Answer: p = $100, R = $25,000
Step-by-step explanation:
The maximum is the y-value of the Vertex.
Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x: [tex]x=\dfrac{-b}{2a}[/tex]
R(p) = -2.5p² + 500p
a=-2.5 b=500
[tex]p=\dfrac{-(500)}{2(-2.5)}[/tex]
[tex]=\dfrac{-500}{-5}[/tex]
[tex]=100[/tex]
Step 2: Find the maximum by plugging the p-value (above) into the given equation.
R(100) = -2.5(100)² + 500(100)
= -25,000 + 50,000
= 25,000
The price that maximizes revenue for the software package is $100, and the maximum revenue attainable is $25,000 based on the given revenue function R(p).
To find the price that maximizes revenue and the maximum revenue itself, we can use the given revenue function R(p) = -2.5p² + 500p.
To find the price that maximizes revenue, we need to find the vertex of the quadratic function, as the vertex represents the maximum point. The formula for the x-coordinate (price in this case) of the vertex of a quadratic function in the form of ax² + bx + c is given by:
x_vertex = -b / (2a)
In our case, a = -2.5 and b = 500:
x_vertex = -500 / (2 * (-2.5))
x_vertex = -500 / (-5)
x_vertex = 100
So, the price that maximizes revenue is $100.
To find the maximum revenue, we need to substitute this price back into the revenue function:
R(100) = -2.5(100)² + 500(100)
R(100) = -2.5 * 10000 + 50000
R(100) = -25000 + 50000
R(100) = 25000
Therefore, the maximum revenue is $25,000.
So, the price that maximizes revenue is $100, and the maximum revenue is $25,000.

A company is selling two types of treadmills. Treadmill x sells for $750 and treadmill y sells for $900. Three times the number of treadmill y sold must be less than or equal to twice the number of treadmill x sold. The company has at most 100 treadmills to sell. What is the maximum revenue that the company can make from the treadmill sales?
$75,000
$81,000
$84,000
$90,000
Answer:
Option B is correct
The maximum revenue that the company can make from the treadmill sales is, $81,000
Step-by-step explanation:
Let x represent the number of treadmill x sold and y represents the number of treadmill y sold
As per the statement: Three times the number of treadmill y sold must be less than or equal to twice the number of treadmill x sold.
⇒[tex]3y\leq 2x[/tex] ......[1]
Also, it is given that the company has at most 100 treadmills to sell.
⇒[tex]x+y\leq 100[/tex]
using a graph tool for equation [1] and [2] as shown in figure given below;
⇒ the solution is the shaded area
The maximum revenue that the company can make is for the point, (60, 40)
⇒ x = 60 treadmills
and y = 40 treadmills
Maximum Revenue = [tex]60 \times 750 + 40 \times 900 = 45000+36000 = \$81,000[/tex]
Therefore, the maximum revenue that the company can make from the treadmill sales is, $81,000
The cost of a car rental is thirty dollars a day plus fifteen cents a mile. If the total cost to rent the car was one hundred and eighty dollars, how many miles was the car driven if it was rented for four days?
Answer:
Step-by-step explanation:
Alright, lets get started.
Suppose car was driven x miles in its 4 days trip.
Cost of a car rental is thirty dollar per day.
So, for 4 days, the car rental will be = [tex]30*4=120[/tex] $
For 1 mile, it adds fifteen cents,
So, for x miles, the cost will be = [tex]0.15 x[/tex] $
As per question, total rent is 180 $
Total rent will be = [tex]120 + 0.15 x = 180[/tex]
Subtracting 120 in both sides
[tex]0.15 x = 180-120=60[/tex]
[tex]x=\frac{60}{0.15}[/tex]
[tex]x=400[/tex]
It means car was driven 400 miles. : Answer

A cyclist rode at an average speed of 15 mph for 30 miles. How long was the ride? Question 6 options: 0.5 hours 1 hour 2 hours 3 hours
Answer:
2 hours
Step-by-step explanation:
using the relationship
distance = speed × time, then
time = [tex]\frac{distance}{speed}[/tex] = [tex]\frac{30}{15}[/tex] = 2 hours
It will take 2 hours to cover 30 miles so option (C) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
A cyclist rode at an average speed of 15 mph for 30 miles.
So,
15 miles ⇒ hour
Multiply by 2
2 hours ⇒ 30 miles.
Hence "It will take 2 hours to cover 30 miles".

___ can be found by making x=0
Answer:
y intercept
Step-by-step explanation:
At first I didn't think there was enough information, but there is. In general terms, for any polynomial which is also a function, making x = 0 gives the point where (0,b) = the y intercept.
For example
using f(x) = x^2 + 4x + 6 when x = 0 the result left is f(0) = 6 so the y intercept is (0,6)
If you have x^2 + 6x the y intercept is (0,0)

