The standard form of the quadratic equation is given as follows:

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.

"What happens if the slope is equal to zero? Provide an example of two points that would be on a line with a zero slope."
Answers
The line which is parallel to X-axis or which is drawn horizontally in the cartesian plane has its slope equal to zero.
As per the question statement, we are supposed to tell the significance of a zero sloped line. Before solving it, we need to know the formula for calculating the slope i.e., m = tanθ, where θ is the inclination angle of the line wrt X-axis.
Slope zero means m = 0 i.e., tanθ = 0 i.e., θ = 0 degrees
Hence a line having NO inclination or in simple words, is parallel to X-axis is known as a zero sloped line.

The graph of a function f is given. Use the horizontal-line test to determine whether f is one-to-one.Is f one-to-one?
Answers
A function is called being one-to-one if, for every value of x, there is only one value of y and vice-versa.
If the graph of the function is given, a practical rule to determine if the function is one-to-one is to use the horizontal-line test.
This test is as follows: Imagine you have a horizontal line (maybe a ruler) and you can move it up and down the grid.
If your line touches the graph only once at every vertical position, then your function is one-to-one.
Now if we test our function drawn in blue, we can touch it only once as we move our line up and down, thus:

Answers
The lifetime in hours of an electronic tube will be of 2 hours.
A probability density function, also known as the density of a continuous random variable, is a function used in probability theory whose value at any given sample (or point) in the sample space can be interpreted as giving a relative likelihood that the random variable's value would be close to that sample. While the absolute likelihood of a continuous random variable taking on any given value is 0, probability density (PDF) at two different samples can be used to infer, in any given draw of the random variable, how much more likely it would be that the random variable would be close to one sample compared to the other sample.
We have,
f(x) = xe^(-x) x>0
= 0 o.w.
Consider,
[tex]E(X) = \int\limits^a_0 {xf} (x)\, dx \\\\E(X) = \int\limits^a_0 {xxe}^{-x} \, dx \\\\E(X) = \int\limits^a_0 {x}^{2}e^{-x} \, dx \\\\E(X) = \int\limits^a_0 {x}^{b-1}e^{-mx} \, dx = \frac{n}{m^{n} } \\\\= 2! = 2[/tex]

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

The value of (s) that satisfy the given equation → 1/4+s=18/20 is 0.65.
What is equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. There are different types of equation such as - Linear Equations, Radical Equations, Exponential Equations, Rational Equations etc.
Given is the following equation written in variable (s)
1/4 + s = 18/20
We have -
1/4 + s = 18/20
We will solve the given expression using the transpose method -
1/4 + s = 18/20
Shifting (s) to the left hand side and constant numbers to right hand side, and then solving for (s), we get -
s = 18/20 - 1/4
s = 9/10 - 1/4
s = 0.9 - 0.25
s = 0.65
The value of s will be 0.65

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
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
