Based on these calculations, option 1 gives you the cheaper price per square inch of pizza.
To determine which option will give you a cheaper price per square inch of pizza, you will need to compare the prices of the two options and calculate their respective prices per square inch.
Let's say option 1 is a large pizza with a diameter of 18 inches and costs $20, while option 2 is a medium pizza with a diameter of 14 inches and costs $15.
To calculate the area of each pizza, you need to use the formula for the area of a circle:
A = πr^2
For option 1, the radius is 9 inches (half of the diameter), so the area is:
A = π(9)^2 = 81π square inches
For option 2, the radius is 7 inches (half of the diameter), so the area is:
A = π(7)^2 = 49π square inches
Now you can calculate the price per square inch for each option by dividing the cost by the area:
Option 1:
Price per square inch = $20 / (81π) = $0.078/square inch
Option 2:
Price per square inch = $15 / (49π) = $0.098/square inch
Based on these calculations, option 1 gives you the cheaper price per square inch of pizza.

1. Given XY and ZW intersect at point A Which conjecture is always true about he giver statement? A. XA = AY B. XAZ is acute C. XY is perpendicular to XY D. X, Y, Z and W are noncolinear.
The conjecture "X, Y, Z and W are noncolinear" is always true when given that line segments XY and ZW intersect at point A. So option D is the correct answer.
When line segments XY and ZW intersect at point A, it means that X, Y, Z, and W do not all lie on the same line. Since they do not all lie on the same line, they are considered non-collinear.
The conjecture "XA = AY" is not always true. It is only true if the lines XY and ZW are perpendicular bisectors of each other. The conjecture "XAZ is acute" is not always true. It is only true if angle ZAY is obtuse, in which case angle XAZ would be acute. The conjecture "XY is perpendicular to XY" is not a valid conjecture because it is a statement that XY is perpendicular to itself, which is always true but not informative.So the correct answer is option D. X, Y, Z and W are noncolinear.

A restaurant in Richmond, BC, lists the prices on its menus in fractions of a dollar. Three friends have lunch at the restaurant. Each of 3 friends orders a veggie mushroom cheddar burger for 11 % ( , with a glass of water to drink.
What was the total bill be fore taxes, in fractions of a dollar?
If each of the 3 friends orders a veggie mushroom cheddar burger for 11%, the cost of each burger would be:
11% of $1.00 = $0.11
Since the prices are listed in fractions of a dollar, we can express the cost of each burger as 11/100 of a dollar.
So, the total cost of 3 veggie mushroom cheddar burgers would be:
3 x 11/100 = 33/100 = $0.33
Assuming that the glass of water is free, the total bill before taxes would be $0.33 for the 3 burgers. However, it's important to note that this calculation is based on the assumption that the prices are listed in fractions of a dollar, which may not be the case. If the prices are listed in a different unit, the calculation would need to be adjusted accordingly.

" Full Boat Manufacturing has projected sales of $115 million next year. Costs are expected to be $67 million and net investment is expected to be $12 million. Each of these values is expected to grow at 14 percent the following year, with the growth rate declining by 2 percent per year until the growth rate reaches 6 percent, where it is expected to remain indefinitely.

What is your estimate of the current stock price?
The estimate of the current stock price is $13.11 per share.
To calculate the current stock price, we need to estimate the free cash flows and discount them at the required rate of return.
First, we determine the firm's free cash flow (FCFF) for the following year.
FCFF = Sales - Costs - Net Investment*(1-t)
= $115 million - $67 million - $12 million*(1-0.21)
= $31.02 million
Now, we will calculate the expected growth rate in FCFF
g = (FCFF Year 2 / FCFF Year 1) - 1
FCFF Year 2 = FCFF Year 1 × (1 + g)
g = (FCFF Year 2 / FCFF Year 1) - 1
= (FCFF Year 1 × (1 + 0.14) × (1 - 0.02) / FCFF Year 1) - 1
= 0.12
We can now use the Gordon growth model to estimate the current stock price
Current stock price = FCFF Year 1 × (1 + g) / (r - g)
r = required rate of return.
Current stock price = $31.02 million × (1 + 0.12) / (0.13 - 0.12)
= $72.13 million
Finally, we divide the current stock price by the number of shares outstanding to get an estimate of the current stock price per share:
Current stock price per share = $72.13 million / 5.5 million
= $13.11 per share
Therefore, the estimate of the current stock price is $13.11 per share.

