To find when the daily ticket sales will peak, we need to find the maximum value of the quadratic equation [tex]N &= -0.3x^2+9x+13[/tex].
How to calculate no. of ticket solds and peak ticket sales?
Part 1:
The maximum value of a quadratic equation of the form [tex]y &= ax^2 + bx + c[/tex] occurs at [tex]x = \frac{-b}{2a}[/tex]. So in our case, the peak day will be at:
[tex]x &= \frac{-9}{2(-0.3)} = 15[/tex]
Therefore, the peak will be reached 15 days after the concert was first announced.
Part 2:
To find the number of tickets sold on that day, we substitute x=15 into the equation [tex]N &= -0.3x^2+9x+13[/tex]:
[tex]N &= -0.3(15)^2 + 9(15) + 13 = 67[/tex]
So the number of tickets sold on the day of the peak will be 67.

Hey- can someone help me with theese 2 questions- i did them yestr and it said that they were wrong?
Answer: 1) C. 1.75
2) C. 5.25
Step-by-step explanation:
For this first question, the answer is C. 1 3/4
First, you will need to calculate how many hours the 3/4-hour students studied versus the 1/4-hour students.
3/4 students: 3/4 · 3 = 9/4
1/4 students: 1/4 · 2 = 2/4
9/4 - 2/4 = 7/4 = 1 3/4
Therefore, your answer for the first question is C.
For the second question, the answer is C
We must calculate how many hours each group of students studied, then add them together. You can add or multiply in this situation.
1/4 students: 1/4 · 2 = 2/4 (No need for simplifying until the end.)
1/2 students: 1/2 · 5 = 5/2
3/4 students: 3/4 · 3 = 9/4
Now, let's change the 5/2 so we can add it to the other fractions.
5/2 ·2 = 10/4
Let's add.
2/4 + 10/4 + 9/4 = 21/4
Simplify.
21/4 = 5 1/4.
Therefore, answer choice C is correct.

Sally Brown bought a house with a 10% adjustable rate mortgage for 20 years. She was paying $9.66 monthly per thousand on her original loan. At the end of 4 years she owes the bank $55,000.00. Interest has now gone up to 12%, the bank can renew the mortgage at this rate or Sally can pay the full $55,000.00. Sally renews the mortgage and will pay $11.02 monthly per thousand on this loan.
What is the amount of the old and new monthly payment? What is the percent of increase in her new monthly payment (to the nearest tenth)?
old payment = $
new payment = $
% increase
The old payment is $96.60, and the new payment is $110.20. The percent increase in her new monthly payment is 14.1%.
To calculate the old payment, we multiply the original loan amount by the monthly payment per thousand, which gives us $9.66 x 55 = $531.30.
To calculate the new payment, we divide the renewed loan amount by 1000 and multiply it by the monthly payment per thousand, which gives us $11.02 x 55 = $606.10.
To calculate the percent increase, we use the formula: ((new payment - old payment) / old payment) x 100. Substituting the values, we get ((606.10 - 531.30) / 531.30) x 100 = 14.1%. Therefore, the percent increase in her new monthly payment is 14.1%.

Elephants are born with tusks and their tusks grow 4 inches a year. A 1 year old elephants tusk measured 5 inches. Write a linear equation that represents the situation how long will the elephants tusk be at 6 years old
Answer: y = 4x + 1, 25 inches at 6 years old
Step-by-step explanation:
Our y-intercept will be 1 (5 inches at a year old - 4 inches per year = 1) with a slope of 4 (4 inches a year). Our equation will look like this:
y = 4x + 1
Next, to solve for the length of the tusk at 6 years old, we will input this value of 6 and solve.
y = 4x + 1 = 4(6) + 1 = 25 inches
See attached for a graph.
We can also check our work using a different method.
6 years - 1 year = 5 years
5 years * 4 inches a year = 20 inches
20 inches + current 5 inches = 25 inches at 6 years

suppose you add 1 identical room to a pair of houses. the two houses are identical except for square footage. how much does lprice increase for a house with 4000 sqft compared to a house with 1000 sqft?
When adding one identical room to a pair of houses, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.
What is the basis of this problem?
We have two houses, one with a 4000 square foot floor plan and another with a 1000 square foot floor plan. Both of them are identical, and each of them is expected to receive an additional identical room. We must determine how much the price of the house with the 4000 square foot floor plan will increase compared to the house with the 1000 square foot floor plan when both of these are completed.
Let's start by identifying the amount of money needed to construct each house. The amount of money needed to construct the house with the 4000 square foot floor plan is $300,000, and the amount of money required to build the house with the 1000 square foot floor plan is $150,000.The cost of building per square foot in this case is therefore $75/sqft.
As a result, the price for a 4000 sqft house is: $75/sqft × 4000 sqft = $300,000On the other hand, the cost of constructing a 1000 sqft house is:$75/sqft × 1000 sqft = $75,000When each house gets an additional identical room, the increase in the cost of the room is $50,000. As a result, the price of the house with the 4000 square foot floor plan will increase by 4 times, or $200,000, whereas the price of the house with the 1000 square foot floor plan will increase by one, or $50,000. As a result, the price of a 4000 sqft house will be $300,000 + $200,000 = $500,000, whereas the price of a 1000 sqft house will be $150,000 + $50,000 = $200,000.
When we compare these two values, we obtain the following outcome: Suppose you add 1 identical room to a pair of houses. The two houses are identical except for square footage.
When we compare the two values, we get the following result: $500,000 - $200,000 = $300,000
Therefore, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.

