If the line has a positive slope, it means that the amount is increasing, and if it has a negative slope, it means that the amount is decreasing.
Based on the given information, the function models the amount of money a new business has made over x months. Therefore, we can assume that the function is a linear function, and its graph is a straight line.
Given that negative values represent debt, we can assume that the slope of the line is positive over the interval where the function takes positive values. Therefore, the interval over which the amount is increasing is from zero to infinity, which means that the business is making money and not in debt.
It's essential to note that if the function has a negative slope over any interval, then the amount is decreasing, and the business is losing money. However, we cannot determine this information from the given function's information.

Use The Fundamental Theorem of Calculus, Part 2 to evaluate / - (13 – 12) dt.
The value of the integral [tex]\int -1^1 (13 - 12) dt[/tex] is 26.
How to evaluate the integral?To evaluate the integral [tex]\int-1^1 (13 - 12) dt[/tex] , we need to find an antiderivative of the integrand, which is simply:
∫ (13 - 12) dt = 13t - 12
Using this antiderivative, we can evaluate the definite integral by applying the theorem:
[tex]\int-1^1 (13 - 12) dt = [13t - 12]_{(-1)^1[/tex]
Evaluating this expression at the limits of integration (-1 and 1), we get:
[13(1) - 12] - [13(-1) - 12]
Simplifying, we get:
= 13 - 12 + 13 + 12

Step-by-step explanation:
The coordinates of point B: (0,6)
Coordinates of point C: (3,8)
A kite has 4 sides, of which we have 2 equal pairs, thus the coordinates of point D must be (6,6)
Answer:
(6,6)
Step-by-step explanation:
The question is asking us to complete the half figure, and make it a kite. We can see that the 2 lines AB and BC are half of the shape. In the attachment, I drew a line of symmetry down the middle of the shape.
I also created a point, Y, down the red line, AC, to represent the perpendicular bisector of the 2 diagonals. We can see that line segment BY is the radius of the entire line BD.
This radius is 3 units, so we now know that the diameter horizontally is 6 units. We can draw this on the other side to create point D.
This means that point D is at (6,6).

Abdul flips a weighted coin 64 times and gets 16 tails. Based on experimental probability, how many of the next 40 flips should Abdul expect to come up tails?
Based on experimental probability, Abdul should expect 10 tails in the next 40 flips.
The experimental probability of getting tails is calculated as the ratio of the number of tails obtained in the experiment to the total number of coin flips.
In this case, the experimental probability of getting tails is 16/64, which simplifies to 1/4 or 0.25.
This means that in the long run, we would expect approximately 25% of coin flips to result in tails.
To determine how many of the next 40 flips Abdul should expect to come up tails based on experimental probability,
we can multiply the experimental probability by the total number of flips.
Abdul should expect 0.25 × 40 = 10 tails in the next 40 flips.
Experimental probability of getting tails = Number of tails obtained / Total number of coin flips
Experimental probability of getting tails = 16/64
Experimental probability of getting tails = 0.25 or 25%
Expected number of tails in the next 40 flips = Experimental probability of getting tails × Total number of flips

You have a second job that pays $8.50/hr and your deductions are fica ((7.65%), federal tax withholding (11.25%),and tax withholding (7.25%). If you want to save $220/month), how many many hours do you need to work at your second job? (Remember to round up to the nearest whole hour.)
To save $220 per month while working a job that pays $8.50 per hour with deductions of 26.15%, you would need to work approximately 43 hours per month, rounded up to the nearest whole hour.
To calculate how many hours you would need to work, you need to first determine your hourly pay after deductions. To do this, subtract the percentage of deductions (26.15%) from 100% (100% - 26.15% = 73.85%). Then, multiply your hourly rate by this percentage to get your effective hourly rate after deductions: $8.50 x 0.7385 = $6.27.
To save $220 per month, you need to earn at least $220 more than your expenses from your second job. Assuming a 4-week month, your expenses would need to be at most $55 per week ($220/4 weeks = $55/week).
To earn $55 per week, you need to work for $55/$6.27 = 8.77 hours per week. Rounded up to the nearest whole hour, you would need to work approximately 9 hours per week.
Multiplying this by 4 weeks gives you a total of 36 hours. However, since you need to earn slightly more than $55 per week to account for taxes and rounding, you would need to work approximately 43 hours per month.

