The correct answer is 4. Any x-values that result in the denominator being equal to 0.
When finding the domain of the quotient of two functions, we need to consider the domains of both the numerator and the denominator. The domain of a function is the set of all possible input values for which the function is defined. For the quotient of two functions, this means that the domain is the set of all x-values that are in the domains of both the numerator and denominator.
However, there is one additional restriction on the domain of the quotient of two functions. The denominator of the quotient cannot be equal to 0, because division by 0 is undefined. Therefore, any x-values that result in the denominator being equal to 0 are not included in the domain of the quotient.
In summary, the x-values that are not included in the domain of the quotient of two functions are any x-values that result in the denominator being equal to 0.
All of the points in the picture of on the same line (Points are: (5,13) (c,10) (2,4)
A. Find the Slope of the line and explain/show your reasoning.
B. Write an equation for the line.
C. What is the value of c? Explain or show your reasoning
Sorry for weird format wouldve uploaded a picture of it but it wasn't working
The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4
What is a slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Given that, All the given points are on the same line and the points are: (5,13) (c,10) (2,4)
Finding the slope;
We know slope of a line passing through two points = (y₂-y₁)/(x₂-x₁)
so, considering the points (5,13) and (2,4)
= (4-13)/(2-5) = 3
Therefore, the slope of the line is 3
Finding the equation,
We know the general equation of a line is given by, y = mx+b,
Where m is slope and b is y intercept.
Solving for b, put x = 5, m = 3and y = 13, in the equation
13 = 5x3+c
b = 13-15
b = -2
Therefore, the equation is y = 3x-2
Finding the missing coordinate c,
Since, all the points lies in same line, so slope will be equal in all the points,
Therefore, (10-13)/(c-5) = 3
c-5 = -1
c = 4
Hence, The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4

A once thriving company in teaneck had its monthly profits, in thousands of dollars, modeled by the equation? f(t) = t^2 9/ 1t^2 2 where t is in months after june 1st, 2002. estimate the company's profits on june 1st, 2002. estimate the company's profits many years into the future
The company's profits on June 1, 2002 is $4500 and the company's profits many years into the future is $1000 per month.
The equation f(t) = (t^2 + 9) / (t^2+2) provides the monthly profits, in thousands of dollar, where t refers to months after June 1, 2002.
The company’s profit on June 1, 2002 using the equation is when t = 0 months
f(0) = (0^2 + 9) / (0^2+2) = 9/2 = 4.5 or $4500.
The company’s profit on many years into the future using the equation is given by:
Limit(t→∞)((t^2+9)/(t^2+2))= Limit(t→∞)(2t/2t)=1

Ariel is correct, the statement is false and the equation has no solutions.
Is Ariel correct or not?Ariel says that the given linear equation has no solutions, so we need to check that.
The linear equation is:
3y - 12 = 3*(y + 1)
If we expand the right side we will get:
3y - 12 = 3y + 3
Now we can subtract 3y in both sides, then we will get:
3y - 12 - 3y = 3y + 3 - 3y
-12 = 3
That is a false equation, thus there are no values of y such that the equation is true, then we don't have any solutions.

Find the equation of the line, given the following information:
Passes through (-9,3) and is perpendicular to y =1/2x+6.
Answer:
y = -2x - 15
Step-by-step explanation:
We are given 2 pieces of information: (1) a point our line passes through, and (2) a line it is perpendicular to. The only thing we need from (2) is the slope.
We know that perpendicular lines have opposite signs and are inverses (denominator and numerator switched). So our line must have a slope of
m = -2
Using our equation for a line: y = mx+b, our line so far is
(I) y = -2x + b
Let's use the point we have (-9,3) and substitute what we know into equation (I) to find b.
x = -9
y = 3
(I) (3) = -2(-9) + b
3 = 18+b
b= -15
Now we have m and b so we can write the equation of our line:
y = -2x - 15

