Answer: C.) x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit. Is not the answer
Step-by-step explanation: I took the test and got it wrong. I don't know what the answer is.
x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that a local gym sells monthly memberships. The function f(x) = −x² + 18x − 72 models the daily profit in dollars.
The given quadratic equation is solved by equating the function to zero:-
−x² + 18x − 72 = 0
x² - 18x + 72 = 0
x² - 12x -6x + 72 = 0
x ( x -12 ) -6 ( x -12 )= 0
( x - 12 ) ( x - 6 ) =0
x = 12, 6
Therefore, x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
The number of storybooks owned by eight classmates is shown below:
8, 9, 9, 7, 8, 6, 9, 8
Part A:
[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]
Therefore, The mean is 8
Part B: Absolute Deviation= 0
subtract each number by the mean
8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0
(then divide sum by mean) 0 divided by 8 = 8

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3

Find the area of the shaded region
helpp!!
Answer:
1. 116 m
2. 60 cm
Step-by-step explanation:
1. The total area is 12*10 m, or 120 m. The area of the non-shaded region is 7*2 m, or 14. Subtract 14 from 120 to get 116.
BTW the side 12 looks like it is less than the 10, the question is not lengthed properly, just saying
2. A bit trickier, divide the question into 2 parts, a triangle and rectangle.
The rectangle is 12*4 cm, or 48 cm, the triangle is 12 - 3 - 3 = 6 and 8 - 4 = 4
So we use 6 and 4. The area of a triangle is 1/2b * h, half of the base times the height, the base is 6 cm, and the height is 4 cm, 1/2(6) * 4 = 3*4 = 12 cm
48 + 12 = 60 cm

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5660 and his stock in Company B was worth $2500. The stock in Company A has increased 5% since last year and the stock in Company B has increased 9%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
The total percentage increase in the investor's stock account will be 8.6%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The amount he earned from company A and company B is given as,
Earned = $5660 x 0.05 + $2500 x 0.09
Earned = $283 + $225
Earned = $508
Then the total percentage increase in the investor's stock account is given as,
P = [(508) / (5660 + 2500)] x 100
P = (508 / 5910) x 100
P = 0.086 x 100
P = 8.6%
The total percentage increase in the investor's stock account will be 8.6%.

Driving Your brother and sister took turns driving on a 635-mile trip that took 11 hours to complete. Your brother drove at a constant speed of 60 miles per hour and your sister drove at a constant speed of 55 miles per hour. Let x be the number of miles your brother drove and let y be the number of miles your sister drove. Solve the linear system x + y = 11 and 60x + 55y = 635 to find the number of miles each of your siblings drove. Show your work.
Answer: The brother drove 6 hours and the sister drove 5 hours of the trip
Step-by-step explanation:
Your brother drove 35 miles, and your sister drove 600 miles.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have the following system of equations:
x + y = 11 ....(i)
60x + 55y = 635 ....(ii)
Using the elimination method:
Multiply equation 1 by 55, equation 2 by -1, and add both equations together:
55x + 55y = 605, -60x - 55y = -635
Simplify and solve for x: -5x = -30
x = 6
Substitute this value of x back into equation 1 to find y:
y = 11 - 6 = 5
Thus, your brother drove 35 miles, and your sister drove 635 - 35 = 600 miles.

Describe the angle relationship and solve for the x.
Answer:
x = 25
Step-by-step explanation:
The shown angles appear to be on a straight line
Angles on a straight line have a sum of 180°
That being said we can create an equation using this relationship
180 = x + 2 + 153
now we solve for x using basic algebra
step 1 combine like terms
153 + 2 = 155
now we have 180 = x + 155
step 2 subtract 155 from each side
180 - 155 = 25
155 - 155 cancels out
we're left with x = 25