Part A:
The range is the difference between the highest and lowest values:
Highest value = 78
Lowest value = 40
Range = 78-40 = 38
Part B:
The interquartile range is the difference between Q1 and Q3.
Q1 is the middle value of the lower half and Q3 is the middle value of the upper half.
There are 11 total numbers, 40 , 64, 66, 67,67,68,69,70, 71, 72, 78
The median would be the middle value, 68, so the lower half would be the 5 numbers below 68: 40 , 64, 66, 67,67.
The middle value of those numbers would be 66
The upper half are the 5 numbers above 68: 69,70, 71, 72, 78.
The middle value of those numbers is 71
The interquartile range would be 71 - 66 = 5
Part C:
The interquartile range is the better measure.
Mrs.Padre drives 2 hours at a n average speed of 35 miles per hour then she drives 3 hours at a speed of 48 miles per hour what is her average speed for the whole trip
She drove 2 hours at 35 miles per hour for a total of 35 * 2 = 70 miles.
She drove 3 hours at 48 miles per hour for a total of 48 * 3 = 144 miles.
Her total miles were: 70 + 144 = 214.
Her total driving time was 3 + 2 = 5 hours.
Divide her total miles by total time for her average speed:
214 / 5 = 42.8 miles per hour average speed.
Not sure if you need to round the answer or not.
Mrs. Padre's average speed for the entire trip is 42.8 miles per hour, which is calculated by dividing the total distance (214 miles) by the total time (5 hours).
To determine Mrs. Padre's average speed for the whole trip, we need to use the formula for average speed:
Average speed = Total distance / Total time
First, we calculate the distance traveled during each part of the trip:
For the first part: 2 hours * 35 miles/hour = 70 milesFor the second part: 3 hours * 48 miles/hour = 144 milesNext, we sum up the total distance and total time:
Total distance = 70 miles + 144 miles = 214 milesTotal time = 2 hours + 3 hours = 5 hoursNow we can calculate the average speed:
Average speed = 214 miles / 5 hours = 42.8 miles per hour

Use the Polygon tool to draw the image of the given quadrilateral under a dilation with a scale factor of 34 and center of dilation (0, 0) .
Answer:
See attached diagram
Step-by-step explanation:
Given quadrilateral has vertices at points A(-8,4), B(4,-4), C(0,-8) and D(-4,-4).
A dilation with a scale factor of [tex]\dfrac{3}{4}[/tex] and a center of dilation (0,0) has a rule
[tex](x,y)\mapsto \left(\dfrac{3}{4}x,\dfrac{3}{4}y\right).[/tex]
Then
A(-8,4)→E(-6,3);B(4,-4)→F(3,-3);C(0,-8)→G(0,-6);D(-4,-4)→H(-3,-3).See attached diagram for details.
Remark: If a scale factor is 34, then the rule is (x,y)→(34x,34y) and image vertices have coordinates (-272,136), (136,-136), (0,-272), (-136,-136).
If f(x)=2x+7 and g(x)=11x-4, find (f+g)x.
Answer:
(f+g)(x) = 13x + 3
Step-by-step explanation:
Rewrite f(x)=2x+7 and g(x)=11x-4 in columns, as follows:
f(x)=2x+7
+g(x)=11x-4
----------------
Now add each column separately.
f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")
2x + 11x = 13x, and, finally, 7-4 = 3.
Therefore,
f(x)=2x+7
+g(x)=11x-4
----------------
(f+g)(x) = 13x + 3

Step-by-step explanation:
Central angle = 8π/5 radians
Let's convert radians to degrees.
Answer:
The length of arc is 185.39 m
Step-by-step explanation:
Given that in a circle with a radius of 36.9 m, an arc is intercepted by a central angle of [tex]\frac{8\pi}{5}[/tex] radians.
we have to find the arc length.
[tex]Radius=36.9 m[/tex]
[tex]\text{Central angle=}\frac{8\pi}{5}[/tex]
The arc length can be calculated by the formula
[tex]L=r\theta[/tex]
[tex]\text{where r is radius and }\theta \text{ is central angle in radians. }[/tex]
[tex]L=36.9 \times \frac{8\pi}{5}[/tex]
[tex]L=36.9 \times \frac{8\times 3.14}{5}[/tex]
[tex]L=\frac{926.928}{5}=185.3856\sim 185.39 m[/tex]
hence, the length of arc is 185.39 m

What is your real rate of return is your savings account pays 2.5% interest and inflation is at 1%
Answer:
1.5
Step-by-step explanation:
The real rate of return is calculated as the difference between rate of interest and the inflation.
so,Interest=2.5%
Inflation=1%
=2.5-1
=1.5%
Answer:
1.485 % ( approx )
Step-by-step explanation:
We know that,
[tex]\text{Real rate of return}=\frac{1+\text{Nominal rate}}{1+\text{Inflation rate}}-1[/tex]
Given,
Nominal rate = 2.5 % = 0.025
Inflation rate = 1 % = 0.01,
[tex]\implies \text{Real rate of return}=\frac{1+0.025}{1+0.01}-1[/tex]
[tex]=\frac{1.025}{1.01}-1[/tex]
[tex]=1.01485149-1=0.01485149\approx 0.01485[/tex]
Thus, the real rate of return is 0.01485 or 1.485 %.

At the city museum, child admission is $6.10 and adult admission is $9.30 . On Sunday, four times as many adult tickets as child tickets were sold, for a total sales of $909.30 . How many child tickets were sold that day?
Answer:
21 child tickets
Step-by-step explanation:
For this problem, you'd use a system of equations.
First, define your variables.
x = # of child tickets sold
y = # of adult tickets sold
There were 4 times as many adult tickets (y) as child tickets (x) sold, so:
4 x = y
4 x - y = 0
93 (4 x - y = 0)
372 x - 93 y = 0
The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:
6.10 x + 9.30 y = 909.30
10 (6.10 x + 9.30 y = 909.30)
61 x + 93 y = 9093
372 x - 93 y = 0
433 x = 9093
433 x / 433 = 9093 / 433