If p and q are real numbers in the function f(x)=x4+5x3+px2+qx+30 and f(1)=0, which equation is true?
p + q + 36 = 0 is the equation that is true. From this equation, we can say that p + q = -36.
If we substitute x = 1 in the given function, we get:
f(1) = [tex](1)^4 + 5(1)^3 + p(1)^2 + q(1) + 30[/tex]
= 1 + 5 + p + q + 30
= p + q + 36
We are given that f(1) = 0. Therefore, we have:
p + q + 36 = 0
This is the equation that is true. From this equation, we can say that p + q = -36.
Now, let's see why this is the case. When we substitute x = 1 in the given function and get f(1) = 0, it means that (1, 0) is a point on the graph of the function. This point lies on the x-axis, which means that the function intersects the x-axis at x = 1. Since the x-axis is the line y = 0, this means that f(x) = 0 when x = 1.
Using this information, we can write an equation in terms of p and q. If we substitute x = 1 in the given function and get f(1) = 0, it means that:
f(x) = [tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q))[/tex]
Therefore, we have:
[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = 0[/tex]
Since (1,0) is a point on the graph of the function, we know that x = 1 is a root of this equation. Therefore, we have:
[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = (x - 1)(x^2 + (7+p)x + (36-p-q))[/tex]
We know that (x - 1) is a factor of this equation, so we can use polynomial long division to divide the expression [tex](x^2 + (7+p)x + (36-p-q))[/tex] by (x - 1). The quotient will give us the other two roots of the equation. However, we do not need to find these roots to answer the question. All we need to know is that p + q = -36.

If Mikal uses all his money to buy one type of flour, he has exactly enough money to buy either 12 pounds of wheat flour, or 6 pounds of rice flour, or 4 pounds of almond flour. If Mikal uses all his money to buy an equal number of pounds of all three types of flour, what is the total number of pounds of flour that he can buy?
The total number of pounds of flour he can buy is 7 pounds of flour
Let's assume that Mikal has $1 to spend on flour. According to the problem, he can buy:
- 12 pounds of wheat flour for $1, which means that the price of wheat flour is 1/12 = $0.0833 per pound.
- 6 pounds of rice flour for $1, which means that the price of rice flour is 1/6 = $0.1667 per pound.
- 4 pounds of almond flour for $1, which means that the price of almond flour is 1/4 = $0.25 per pound.
If Mikal spends $1 on an equal amount of all three types of flour, he will spend $1/3 = $0.3333 on each type of flour. To determine how many pounds of each type of flour he can buy, we need to divide $0.3333 by the respective price per pound of each type of flour:
- Wheat flour: $0.3333 / $0.0833 per pound = 3.9996 pounds (rounded to 4 pounds)
- Rice flour: $0.3333 / $0.1667 per pound = 1.9998 pounds (rounded to 2 pounds)
- Almond flour: $0.3333 / $0.25 per pound = 1.3332 pounds (rounded to 1 pound)
Therefore, Mikal can buy 4 pounds of wheat flour, 2 pounds of rice flour, and 1 pound of almond flour with $1. The total number of pounds of flour he can buy is:
4 + 2 + 1 = 7 pounds of flour.

To find the cost of each folder, we need to first set up a system of equations based on the given information. Let x be the cost of a spiral notebook and y be the cost of a folder. We can create the following equations:
1) 2x + y = $6.70 (Rylan's purchase)
2) 3x + 5y = $12.85 (Olivia's purchase)
First, we can solve equation 1 for y:
y = $6.70 - 2x
Next, substitute this expression for y into equation 2:
3x + 5($6.70 - 2x) = $12.85
Now, solve for x:
3x + $33.50 - 10x = $12.85
Combine like terms:
-7x = -$20.65
Now, divide by -7:
x = $2.95
Now that we know the cost of a spiral notebook, we can plug this value back into the expression we found for y:
y = $6.70 - 2($2.95)
y = $6.70 - $5.90
y = $0.80

Let's denote the cost of one apple as 'a' and the cost of one banana as 'b'. We can set up a system of two equations to represent the given information:
4a + 9b = 12.70 (equation 1)
8a + b = 17.70 (equation 2)
We can use either substitution or elimination method to solve for 'a' or 'b'. Let's use the elimination method by multiplying equation 2 by 9 and subtracting it from equation 1:
4a + 9b = 12.70
-(72a + 9b = 159.30) (multiplying equation 2 by 9)
------------------
-68a = -146.60

9 ten thousandths
Answer: 9 x 10^4
Step-by-step explanation:
9 ten thousands in standard form is written like this: 90,000
To convert this into scientific notation, we simply count how many spaces we want to move the decimal point.
So far, our number looks like this with a decimal point: 90000.0
To make this number equal to 9, we have to move the decimal point 4 spaces to the left.
The 4 then becomes our exponent.
So now we have 9 by itself, and all we do is multiply it by 10 with an exponent of 4, to show you are multiplying 10 four times.
Therefore, 9 ten thousands written in scientific notation is 9 x 10^4

