A university is trying to determine what price to charge for tickets to football games. At a price of $18 per ticket, attendance averages 40,000 people per game. Every decrease of $3 adds 10,000 people to the average number. Every person at the game spends an average of $4.50 on concessions. What price per ticket should be charged in order to maximize revenue? How many people will attend at that price?

The method to find the other x-intercept for the function f(x) = ax² + bx + c is given in the explanation below the answer.

The other x-intercept is; ((-b/2a - 3), 0)

We are given the equation of the function;

f(x) = ax² + bx + c

where a, b and c are real numbers and non - zero

Now, this is a quadratic equation that has 2 roots and it means there will be two x-intercepts.

Also, in quadratic equations, the formula to find the x-coordinate of the line of symmetry of the graph is;

x = -b/2a

The line of symmetry divides the graph curve into 2 equal parts at the vertex. This means the two x - intercepts will be the same distance from the x-coordinate of the vertex or line of symmetry but on opposite sides.

Thus, if one x-intercept is at ((-b/2a + 3), 0), then the other coordinate using the line of symmetry reason above is; ((-b/2a - 3), 0)

took the test 100% 4.08 Quiz: Finding the Volume of Rectangular Prisms and Problem Solving

The student's expression is simplified by dividing 1.64 by 100 then expressing the result in scientific notation as 1.64  imes 10⁻².

The student's question involves simplifying a mathematical expression that uses scientific notation. The expression is 1.64 times 10⁰ divided by 2.0 times 10². Here's a step-by-step breakdown:

Identify the powers of ten: The denominator has 10 to the power of 2, which is 10 squared or simply 100. The numerator has 10 to the power of 0, which equals 1.

Simplify the expression: Divide 1.64 by 100 (2.0 times 10²), which gives a result of 0.0164.

Express in scientific notation: 0.0164 can be written as 1.64 times 10⁻².

We need a table to do this. 3 rows and 3 columns. Across the top the columns are number of liters, % alcohol, and total. We will label the first row stuff with alcohol, the second row stuff with water, and the third row will be the mix of alcohol and water. In the first column we will put an x for alcohol since we don't know how much alcohol we have in the mix. In the second column we will put the decimal equivalent of the percent alcohol, which is .18. In the total column we will put the product of those 2, which is .18x. Now for the second row, water. We will put a y in the first column since we don't know how much water we have in the mix. In the second column we will put a 0, since water doesn't have any alcohol in it. In the third column we will put the product of the 2 which will be 0. In the third row, the mix row, we put a 10 since we want 10 L of this mix. We will put the decimal equivalent of how much alcohol we want in this mix which is .12. In the total column we put the product of those 2 which is 1.2. Since we are adding the alcohol and the water, x and y, to get a total of 10, this is our first equation. x+y=10. In the total column we will add the percent alcohol in the alcohol and the water to get 1.2. .18x + 0 = 1.2, or just .18x = 1.2. Let's divide both sides by .18 to find the amount of alcohol is in this mix. We get 6 2/3 liters of alcohol. If there is a total of 10 L of this mix, 10 - 6 2/3 = water, and the amount of water then is 3 1/3 L.

To calculate the six-month emergency fund, we first determined the monthly net income after deductions from the gross monthly pay. Then, we found that 30% of the net income goes towards housing and fixed expenses. Multiplying this expense by six gives the total emergency fund needed, which is $2,848.20.

To calculate the amount needed for a six-month emergency fund, we first need to determine the monthly take-home pay after all deductions. The student earns $13.70 per hour and works 40 hours a week. Deductions include FICA (7.65%), federal tax withholding (11.55%), and state tax withholding (8.35%).

First, calculate the gross monthly income: $13.70/hr * 40 hrs/wk * 4 weeks/mo = $2,184/month.

Next, calculate total deductions: FICA (7.65% of $2,184) + Federal Tax (11.55% of $2,184) + State Tax (8.35% of $2,184) = $166.97 + $252.34 + $182.36 = $601.67.

Now calculate the net monthly income: $2,184 - $601.67 = $1,582.33.

The student's housing and fixed expenses are 30% of the net income, which amounts to $474.70/month. Therefore, for a six-month emergency fund, the student would need:

$474.70 * 6 months = $2,848.20 saved.

