The revenue, in dollars, of a company that produces video game systems can be modeled by the expression 5x2 + 2x – 80. The cost, in dollars, of producing the video game systems can be modeled by 5x2 – x + 100, where x is the number of video game systems sold. If profit is the difference between the revenue and the cost, what expression represents the profit?
Answer: 3x-180
Step-by-step explanation:
Given: Expression for Revenue = \(5x^2 + 2x - 80\)
Expression for Cost = \(5x^2- x + 100\)
If profit is the difference between the revenue and the cost then the expression for profit will be:
Profit = Revenue - cost
\(=5x^2 + 2x - 80-(5x^2- x + 100)\\\\=5x^2 + 2x - 80-5x^2+x-100\ \ [\text{Multiply ' - ' sign inside the bracket}]\\\\=2x+x-80-100\\\\=3x-180\)
Hence, the expression represents the profit is 3x-180 .

Find the slope of the line passing through the pair of points.any vertical lineOm = 1Om = 0m =undefinedO cannot be determined
m = undefined
For a vertical line, we have the same point of x-axis.
What this mean is that there is no change on the x-axis.
An example is shown below;
Find the slope of the line AB;
We can see the line AB as a vertical line
Mahematically, the formula for the slope of a line is given as;
\(m\text{ = }\frac{y_2-y_1}{x_2-x_1}\)But in the case of a vertical line;
\(x_2=x_1\)So what this mean is that, we rewrite our formula for the slope as;
\(m\text{ = }\frac{y_2-y_1}{x_2-x_2}\text{ = }\frac{y_2-y_1}{0}\)But since the division of any number with zero as the denominator is 'undefined"
The slope m in this case is undefined

The maximum revenue possible in this situation is 15625/A dollars, where A is the coefficient in the quadratic equation.
To find the maximum revenue possible in this situation, we can use the concept of vertex or the vertex form of a quadratic equation.
The revenue equation is given by R = -Ax^2 + 250x, where A is a constant coefficient.
The maximum revenue occurs at the vertex of the parabolic curve represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a and b are the coefficients of the quadratic equation.
In this case, a = -A and b = 250. Plugging in these values, we get:
x = -250 / (2 * (-A))
= 125 / A
To find the maximum revenue, we substitute this value of x into the revenue equation:
R = -A * (125 / A)^2 + 250 * (125 / A)
= -A * (15625 / A^2) + (31250 / A)
= -15625 / A + 31250 / A
= 15625 / A
The maximum revenue is given by 15625 / A. The value of A is not specified in the question, so we cannot determine the exact maximum revenue without knowing the value of A. However, we can say that the maximum revenue increases as A decreases.

A reproductive clinic had a success rate of 25% of patients with live births in 2008. They want to update their success rate (the proportion of live births) for 2020. If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval? Round your answer up to the nearest integer.
Answer:
They should sample the results of 1990 patient results.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).
The margin of error is of:
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
A reproductive clinic had a success rate of 25% of patients with live births in 2008.
This means that \(\pi = 0.25\)
99% confidence level
So \(\alpha = 0.01\), z is the value of Z that has a p-value of \(1 - \frac{0.01}{2} = 0.995\), so \(Z = 2.575\).
If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval?
They should sample n patients.
n is found for \(M = 0.025\). So
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
\(0.025 = 2.575\sqrt{\frac{0.25*0.75}{n}}\)
\(0.025\sqrt{n} = 2.575\sqrt{0.25*0.75}\)
\(\sqrt{n} = \frac{2.575\sqrt{0.25*0.75}}{0.025}\)
\((\sqrt{n})^2 = (\frac{2.575\sqrt{0.25*0.75}}{0.025})^2\)
\(n = 1989.2\)
Rounding up:
They should sample the results of 1990 patient results.
tanx(1+cos2x)=sin2x prove the identity
Using double angle identity, we are able to prove tan(x)(1 + cos(2x)) = sin(2x).
What is the prove of the given identity?To prove the identity tan(x)(1 + cos(2x)) = sin(2x), we can start by using trigonometric identities to simplify both sides of the equation.
Starting with the left-hand side (LHS):
tan(x)(1 + cos(2x))
We know that tan(x) = sin(x) / cos(x) and that cos(2x) = cos²(x) - sin²(x). Substituting these values, we get:
LHS = (sin(x) / cos(x))(1 + cos²(x) - sin²(x))
Next, we can simplify the expression by expanding and combining like terms:
LHS = sin(x) / cos(x) + sin(x)cos²(x) / cos(x) - sin³(x) / cos(x)
Simplifying further:
LHS = sin(x) / cos(x) + sin(x)cos(x) - sin³(x) / cos(x)
Now, let's work on the right-hand side (RHS):
sin(2x)
Using the double angle identity for sine, sin(2x) = 2sin(x)cos(x).
Now, let's compare the LHS and RHS expressions:
LHS = sin(x) / cos(x) + sin(x)cos(x) - sin³(x) / cos(x)
RHS = 2sin(x)cos(x)
To prove the identity, we need to show that the LHS expression is equal to the RHS expression. We can combine the terms on the LHS to get a common denominator:
LHS = [sin(x) - sin³(x) + sin(x)cos²(x)] / cos(x)
Now, using the identity sin²(x) = 1 - cos²(x), we can rewrite the numerator:
LHS = [sin(x) - sin³(x) + sin(x)(1 - sin²(x))] / cos(x)
= [sin(x) - sin³(x) + sin(x) - sin³(x)] / cos(x)
= 2sin(x) - 2sin³(x) / cos(x)
Now, using the identity 2sin(x) = sin(2x), we can simplify further:
LHS = sin(2x) - 2sin³(x) / cos(x)
Comparing this with the RHS expression, we see that LHS = RHS, proving the identity.

