The standard form of the quadratic equation is given as follows:
y = x² - 2x - 15.
What is a quadratic equation?A quadratic equation is modeled according to the following rule:
y = ax² + bx + c.
From the given table, when x = -3, y = 0, hence the first equation is given by:
(-3)²a + (-3)b + c = 0
9a - 3b + c = 0.
When x = -1, y = -12, hence the second equation is given by:
-12 = a(-1)² + b(-1) + c
a - b + c = -12.
When x = 1, y = -16, hence the third equation is given by:
-16 = a(1)² + b(1) + c
a + b + c = -16.
Then the system of equations to find the coefficients is given as follows:
9a - 3b + c = 0.a - b + c = -12.a + b + c = -16.Using a calculator, the solution to the system is:
a = 1, b = -2, c = -15.
Hence the equation is given by:
y = x² - 2x - 15.

Mr. Coffey bought a house for $195,000. He made a 20% down payment. The interest rate is 5.25% for 30 years. How much does he need to borrow? What is his monthly payment?
Answers
Explanation:
Mr. Coffey bought a house for $195,000 with a 20% down payment.
A 20% down payment, would be 0.20, so $195,000 times 0.20 equals $39,000. Then $195,000 - $39,000 = $156,000.
He bought the bouse for $156,000.
5.25% is 0.525, because you move the decimals back. Understanding the total cost of the house is $156,000 now, we can do $156,000 times 5.25% (0.0525) which equals $8,190.
He would pay $8,190 every 30 years. (if this was the interest rate.)
Assuming if the cost was 20% down payment with the 5.25% interest rate then it would have been: $39,000 times 5.25% = 2047.5.
He would pay $2,047.50 every 30 years. (if this was the interest rate.)
There was no context between the interest rate, so let's assume the obvious which is $2,047.50 every 30 years.

Answers
Answer: 45/10
Explanation:
We want to add
11/5 + 23/10
The first step is to find the lowest common multiple, LCM of the denominators. The LCM of 5 and 10 is 10. We would divide the LCM by each denominator and multiply each numerator by the results. The common denominator of the final fraction would be the LCM. We have
For the first fraction,
10/5 = 2
2 x 11 = 22
For the second fraction,
10/10 = 1
1 x 23 = 23
Thus, the final fraction would be
(22 + 23)/10
= 45/10

The equation of a straight line is y = mx + b where m is the slope and b is the y-intercept then the two points exist (0, -2) and (6, 0).
What is meant by the equation of a straight line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The equation of a straight line is:
y = mx + b where m is the slope and b is the y-intercept.
Therefore, the equation for this line is:
y = (1/3)x - 2
To graph it we can identify two points on the line and connect them.
If x = 0, then y = -2 this is the y-intercept given in the problem.
If x = 6, then y = 0 this is the x-intercept
Therefore, the two points exist (0, -2) and (6, 0).

b) What is the dosage in milligrams per hour, mg/hr?
c) How many milliliters per hour, ml/hr, should be administered?
Answers
The Dosage in milligrams per min, mg/min : 0.01mg / min
The Dosage in milligrams per hour, mg/hr : 0.6mg/hr
The dosage available in milliliters per hour, ml/hr: 6ml/hr
What is Dosage ?
A dosage is a predetermined amount of a drug, food, or pathogen that is administered as a single unit. The dose increases with the amount administered. In medicine, doses are most frequently calculated for substances.
Given,
Dose(mcg) = 10mcg/min
Dose available = 50mg
Volume of dose available = 500ml
a) The dosage in milligram per minute will be:
= 10mcg / 1000mcg
= 0.01mg / min
b) The dosage in milligrams per hour, mg/hr :
= 10mcg x 60min / 1000mcg
= 0.6mg/hr
c) By dosage formula we can write:
= OxV / A
Where,
O = Dose ordered
V = Volume of dose available
A = Dose available
So that we know,
Dose ordered (mg) = 0.6 mg
Volume of dose available (mL) = 500 mL
Dose available (mg) = 50 mg
= 0.6 x 500 / 50
= 6ml/hr
Hence,
The Dosage in milligrams per min, mg/min : 0.01mg / min
The dosage in milligrams per hour, mg/hr : 0.6mg/hr
The dosage available in milliliters per hour, ml/hr: 6ml/hr

