dividing China's population (1.446×[tex]10^9[/tex]) by the Marshall Islands' population (6.025×[tex]10^4[/tex]). (Option 3)
Explanation:
The question asks us to determine how many times larger China's population is compared to the population of the Marshall Islands. To find the answer, we divide the population of China by the population of Marshall Islands:
1.446×[tex]10^9[/tex] (China's population) ÷ 6.025×[tex]10^4[/tex] (Marshall Islands' population).
Carrying out this division, we get a result of approximately 240 times larger. Thus, the population of China is 240 times larger than that of the Marshall Islands.

What's the answer to 1/6d+2/3=1/4(d-2) and can someone explain/work this out with me?
Answers
1/6d + 2/3 = 1/4d - 1/2....multiply everything by the common denominator 12
2d + 8 = 3d - 6 ...subtract 3d from both sides
2d - 3d + 8 = -6 ...subtract 8 from both sides
2d - 3d = -6 - 8.....simplify
-d = - 14...multiply both sides by -1 to make d positive
d = 14

1/6d+2/3=1/4d-1/2
add 1/6d to both sides

Monique Fournier deposited $12,500 into a savings account paying 6.5% annual interest compounded monthly. What amount will she have in her account after 3 years
Answers
A = P(1 + r/n)^nt
A (Amount)
P (Principal)
r (Interest rate)
n (Times per year the interest is compounded)
nt (time in years)
A = 12500(1 + 0.065/12)^3(12)
A = 12500(1.005)^3(12)
A = 12500(1.005)(^36)
A = 12500(1.20)
A = 15,000
Hope I helped :)
Follow below steps;
Monique Fournier wants to find out how much her $12,500 savings account, with an annual interest rate of 6.5% compounded monthly, will grow to after 3 years. To calculate the future value of this investment, we can use the compound interest formula:
FV = P times (1 + r/n)^(nt)
Where:
FV is the future value of the investmentP is the principal amount ($12,500)r is the annual interest rate (6.5% or 0.065 as a decimal)n is the number of times interest is compounded per year (12, since it's compounded monthly)t is the number of years the money is invested (3 years)Plugging the numbers into the formula gives us:
FV = $12,500 times (1 + 0.065/12)^(12 imes 3)
After calculating, Monique's account balance after 3 years will be:
FV = $12,500 times (1 + 0.0054167)^(36)
FV = $12,500 times 1.0054167^36
FV ≈ $12,500 times 1.214669
FV ≈ $15,183.36
After 3 years, Monique Fournier will have approximately $15,183.36 in her savings account

Write an equation of the line containing the point (3,5)and perpendicular to the line 2x- 3y
Answers
Answer:
The equation of the line would be y = -3/2x + 19/2
Step-by-step explanation:
First we need to solve the original equation for y so that we can find the slope.
2x - 3y = 0
-3y = -2x
y = 2/3x
So since the equation has a slope of 2/3, we know the perpendicular slope would be -3/2 (since perpendicular slopes have opposite and reciprocal slopes). Then we can use this and the ordered pair in point-slope form.
y - y1 = m(x - x1)
y - 5 = -3/2(x - 3)
y - 5 = -3/2x + 9/2
y = -3/2x + 19/2

How many more people attended the Magic's games than attended the pacers' games? 582,295 pacers 715,901 magic
Answers
715901-582295=133606
Answer:
133606 persons
Step-by-step explanation:
Number of persons attended the Magic's game= 715,901 games
Number of persons attended the Pacer's game= 582,295 persons
We have to find the number of persons who attend the Magic's game more than Pacer's game.
To find this, we have to find the difference
Number of persons attended the Magic's game= 715,901 games
Number of persons attended the Pacer's game= 582,295 persons
Number of persons who attended More Magic's game= 715901- 582295
Number of persons who attended More Magic's game= 133606 persons
Hence, the correct answer is 133606 persons
