The vertex of the graph of this equation y = x² - x - 2 is equal to -2.25.
What is the vertex form of a quadratic equation?In this exercise, you are required to determine the vertex form of a quadratic function h(x) that is written in standard form. Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.a represents the leading coefficient.For the given quadratic function y = x² - x - 2 in question 9, the axis of symmetry can be calculated as follows:
Axis of symmetry, Xmax = -b/2a
Axis of symmetry, Xmax = -(-1)/2(1)
Axis of symmetry, Xmax = 1/2
Axis of symmetry, Xmax = 1/2.
Next, we would determine the vertex when x = 1/2 as follows;
y = x² - x - 2
y = (1/2)² - 1/2 - 2
y = 1/4 - 1/2 - 2
y = 0.25 - 0.5 - 2
y = -2.25.

The function f(x)= -3|x-4.7|+2 represents to the temperatures of the solo in degrees Fahrenheit, x minute into an experiment on what interval is temperature positive?
Answers
To find on what interval the temperature is positive, we need to find the values of x for which f(x) is greater than zero.
The function f(x) is defined as:
f(x) = -3|x - 4.7| + 2
Since the absolute value of any real number is always non-negative, we can see that f(x) will be positive only if the expression inside the absolute value bars is less than 2/3. So, we can set:
-3|x - 4.7| + 2 > 0
Solving for |x - 4.7|, we get:
|x - 4.7| < 2/3
This means that x must be within 2/3 units of 4.7. So, the interval on which the temperature is positive is:
4.7 - 2/3 < x < 4.7 + 2/3
Simplifying, we get:
4.0333 < x < 5.3667
Therefore, the temperature is positive on the interval (4.0333, 5.3667).
Find area of the shaded region.

The area of the shaded region of the composite figure is 389 square units.
What is area of composite figure?A geometric shape made up of two or more simpler shapes is known as a composite figure. You must divide a composite figure into simpler shapes and then add up each shape's unique regions to determine the composite figure's area.
The methods you can take to determine a composite figure's area are as follows: Slice up the composite figure into more basic forms. You can separate the composite figure into its component parts, for instance, if it is made up of a rectangle and a triangle.
Calculate the area of each shape separately.
The total area of the composite figure can be calculated by adding the areas of all the simpler shapes.
The shaded region can be divided into a rectangle and a triangle.
The area of the rectangle with l = 19 and w = 17 is:
Area = length x width = 17 x 19 = 323 square units
Now, the dimensions of the triangle are:
base = 17 - 6 = 11
height = 31 - 19 = 12
Thus,
Area = (base x height) / 2 = (11 x 12) / 2 = 66 square units
Now, the total area of the shaded portion is:
Area = 323 + 66 = 389 square units.
Hence, the area of the shaded region of the composite figure is 389 square units.

The complete question is:
In the past few years, many small businesses have been faced with difficulty keeping their doors open, and in many cases large corporations with cash on hand have come in to take over the companies and their real estate. In such case, a large restaurant chain purchased a small corner tavern with plans to use the name to build a local franchise. The cost of buying the franchise naming rights was four times the cost of buying the physical property. If the total purchase price was $1,250,000, how much did the restaurant chain pay for each individual element of the sale ( naming rights and physical property)?
Answers
The restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.
What is sale?Sale refers to the transfer of ownership of goods or services from one person to another in exchange for money or other consideration.
The total purchase price of the franchise naming rights and physical property was $1,250,000.
To calculate the amount paid for each individual element of the sale, the total purchase price must be divided by the two elements.
The total purchase price of $1,250,000 divided by two elements equals $625,000.
This means that the restaurant chain paid $625,000 for the franchise naming rights and $625,000 for the physical property.
The amount of money paid for the franchise naming rights (four times the cost of buying the physical property) can be calculated by multiplying the cost of the physical property, which is
$625,000/4 .
When the cost of the physical property is multiplied by four, the result is $2,500,000.
This means that the restaurant chain paid $2,500,000 for the franchise naming rights.
In summary, the restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.