Ghost, Inc., has no debt outstanding and a total market value of $395,600. Earnings before interest and taxes, EBIT, are projected to be $53,000 if economic conditions are normal. If there is strong expansion in the economy, then EBIT will be 13 percent higher. If there is a recession, then EBIT will be 22 percent lower. The company is considering a $195,000 debt issue with an interest rate of 8 percent. The proceeds will be used to repurchase shares of stock. There are currently 8,600 shares outstanding. The company has a tax rate of 21 percent, a market-to-book ratio of 1.0, and the stock price remains constant. Calculate earnings per share (EPS) under each of the three economic scenarios before any debt is issued.

Calculate earnings per share (EPS) under each of the three economic scenarios before any debt is issued. (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
a-2. Calculate the percentage changes in EPS when the economy expands or enters a recession. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)
b-1. Calculate earnings per share (EPS) under each of the three economic scenarios assuming the company goes through with recapitalization. (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
b-2. Given the recapitalization, calculate the percentage changes in EPS when the economy expands or enters a recession. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

EPS for recession is $3.7975, EPS for normal is $4.8686, EPS for expansion is $5.5015, and Percentage change in EPS for expansion is 13% and for recession is -22%, EPS under each of the three scenarios after recapitalization is 4360 and percentage change in EPS after the recapitalization is -31.17% and 18.42% for recession and expansion respectively.
A-1) Calculation of EPS under each scenario:
EBIT for expansion condition,
= EBIT × 113%
= $53,000 × 113%
= $59,890
EBIT for recession conditions,
= EBIT × 78%
= $53,000 × 78%
= $41,340
Tax = EBT × 21%
Net income = EBT - Taxes
EPS = Net income ÷ No. of shares
EPS for recession = $3.7975
EPS for normal = $4.8686
EPS for expansion = $5.5015
A-2) Calculation of Percentage change in EPS,
For Expansion = (Expansion EPS - Normal EPS) ÷ Normal EPS
= (5.05 - 4.86) ÷ 4.86
= 13%
For Recession = (Recession EPS - Recession EPS) ÷ Recession EPS
= (4.86 - 3.79) ÷ 4.86
= -22%
B-1) Calculation of EPS under each of the three scenarios after recapitalization,
Market to Book ratio (l) = Market value ÷ Book value
l = $395,600 ÷ Book Value
Book Value = $395,600
Stock Price = Book Value ÷ No. of outstanding shares
= $395600 ÷ 8,600
= 46
No. of shares repurchased = Debt ÷ Stock Price
= $195,000 ÷ 46
= 4240
No. of shares after repurchasing = No. of outstanding shares - No. of shares repurchased
= 8,600 - 4240
= 4360
B-2) Calculating percentage change in EPS after recapitalization,
For Recession = (Recession EPS - Recession EPS) ÷ Recession EPS
= (4.66 - 6.77) ÷ 6.77
= -31.17%
For Expansion = (Expansion EPS - Normal EPS) ÷ Normal EPS
= (8.02 - 6.77) ÷ 6.77
= 18.42%

Answers
From the information given, the area of the kitchen is 54 square feet and it is 9 times as many square feet as does Tina's pantry. This means that the area of Tina's pantry is
54/9 = 6 square feet
If the pantry is 2 feet wide, we would determine its length by applying the formula for determining the area of a rectangle which is expressed as length * width

SInce b is a positive number (being "b" what is understood as the y-intercept) the line DOESN'T pass through the origing of coordinates. So the first option is discarded.
SInce "a"is a negative number (this is the so called "slope' of the line) the line must be slanted, and dropping from left to right Therefore option b is also discarded because that represents a line going up from left to right.
Option c is also discarded, because a is a negative number (not a zero) and lines parallel to the x axis have slope zero.