The capitalized costs for 2017 is $55,000.
Capitalizing means adding the cost of an asset to its book value or cost basis. Not all costs can be capitalized.
Generally, only costs that increase an asset's useful life or productive capacity should be capitalized.
In this case, the building and truck were purchased in 2015 and have been capitalized.
The following costs incurred in 2017 should be analyzed to determine whether they should be capitalized or expensed:
Painting the building for $5,000 - This cost does not increase the useful life or productive capacity of the building.
It is considered a repair and maintenance expense and should be expensed.
Installing new windows in the building for $10,000 - This cost improves the building's insulation and prevents leaking.
It is considered a capital improvement that extends the useful life of the building. Therefore, it should be capitalized.
Installing a new conveyor system for $40,000 - This cost increases the productive capacity of the company's operations. It is considered a capital expenditure and should be capitalized.
Repainting the delivery truck for $1,000 - This cost does not increase the useful life or productive capacity of the truck. It is considered a repair and maintenance expense and should be expensed.
Installing a hydraulic lift system on the truck for $5,000 - This cost allows better handling of large loads and increases the productive capacity of the truck. It is considered a capital expenditure and should be capitalized.
Overhauling the truck's engine for $4,000 - This cost is a repair and maintenance expense and should be expensed.
Therefore, the capitalized costs for 2017 are
$10,000 (new windows in the building) + $40,000 (new conveyor system) + $5,000 (hydraulic lift system on the truck) = $55,000.

A soccer player is going to kick a soccer ball from one corner of a field to the opposite corner. If the field is 80 yards long and 60 yards wide, how far will the soccer player have to kick the ball?
Answer: Assuming the field is rectangular, the distance between the two corners diagonally can be calculated using the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
In this case, the length and width of the field form the two sides of the right triangle, and the diagonal is the hypotenuse.
So, using the Pythagorean theorem:
Diagonal^2 = Length^2 + Width^2
Diagonal^2 = 80^2 + 60^2
Diagonal^2 = 6400 + 3600
Diagonal^2 = 10000
Diagonal = √10000
Diagonal = 100 yards
Therefore, the soccer player will have to kick the ball 100 yards to reach the opposite corner of the field.

Sarah launches a snowball at
a rate of 16 feet per second
from a hill that is 32 feet off
the ground.
When does the
snowball hit the
ground?
What is the maximum
height the snowball
reaches?
Step-by-step explanation:
We can use the kinematic equations of motion to solve this problem. Let's assume the initial velocity of the snowball is 16 feet per second and its initial height is 32 feet. Also, we know that the acceleration due to gravity is -32.2 feet per second squared (assuming downward direction as negative).
To find out when the snowball hits the ground, we can use the equation:
h = 32 + 16t - 16t^2
where h is the height of the snowball at time t. We want to find the value of t when h = 0 (since the snowball hits the ground at that point). Therefore, we can rewrite the equation as:
16t^2 - 16t - 32 = 0
Dividing both sides by 16, we get:
t^2 - t - 2 = 0
Solving for t using the quadratic formula, we get:
t = (1 ± √(1 + 8))/2
t = 2 seconds or -1 second
Since time cannot be negative, the snowball hits the ground after 2 seconds.
To find the maximum height the snowball reaches, we can use the fact that the maximum height occurs at the vertex of the parabolic trajectory. The x-coordinate of the vertex is given by:
t = -b/2a
where a and b are the coefficients of the quadratic equation. In this case, a = 16 and b = -16, so:
t = -(-16)/(2*16) = 0.5 seconds
To find the corresponding height, we can substitute t = 0.5 seconds into the equation for h:
h = 32 + 16(0.5) - 16(0.5)^2
h = 36 feet
Therefore, the maximum height the snowball reaches is 36 feet.

Angle b has a measure between 0° and 360° and is coterminal with a â€""865° angle. what is the measure of angle b? 110° 115° 210° 215°
An angle that is coterminal with -865° and has a measure between 0° and 360° is 75°. Since Angle b is coterminal with this angle, we can conclude that the measure of Angle b is 75°.
We must locate an angle that is coterminal with the -865° angle and has a measure between 0° and 360° in order to determine the size of angle b.
To do this, we can add or remove 360-degree multiples until we have an angle that is coterminal with -865° and is between 0° and 360°.
-865° + 360° = -505° (not between 0° and 360°)
-865° + 2(360°) = -145° (not between 0° and 360°)
-865° + 3(360°) = 75° (between 0° and 360°)
As a result, an angle with a measure between 0° and 360° that is coterminal with -865° is 75°. We can infer that Angle b's measure is 75° because it contaminates with this angle.

When it comes to the number of carrots that remain without being given to a bunny, we need to calculate it using the following formula:Total number of whole carrots − (Number of whole carrots each bunny gets × Total number of bunnies) = Number of whole carrots that remain without being given to a bunnyUsing the figures from the above calculations, the computation will be as follows:3,939 − (7,878 × 5) = 3,939 − 39,390 = -35,451. Therefore, the number of whole carrots that remain without being given to a bunny is -35,451. However, since the answer must be a whole number, we can round this up to 0 carrots. This implies that all of the carrots were given to the bunnies.