3x + $5.50 = 2y
where y is the cost of snacks.
Similarly, buying two tickets and snacks worth a total of $16.50 can be represented by the equation:
2x + y = $16.50
We can solve this system of equations by substituting the first equation into the second equation for y:
2x + (3x + $5.50) = $16.50
5x + $5.50 = $16.50
5x = $11
x = $2.20

2) The President asks you to find the equilibrium level of output for the economy. Suppose you are given that government spending is $10000, investment is $7500, autonomous spending is $2000, the marginal propensity to consume is. 8, and, finally, the level of net exports is -$1000. Now, suppose exports grow by $1000 (Net exports are now $0. ), What would be the equilibrium level of output? What was the multiplier in this case?
The equilibrium level of output in the economy can be calculated using the following formula:
Y = C + I + G + NX
Where:
Y = Equilibrium level of output
C = Consumption
I = Investment
G = Government spending
NX = Net exports
We can calculate consumption using the marginal propensity to consume (MPC) and autonomous spending (A):
C = MPC(Y - T) + A
Where:
T = Taxes (assumed to be 0 in this case)
Substituting in the given values:
C = 0.8(Y - 0) + 2000
C = 0.8Y + 2000
Substituting in the given values for investment, government spending, and net exports:
Y = 0.8Y + 2000 + 7500 + 10000 - 1000
Y = 0.8Y + 19500
Solving for Y:
0.2Y = 19500
Y = 97500
Therefore, the equilibrium level of output in the economy is $97,500.
If net exports increase by $1000, then the new value of net exports (NX) is 0.
Substituting the new value of NX into the formula:
Y = 0.8Y + 2000 + 7500 + 10000 - 0
Y = 0.8Y + 19500
Solving for Y:
0.2Y = 19500
Y = 97500
Therefore, the equilibrium level of output in the economy is still $97,500.
The multiplier is calculated as:
Multiplier = 1 / (1 - MPC)
Substituting in the value of MPC:
Multiplier = 1 / (1 - 0.8)
Multiplier = 5
Therefore, the multiplier in this case is 5.

Where A represents the top of the cliff, B represents the ship and d represents the distance between the ship and the bottom of the cliff.
Since we know that the angle of depression is 37 degrees, then the angle CAB is also 37 degrees. We also know that AB is 100 feet, which is the height of the cliff. We want to find the distance d between the bottom of the cliff and the ship.
We can use the tangent function to find d:
tan(37°) = AB/BD
tan(37°) = 100/d
d = 100/tan(37°)
Using a calculator, we can find that:
d ≈ 132.7 feet
Therefore, the correct answer is (D) 132.7 feet.

The rectangle has a perimeter of 62 millimeters. What is its area?
Let's assume that the length of the rectangle is x and the width is y.
The perimeter of the rectangle is given by:
P = 2x + 2y
Substituting P = 62, we get:
62 = 2x + 2y
Simplifying the above equation, we get:
x + y = 31
The area of the rectangle is given by:
A = xy
To find the area, we need to solve for one of the variables, either x or y. We can use the equation x + y = 31 to solve for y in terms of x:
y = 31 - x
Substituting this expression for y in the equation for the area, we get:
A = x(31 - x)
Expanding the above expression, we get:
A = 31x - x^2
To find the maximum area, we need to find the value of x that maximizes A. We can do this by completing the square:
A = - (x^2 - 31x)
A = - [(x - 15.5)^2 - 240.25]
A = 240.25 - (x - 15.5)^2
The maximum area occurs when x = 15.5, so the dimensions of the rectangle are:
x = 15.5 mm
y = 31 - x = 15.5 mm
The area of the rectangle is:
A = xy = 15.5 mm × 15.5 mm = 240.25 mm^2
Therefore, the area of the rectangle is 240.25 square millimeters.

Stacy and clinton are setting up the community center for a freshman orientation. they set up 8 rectangular tables with 6 chairs each and 5 round tables with 4 chairs each. the chairs are randomly numbered starting with 1 and the freshman will be randomly assigned a seat number.
what is the probability that the first freshman to arrive will be seated at a round table?
a 1/20
b 12/17
c 5/17
d 5/13
"The probability that the first freshman to arrive will be seated at a round table is (5/13)."
To calculate the probability, we need to determine the total number of seats and the number of seats at round tables.
There are 8 rectangular tables with 6 chairs each, so the total number of seats at rectangular tables is 8 * 6 = 48.
There are 5 round tables with 4 chairs each, so the total number of seats at round tables is 5 * 4 = 20.
The total number of seats in the community center is 48 + 20 = 68.
The probability of the first freshman being seated at a round table is the number of seats at round tables (20) divided by the total number of seats (68), which gives us 20/68 = 5/17.
Therefore, the correct answer is option C: 5/17.
In conclusion, the probability that the first freshman to arrive will be seated at a round table is 5/17. This is obtained by dividing the number of seats at round tables by the total number of seats in the community center.