Find the area of the surface. The part of the plane 4x + 3y + z = 12 that lies inside the cylinder x2 + y2 = 9
The area of the surface is [tex]\sqrt{\frac{15}{4}}\times \pi[/tex] unit square.
To find the area of the surface, we need to first find the intersection curve between the plane and the cylinder.
From the equation of the cylinder, we know that [tex]x^2 + y^2[/tex] = 9200.
We can substitute [tex]x^2 + y^2[/tex] for [tex]r^2[/tex] and rewrite the equation as [tex]r^2[/tex] = 9200.
Next, we can rewrite the equation of the plane as
z = 12 - 4x - 3y.
Now, we can substitute 12 - 4x - 3y for z in the equation [tex]r^2[/tex] = 9200, giving us:
[tex]x^2 + y^2[/tex] = 9200 - [tex](12 - 4x - 3y)^2[/tex]
Expanding and simplifying, we get:
[tex]x^2 + y^2[/tex] = [tex]16x^2 + 24xy + 9y^2 - 24x - 36y + 884[/tex]
Simplifying further, we get:
[tex]15x^2 + 24xy + 8y^2 - 24x - 36y + 884 = 0[/tex]
We can recognize this as the equation of an ellipse:
To find the area of the surface, we need to find the area of this ellipse that lies within the cylinder.
To do this, we can first find the major and minor axes of the ellipse.
We can rewrite the equation as:
[tex]15(x - \frac{4}{5})^2[/tex] + 8([tex]y[/tex] - [tex]\frac{9}{10}[/tex][tex])^{2}[/tex] = 1
So the major axis has length [tex]2/\sqrt{15}[/tex] unit and the minor axis has length [tex]\frac{2}{\sqrt{8} }[/tex] unit.
The area of the ellipse is then given by:
A = π x ([tex]\frac{1}{2}[/tex] x [tex]\frac{2}{\sqrt{15} }[/tex] x ([tex]\frac{1}{2}[/tex] x [tex]\frac{8}{\sqrt{8} }[/tex])
Simplifying we get:
A = π x ([tex]\sqrt{\frac{2}{15} }[/tex]) x ([tex]\sqrt{\frac{2}{8} }[/tex])
A = π x ([tex]\sqrt{\frac{1}{60} }[/tex])
A = [tex]\sqrt{\frac{15}{4}} \times \pi[/tex] unit square

The radius of a right circular cone is increasing at a rate of 4 inches per second and its height is decreasing at a rate of 3 Inches per second. At what rate is the volume of the cone changing when the radius is 40 inches and the height is 20
inches?
To find the rate of change of the volume of the cone, we need to use the formula for the volume of a cone:
V = (1/3)πr^2h
Taking the derivative of both sides with respect to time, we get:
dV/dt = (1/3)π[2rh(dr/dt) + r^2(dh/dt)]
Substituting the given values:
r = 40 in (radius is increasing at a rate of 4 in/s)
h = 20 in (height is decreasing at a rate of 3 in/s)
dr/dt = 4 in/s
dh/dt = -3 in/s
Plugging these into the formula:
dV/dt = (1/3)π[2(40)(20)(4) + (40)^2(-3)]
dV/dt = (1/3)π[3200 - 4800]
dV/dt = (1/3)π(-1600)
dV/dt = -1681.99 in^3/s
Therefore, the volume of the cone is decreasing at a rate of approximately 1681.99 cubic inches per second when the radius is 40 inches and the height is 20 inches.
To find the rate at which the volume of the cone is changing, we can use the formula for the volume of a cone (V = (1/3)πr^2h) and differentiate it with respect to time (t).
Given:
dr/dt = 4 inches per second (increasing radius)
dh/dt = -3 inches per second (decreasing height)
r = 40 inches
h = 20 inches
First, let's differentiate the volume formula with respect to time:
dV/dt = d/dt[(1/3)πr^2h]
Using the product and chain rules, we get:
dV/dt = (1/3)π(2r(dr/dt)h + r^2(dh/dt))
Now, plug in the given values:
dV/dt = (1/3)π(2(40)(4)(20) + (40)^2(-3))
Simplify:
dV/dt = (1/3)π(6400 - 4800)
dV/dt = (1/3)π(1600)
Finally, calculate the rate:
dV/dt ≈ 1675.52 cubic inches per second
So, the volume of the cone is changing at a rate of approximately 1675.52 cubic inches per second.