how to do question no 9 b?
Answer:
4 records sold on Wednesday, 32 records sold on Thursday!
Step-by-step explanation:
To do 9b, you need to set up our own equation!
Let's use W to represent records sold on Wednesday and T to represent records sold on Thursday.
It said 36 total records were sold on Wednesday and Thursday. This can be represented with the following equation ...
W + T = 36
It also tell us that on Thursday (T), 8 times the number of records sold on Wednesday were sold on Thursday. In equation form, this looks like ...
T = 8 × W
Now, let's use all this info to solve!
Let's first solve the equation W + T = 36
But, we need values! We have one! We know what T equals!
Let's plug in T
T = 8 × W
W + ( 8 × W ) = 36
Solve
W + 8W = 36
9W = 36
W = 4
4 records were sold on Wednesday!
Let's plug in W in our T equation to see how many records were sold on Thursday.
T = 8 × W
T = 8 × 4
T = 32
32 records were sold on Thursday!
Wednesday can be represented with HALF A CIRCLE

The proportion of stocks invested in the optimal risky portfolio can be calculated with the use of following formula:
Portfolio Invested in the Stock = [(Expected Return of the Stock - Risk Free Rate)*(Standard Deviation of Bond)^2 - (Expected Return of the Bond - Risk Free Rate)*Covariance between Bond and Stock]/[(Expected Return of the Stock - Risk Free Rate)*(Standard Deviation of Bond)^2 + (Expected Return of the Bond - Risk Free Rate)*(Standard Deviation of Stock)^2 - (Expected Return of Stock - Risk Free Rate + Expected Return of Bond - Risk Free Rate)]*Covariance between Bond and Stock
Portfolio Invested in Bond = 1 - Portfolio Invested in the Stock
Here, Risk Free Rate = 4 and Covariance = 32*24*.1250 = 96
Using these values and other information provided in the question, we get,
Portfolio Invested in the Stock = [(10 - 4)*(24)^2 - (7 - 4)*96]/(10 - 4)*(24)^2 + (7 - 4)*(32)^2 - [(10 - 4 + 7 - 4)]*96 = .5593
Portfolio Invested in Bond = 1-.5593 = .4407
Step 2: Calculate Expected Return and Standard Deviation of the Optimal Risky Portfolio
Expected Return = Portfolio Invested in Stock*Expected Return of Stock Portfolio Invested in Bond*Expected Return of Bond = .5593*10% + .4407*7% = 8.68%
Standard Deviation = [(Portfolio Invested in Stock)^2*(Standard Deviation of Stock)^2 + (Portfolio Invested in Bond)^2*(Standard Deviation of Bond)^2 + 2*(Portfolio Invested in Stock)*(Portfolio Invested in Bond)]^(1/2) = [(.5593)^2*(32)^2 + (.4407)^2*(24)^2 + 2*(.5593)*(.4407)*(96)]^(1/2) = 21.90%
Step 3: Calculate Reward-to-Volatility Ratio
The reward-to-volatility ratio can be calculated with the use of following formula:
Reward-to-Volatility Ratio = (Expected Return of the Portfolio - Risk Free Rate)/Standard Deviation of Portfolio = (8.68 - 4)/21.90 = .4221

By dividing the annual percentage rate (APR) by the number of billing cycles per year, the periodic interest rate = 73.89%
What is periodic interest rate?The periodic interest rate is the interest rate that is applied to your credit card balance on a periodic basis, usually on a monthly or daily basis. It is calculated by dividing the annual percentage rate (APR) by the number of billing cycles in a year.
What is the formula to calculate periodic interest rate?The periodic interest rate would be calculated as follows:
Periodic interest rate = APR / number of billing cycles per year
Periodic interest rate = APR / number of billing cycles per year
Since the billing cycle is 31 days long, there are approximately 12/31 = 0.387096774 billing cycles per year. Therefore, the periodic interest rate would be:

a box has width $m$, where $m$ is a prime number. if the box has height $m 2$, length $m-1$, and a volume of 140, what is $m$?
The width of the box m = 5 units
The width of the box = m units
Where m is a prime number
Height of the box = m+2 units
The length of the box = m -1 units
The volume of the box = 140 cubic units
The volume of the box = Length × width × height
140 = m × (m+2) × (m-1)
140 = (m^2 + 2m )(m-1)
140 = m^3 - m^2 + 2m^2 - 2m
140 = m^3 + m^2 - 2m
m^3 + m^2 - 2m - 140 = 0
We can split the equation by taking the common term outside
(m-5) (m^2 + 6m + 28) = 0
Therefore, one value of m = 5
5 is a prime number