Suppose a railroad is 2 kilometers and it expands on a hot day by 11 centimeters in length. Approximately how many meters would the center of the rail rise above the ground?
the center of the rail would rise above the ground by approximately 0.24 meters, or 24 centimeters.
How to solve?
To solve this problem, we can use the formula for the change in length of an object due to thermal expansion:
ΔL = αLΔT
where ΔL is the change in length, α is the coefficient of thermal expansion, L is the original length, and ΔT is the change in temperature.
We know that the original length of the railroad is 2 kilometers, or 2000 meters, and that the change in length is 11 centimeters, or 0.11 meters. We can also assume that the change in temperature is due to a hot day, which might raise the temperature by 10°C.
The coefficient of thermal expansion for steel, which is commonly used in railroad tracks, is about 1.2 x 10²-5 /°C.
Substituting these values into the formula, we get:
0.11 meters = (1.2 x 10²-5 /°C) x 2000 meters x 10°C
Simplifying this expression, we get:
0.11 meters = 0.24 meters
So the center of the rail would rise above the ground by approximately 0.24 meters, or 24 centimeters.

Step-by-step explanation:
Using the normal curve to approximate a sampling distribution:
For a sample size n and a proportion n, the normal curve can be used if:
\(np \geq 10\) and \(n(1-p) \geq 10\)
Option a:
\(np = 35*0.8 = 28 > 10\)
\(n(1-p) = 35*0.2 = 7 < 10\)

Option b:
\(np = 65*0.9 = 58.5 > 10\)
\(n(1-p) = 65*0.1 = 6.5 < 10\)
So option b cannot be used.
Option c:
\(np = 65*0.8 = 52 > 10\)
\(n(1-p) = 65*0.2 = 13 > 10\)
So option c can be used, and is the answer

A retired goverment officer will get a 10% increase in his monthly pension from july 2009 he spend 50% of his pension on food items
He spends 50% of his pension on food items, he will be spending 770 on food items during the next month.
What is percentage?
Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".
If the retired government officer will receive a 10% increase in his monthly pension from July 2009, then his new monthly pension amount will be 110% of his current monthly pension. In other words, his new pension amount will be 1.1 times his current pension amount.
Let's call the retired government officer's current monthly pension amount "P". Then, his new monthly pension amount will be:
1.1P
We know that the retired government officer spends 50% of his pension on food items, or 0.5P. If he currently spends 700 on food items, we can set up the following equation:
0.5P = 700
Solving for P, we get:
P = 1400
Now, we can plug this value into the equation for the retired government officer's new monthly pension amount:
1.1P = 1.1(1400) = 1540
Therefore, the retired government officer will be receiving a new monthly pension amount of 1540. Since he spends 50% of his pension on food items, he will be spending:
0.5(1540) = 770

Answer:
y = - x + 4
Step-by-step explanation:
x + y = 6
y = - x + 6
Slope= -1
Use the same slope since the two lines are parallel to each other.
Point-slope formula:
y - 8 = -1 (x - - 4)
y - 8 = -1 (x + 4)
y - 8 + 8 = -x - 4 + 8
y = - x + 4 (Slope-intercept form)
An equation of the line that passes through the point (−4,8) and is parallel to the line x+y=6 could be y = - x + 4 .
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
WE have
x + y = 6
y = - x + 6
Slope= -1
Now, Use the same slope since the two lines are parallel to each other.
Point-slope formula:
y - 8 = -1 (x - - 4)
y - 8 = -1 (x + 4)
y - 8 + 8 = -x - 4 + 8
y = - x + 4 (Slope-intercept form)

Given, triangle DHS has the coordinates D(-5, 1), H(-4, 5) and S(-1, 2). Now, we have to find the coordinates of D'H'S' if DHS is translated 2 units right and 1 unit down.
A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation. In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved.
To translate the point P(x,y), 'a' units right and 'b' units down, use P′(x+a,y-b).
Now, let's proceed to solve the question according to above listed points accordingly.
D(-5, 1), H(-4, 5) and S(-1, 2), these coordinates are translated 2 units right and 1 unit down. So, we will simply add 2 to the x-coordinate of the points and will subtract 1 from the y-coordinate.
Let's translate D, H and S accordingly into D', H' and S'.
D(-5,1)⇒ D(-5+2, 1-1)⇒ D'(-3,0)
H(-4,5)⇒ H(-4+2, 5-1)⇒ H'(-2,4)
S(-1,2)⇒ S(-1+2, 2-1)⇒ S'(1,1)
Therefore, the new coordinates after translation are D'(-3,0), H'(-2,4) and S'(1,1) respectively.