A searchlight is shaped like a paraboloid of revolution. if the light source is located 1 feet from the base along the axis of symmetry and the opening is 6 feet across, how deep should the searchlight be?
The searchlight should be 1/3 feet deep at the edge of the opening. Since the paraboloid is a continuous surface, the depth will increase gradually from the edge of the opening to the vertex at (0,0,1).
Determine the depth of the searchlight shaped like a paraboloid of revolution, we need to use the equation for the standard form of a paraboloid of revolution:
z = (x^2 + y^2) / (4f)
where z is the depth, x and y are the horizontal and vertical coordinates, and f is the focal length of the paraboloid.
We know that the light source is located 1 feet from the base along the axis of symmetry, which means that the vertex of the paraboloid is at (0,0,1).
We also know that the opening is 6 feet across, which means that the horizontal distance from one side of the opening to the other is 3 feet.
Using this information, we can find the value of f:
f = (d/2)^2 / 2r
where d is the diameter of the opening (6 feet), and r is the radius of curvature at the vertex (1 foot).
f = (6/2)^2 / 2(1) = 4.5 feet
Now we can plug in the values for x, y, and f to solve for z:
z = (x^2 + y^2) / (4f)
z = (x^2 + y^2) / (4(4.5))
z = (x^2 + y^2) / 18
Since the opening is 6 feet across, we know that the maximum value of x is 3 feet. Therefore, we can use the maximum value of y (also 3 feet) to find the depth at the edge of the opening:
z = (3^2 + 3^2) / 18
z = 6/18
z = 1/3 feet
So the searchlight should be 1/3 feet deep at the edge of the opening. However, since the paraboloid is a continuous surface, the depth will increase gradually from the edge of ×the opening to the vertex at (0,0,1).

5. To eliminate the need for arctan, we can use the Pythagorean identity sin^2(θ) + cos^2(θ) = 1. Substitute the sine and cosine ratios we found earlier:
((y-k) / r)^2 + ((x-h) / r)^2 = 1
6. Simplify the equation by multiplying both sides by r^2:
(y-k)^2 + (x-h)^2 = r^2
You'll notice that this equation is the same as the one we found in step 3, confirming that the point P lies on the circle. You've now solved the point circle problem without using arctan, by employing the Pythagorean theorem and trigonometric ratios instead.

If Yasmina expects to give 200 rides, she should use Choose. Pollys Ponies or Sally's Saddles
Based on the given information, Yasmina should use Sally's Saddles if she expects to give 200 rides and wants to make the most profit.
To determine which company Yasmina should use to offer horseback rides at her school's Spring Fair, we need to compare the costs and revenues associated with each option.
First, let's consider Polly's Ponies. They charge $100 for a small pony and Yasmina can charge children $2 for a ride. To break even with this option, Yasmina would need to give 50 rides ($100 / $2 per ride). If she expects to give 200 rides, she would earn $400 in revenue ($2 per ride x 200 rides) and have a profit of $300 ($400 revenue - $100 rental fee).
Next, let's consider Sally's Saddles. They charge $240 for a larger horse and Yasmina can charge children $3 for a ride. To break even with this option, Yasmina would need to give 80 rides ($240 / $3 per ride). If she expects to give 200 rides, she would earn $600 in revenue ($3 per ride x 200 rides) and have a profit of $360 ($600 revenue - $240 rental fee).
Therefore, if Yasmina wants to make the same amount of profit regardless of which company she uses, she would need children to take a total of 125 rides ((($240 rental fee for Sally's Saddles - $100 rental fee for Polly's Ponies) / ($3 per ride - $2 per ride)). If she expects to give 200 rides, she should use Sally's Saddles since she will make a higher profit of $360 compared to $300 with Polly's Ponies.

Convert Sin7A * Cos3A into sum or difference of sine or cosine
Using the identity: sin(A + B) = sin A cos B + cos A sin B, we can rewrite the expression as follows:
Sin 7A * Cos 3A = (sin 4A + sin 10A)/2 * (cos 2A + cos A)/2
Expanding this expression using the same identity, we get:
= (sin 4A * cos 2A + sin 4A * cos A + sin 10A * cos 2A + sin 10A * cos A)/4
Now, using the identity sin 2A = 2 sin A cos A, we can simplify further:
= (1/2) sin 2A * cos 2A + (1/2) sin 2A * cos 8A + (1/2) sin 6A * cos 2A + (1/2) sin 6A * cos 8A
Therefore, Sin 7A * Cos 3A can be written as:
(1/2) sin 2A * cos 2A + (1/2) sin 2A * cos 8A + (1/2) sin 6A * cos 2A + (1/2) sin 6A * cos 8A