To save for a six-month emergency fund, you must first calculate your net monthly pay after deductions from your salary, which is determined to be $1,588.12. Then calculate 30% of this for your monthly fixed expenses, and finally, multiply that amount by six to determine the total savings required for the emergency fund, which amounts to $2,858.64.

To calculate how much you need to save for an emergency fund, we first need to determine your monthly take-home pay after deductions. Your gross pay per week is $13.70 per hour multiplied by 40 hours, which equals $548. Your gross pay per month is then $548 times 4 weeks, totaling $2,192. We will then subtract the deductions: FICA (7.65%), federal tax (11.55%), and state tax (8.35%). Let's calculate each:

FICA: $2,192 x 7.65% = $167.68

Federal Tax: $2,192 x 11.55% = $253.17

State Tax: $2,192 x 8.35% = $183.03

Your total deductions are $167.68 + $253.17 + $183.03 = $603.88.

So, your net monthly pay is $2,192 - $603.88 = $1,588.12.

Next, we calculate your fixed expenses which are 30% of your net income: $1,588.12 x 30% = $476.44.

To determine the amount needed for a six-month emergency fund, you multiply your monthly fixed expenses by six:

$476.44 x 6 = $2,858.64.

Therefore, you need to save $2,858.64 for your emergency fund.

Answer:

the answer is C: y = -0.875x^2 - 3.956x + 20.179

Step-by-step explanation:

To predict the temperature during the sixth hour, we need to find the regression equation of the line that best fits the given data. Using the slope and y-intercept, we can substitute x = 6 into the equation to find the predicted temperature, which is -3.42.

To predict the temperature during the sixth hour using the regression equation, we need to find the equation of the line that best fits the given data. The regression equation is of the form y = mx + b, where m is the slope of the line and b is the y-intercept.

First, we need to calculate the slope (m) and the y-intercept (b) using the given data points. Then, we can substitute x = 6 into the equation to find the predicted temperature.

Using the formula for the slope (m) and the y-intercept (b), we find that m = -5.07 and b = 22.2. Substituting x = 6 into the regression equation, we get y = -5.07(6) + 22.2 = -3.42. Therefore, the predicted temperature during the sixth hour is -3.42.

We have a circle A and a line segment BQ is passing through the circle A such that it forms a triangle ABQ.

From the diagram, we have some information about the angles of triangle ΔABQ as follows :-

angle QAB = 36 degrees and angle BAQ = 54 degrees.

We know about the Triangle Sum theorem which states "The sum of all interior angles of any triangle is 180 degrees".

We can use this theorem to find the third angle of the triangle ΔABQ.

∠ABQ + ∠BQA + ∠QAB = 180 degrees

∠ABQ + 54° + 36° = 180°

∠ABQ + 90° = 180°

∠ABQ = 180° - 90°

∠ABQ = 90 degrees

If any line makes a right angle with the radius of any circle, then this line must be a tangent to that circle.

So, BQ would be a tangent line because angle ∠ABQ = 90 degrees. Hence, option A is correct.

When no specific speed limit is posted, the default speed limit applies. These defaults are set by local or state law and can vary. Drivers must adhere to these limits and drive safely for conditions.

In most areas, when specific traffic speed limit signs are not posted, what's known as the default speed limit applies. These default speed limits are not posted on signs and instead are set by local or state law. It's important to stay aware of these limits in different areas, as they can vary. For instance, in many cities, the default speed limit is 25 mph unless otherwise posted. However, it should be noted that these default limits may not protect you from being pulled over if the police deem your speed unsafe for the current conditions. Thus, it's recommended to always drive at a speed that is appropriate for the conditions, even if you are technically within the speed limit.

Final answer:

To find the equivalent numerator, we can multiply both sides of the equation by the denominator.

Explanation:

The equivalent numerator can be found by multiplying both sides of the equation by the denominator, which is x³y². This will cancel out the denominator on the right side. The result will be the equivalent numerator.

For example, if we have the equation 2x³y² = 6, we can multiply both sides by x³y² to get rid of the denominator:

equation * (x³y²) = 6 * (x³y²)
The x³y² on the left side will cancel out, leaving us with the equivalent numerator:

equivalent numerator = 6 * (x³y²)
So, the equivalent numerator is 6x³y².