what is area of rectangle ?
The area of a rectangle is the amount of space that is enclosed within its boundaries. It is the product of the length and width of the rectangle. The formula for the area of a rectangle is:
Area = length x width
In the given question,
Since the two models are of the same rectangular patio, they have the same length and width. Let the length of the rectangle be L and the width be W.
The area of a rectangle is given by the formula A = L x W.
For the model on the left, we are given that the area is 4 sq cm.
A = L x W = 4

Answers
The price of a home that can be purchased is $185,350.
What is interest rate?The supply and demand for credit, the rate of inflation, and the state of the economy as a whole all influence interest rates.
To determine the price of a home that can be purchased, we need to use the given monthly payment of $1112.10 and the interest rate of 6.0% for a 30-year fixed mortgage.
From the table, we can see that the monthly payment per $1000 of mortgage for a 30-year fixed mortgage with a 6% interest rate is $6.00.
So, the mortgage amount can be calculated as:
Mortgage amount = Monthly payment / Monthly payment per $1000 of mortgage
Mortgage amount = $1112.10 / $6.00 = $185,350 (rounded to the nearest cent)
Therefore, the price of a home that can be purchased is $185,350.
Therefore, the answer is (c) $185,350.

A bond currently has a price of $1,050. The yield on the bond is 7%. If the yield increases 20 basis points, the price of the bond will go down to $1,040. The duration of this bond is __________ years.
Answers
The duration of the bond is approximately 0.0045 years or 1.64 days.
HOW TO CALCULATE DURATION OF BOND?We can use the formula for bond price sensitivity to changes in yield to find the duration of the bond:
D = - (1/P) * (dP/dy)
where D is the duration, P is the price of the bond, y is the yield, and dP/dy is the derivative of the bond price with respect to yield.
We are given that the bond price is currently $1,050 and the yield is 7%, so we can plug these values into the formula:
P = $1,050
y = 7% or 0.07
Next, we need to find the derivative of the bond price with respect to yield, which is the percentage change in bond price divided by the percentage change in yield.
We know that if the yield increases by 20 basis points (0.20%), the price of the bond will decrease to $1,040. Using this information, we can calculate the percentage change in bond price and yield:
Percentage change in bond price = (new price - old price) / old price = ($1,040 - $1,050) / $1,050 = -0.0095 or -0.95%
Percentage change in yield = 0.20%
Using these values, we can calculate the derivative of the bond price with respect to yield:
dP/dy = (percentage change in bond price) / (percentage change in yield) = -0.0095 / 0.002 = -4.75
We can now enter each value into the duration formula as follows:
D = - (1/P) * (dP/dy) = - (1/$1,050) * (-4.75) = 0.0045 years or 1.64 days
Therefore, the duration of the bond is approximately 0.0045 years or 1.64 days.

velocity is a unit of measurement for the Distance an object travels in a
the predetermined period of time. Here is a word equation that illustrates the connection between space, speed, and time: velocity is calculated by
dividing the total Distance traveled by the journey time.
We want to find t, so we can rearrange the equation to isolate t:
t = (v - u) / a
Substituting the values we have:
t = (42 m/s - 0 m/s) / (-2 m/s^2)
t = -21 s
Wait a minute, why is the time negative? That's because we chose a coordinate system where positive is in the direction of motion, and negative is opposite to it. In other words, the runner is going in the negative direction of the x-axis, so the displacement (100 meters) is negative. Therefore, the time is negative as well. However, we can take the absolute value of time to get the magnitude:
|t| = |-21 s| = 21 s
So it took the runner 21 seconds to win the race (assuming constant acceleration, which may not be realistic for human sprinters).

How to find annual amount?To find the annual amount, you first need to know the frequency of the payment. If the payment is made monthly, you need to multiply the monthly payment by 12 to get the annual amount. If the payment is made weekly, you need to multiply the weekly payment by 52 (the number of weeks in a year) to get the annual amount.
If the payment is irregular or occurs at different intervals, you can add up the total amount received over the course of the year and use that as the annual amount.