The coordinates of the point are (7,0).
How to solve for the coordinatesdistance from (-3,-5) to (x,y) = 2 * distance from (x,y) to (9,-8)
Using the distance formula, we can write this equation as:
√[(x - (-3))^2 + (y - (-5))^2] = 2 * √[(9 - x)^2 + (-8 - y)^2]
Simplifying this equation, we get:
[tex](x + 3)^2 + (y + 5)^2 = 4[(9 - x)^2 + (-8 - y)^2][/tex]
Expanding and simplifying further, we get:
[tex]17x + 16y = 119[/tex]
So the coordinates of the point on the directed line segment from (-3,-5) to (9,-8) that partitions the segment into a ratio of 2 to 1 are:
x = (119 - 16y)/17
y = any value (since we can choose any value of y and then calculate x using the equation above)
For example, if we choose y = 0, then we get:
x = (119 - 16(0))/17 = 7
So the coordinates of the point are (7,0).

An art studio offers classes for painting and pottery. Each painting class is 1
hour long. Each pottery class is 1. 5 hours long. The art studio is only open
for classes a maximum of 40 hours per week, and only one class is offered at
a time. Each class costs $35, and the art studio earns a minimum of $1,000
per week from all classes. Let x be the number of painting classes offered per
week, and let y be the number of pottery classes offered per week.
The art studio can offer a maximum of 8 painting classes and 5 pottery classes per week, while still meeting the time constraint and earning at least $1000 per week.
To find the maximum number of classes the art studio can offer per week, we need to set up an equation based on the time constraint.
Let's assume that the studio offers x painting classes and y pottery classes per week. Since each painting class is 1 hour long and each pottery class is 1.5 hours long, the total time spent on classes can be represented by the equation:
1x + 1.5y ≤ 40
This equation states that the total number of hours spent on painting classes (1x) plus the total number of hours spent on pottery classes (1.5y) must be less than or equal to 40 hours per week.
To find the minimum revenue the art studio can earn per week, we can set up another equation based on the cost of each class and the minimum revenue requirement.
Let's assume that each painting or pottery class costs $35. Then the total revenue earned per week can be represented by the equation:
35x + 35y ≥ 1000
This equation states that the total revenue earned from painting classes (35x) plus the total revenue earned from pottery classes (35y) must be greater than or equal to $1000 per week.
Now we have two equations:
1x + 1.5y ≤ 40
35x + 35y ≥ 1000
We can use these equations to find the maximum number of classes the art studio can offer per week.
To do this, we can graph the two equations on the same coordinate plane and find the point where they intersect.
When we do this, we get the point (x, y) = (8, 16/3).
This means that the art studio can offer a maximum of 8 painting classes and 16/3 (or approximately 5.33) pottery classes per week, while still meeting the time constraint and earning at least $1000 per week.
Note that since the studio can only offer one class at a time, they would need to round down the number of pottery classes to 5 in order to offer a whole number of classes per week.

Victoria has $200 of her birthday gift money saved at home, and the amount is modeled by the function h(x) = 200. She reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1. 05)x−1. Explain how Victoria can combine the two functions to model the total amount of money she will have in her bank account as interest accrues after she deposits her $200. Justify your reasoning.
WILL GIVE BRANLIEST
The reasoning behind this is that the initial amount (h(x)) is multiplied by the interest growth factor (s(x)) to calculate the total amount with interest over time.
To model the total amount of money Victoria will have in her bank account as interest accrues after depositing her $200, you can combine the two functions h(x) and s(x). The given functions are h(x) = 200 and s(x) = (1.05)^x−1.
First, note that s(x) represents the growth factor of the interest, which is 5% (1.05) compounded annually. To find the total amount after x years, you need to multiply the initial amount by the growth factor raised to the power of x.
So, the combined function T(x) can be written as T(x) = h(x) * s(x).
Substitute the given functions into the combined function:
T(x) = (200) * ((1.05)^x−1)
This function, T(x), models the total amount of money Victoria will have in her bank account after x years with interest accrued on her $200 deposit. The reasoning behind this is that the initial amount (h(x)) is multiplied by the interest growth factor (s(x)) to calculate the total amount with interest over time.