To calculate the balance of Account 1 after 4.8 years, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^{(nt)}[/tex]
where:
A = the final amount
P = the principal (initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time period (in years)
Plugging in the values given in the problem, we have:
[tex]A = 8100(1 + 0.047/365)^{(365*4.8)}[/tex]

To find the value canceled in the second installment, we need to determine the total amount owed at the beginning of the ninth month, and then subtract the first installment paid in the third month.
Let's start by finding the total amount owed at the beginning of the ninth month, using the given financing conditions.
The initial fee of $500,000 is not subject to financing, so we can exclude it from our calculations.
The amount financed is the remaining balance, which is:
$5,000,000 - $500,000 = $4,500,000
The financing rate is 26% capitalizable quarterly, which means that each quarter, the amount owed increases by 26% of the previous balance.
Since there are two quarters between month 3 and month 9, the amount owed at the beginning of month 9 is:
$4,500,000 × (1 + 0.26/4)^2 = $5,279,322.14

What is the equivalent percent?
Answers
Using fractions, we can determine that the enrolment percentage in relation to the Spanish class is 72%.
What are fractions?A fraction is a component of a whole.
Mathematically, the number is expressed as a quotient, where the numerator and denominator are divided.
In a simple fraction, both are integers.
In a complex fraction, a fraction can be found in either the numerator or the denominator.
A suitable fraction has a numerator that is less than its denominator.
So, let's say that x students are enrolled in the Spanish class.
The enrolment in the French class is 0.72 times as large as the attendance in the Spanish class, or 0.72, according to the figures provided.
The enrollment as a percentage of Spanish classes is:
0.72x / x = 0.72
The enrolment percentage in relation to the Spanish class is:
0.72 x 100% = 72%
Therefore, sing fractions, we can determine that the enrolment percentage in relation to the Spanish class is 72%.

What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
Since BD is a median of triangle ABC, it divides side AC into two equal parts. Let's label the midpoint of AC as M. Similarly, YW is a median of triangle XYZ and it divides side XZ into two equal parts, with the midpoint labeled as N.
Since AABC~AXYZ, we know that the corresponding sides are proportional. Thus,
AB/AX = AC/AY = BC/BZ
Since AB = BC (given that B is a vertex of both triangles), we have:
AB/AX = AC/AY
We can rewrite this equation as:
AB/AC = AX/AY ----(1)
Since BD is a median of triangle ABC, we have:
BD = 1/2 AC ----(2)
Similarly, since YW is a median of triangle XYZ, we have:
YW = 1/2 XZ ----(3)
From equation (1), we have:
AB/AC = AX/AY
Multiplying both sides by AC, we get:
AB = AX * (AC/AY)
Now, using equation (2), we can substitute AC/2 for BD:
AB = AX * BD/AY
Finally, using equation (3), we can substitute XZ/2 for YW:
AB = (BD/2) * (XZ/AY)
Therefore, we have found that:
AB = (BD/2) * (XZ/AY)
Hence, we can solve for BD:
BD = 2 * AB * AY / XZ
Note that we need to know the actual values of AB, AY, and XZ to find BD.

From a point 340 feet away from the base of the Peachtree Center Plaza in Atlanta, Georgia, the angle of elevation to the top of the building is 65°. Find the height of
the building. (Hint: The angle of elevation is from the ground up to the top of the
building!)
Answers
Solution:
Given data:
Distance from a point to the Peachtree Center Plaza in Atlanta, Georgia (base) = 340 feet
The angle of elevation to the top of the building = 65°
To find height of the building (perpendicular- p):
tan thetha = p/b
Tan 65°= h/340
tan 65°=2.144507
Now,
h= tan 65° * 340
= 2.144507 * 340
= 729.132 feet
So, the height of the building is 729.132 feet
