Answer:
In order to maximize profit, each widget should sell for $26.70.
Step-by-step explanation:
The total amount of profit y given by the selling price of each widget x is given by:
[tex]y=-15x^2+801x-5900[/tex]
And we want to determine the price of each widget such that is yields the maximum profit.
Since the equation is a quadratic, the maximum profit will occur at the vertex of our parabola.
The vertex of a quadratic is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(-\frac{b}{2a}\right)\right)[/tex]
So, let's find the vertex. In our equation, a = -15, b = 801, and c = -5900.
Therefore, the price that maximizes profit is:
[tex]\displaystyle x=-\frac{801}{2(-15)}=\$26.70[/tex]
Therefore, in order to maximize profit, each widget should sell for $26.70.
Notes:
Then substituting this back into the equation, the maximum profit is:
[tex]y_{\text{max}}=-15(26.7)^2+801(26.7)-5900=\$ 4793.35[/tex]

Working alone, it takes Kristin 11 hours to harvest a field. Kayla can harvest the same field in 16 hours. Find how long it would take them if they worked together.
Answer:
(11 hrs + 16 hrs)/2 = 13.5 hrs
13.5 hrs /2 = 6.75 hrs
Kevin takes classes at both Westside college and Pinewood college at Westside class fees are $98 per credit hour and Pinewood they are $115 per credit hour. Karen is taking combined total of 18 credit hours at the two schools. Suppose that she's taking W credit hours at Westside. Write an expression for the combined total dollar amount that she paid for the class fees
Answer:
y = 98(w) + 115(18 - w)
Step-by-step explanation:
The expression that represents how much Kevin spends for classes at both schools : (#credits at Westside)($98) + (#credits at pinewood)($115). If he takes all credits at Westside this is 18(98) + 0, which would be the lowest cost it could be, if he takes all credits at Pinewood this would be 0 + (18)(115) which would be the maximum Bob could pay for 18 credits. If y is the total cost of is courses, then y = 98(w) + 115(18 - w). Using the distributive property, this can be simplified.

Which similarity statement and justification correctly identifies the triangles'
relationship? *
Help plz
Answer:
(c) [tex]\triangle ABC[/tex] to [tex]\triangle EDC[/tex] by AA
Step-by-step explanation:
Given
See attachment for triangles
Required
The relationship between both triangles
First, we determine the corresponding sides.
The corresponding sides will be determined based on the length of each side (i.e. bigger sides correspond while smaller sides correspond).
So, we have:
[tex]AC\ to\ EC[/tex]
[tex]BC\ to\ DC[/tex]
Next, is to name the triangle base on the corresponding sides
The names will be: [tex]\triangle ABC[/tex] and [tex]\triangle EDC[/tex]
Lastly, is to check the scale ratio (k).
For both triangles to correspond, the scale ratio must be the same
So:
[tex]k = \frac{EC}{AC} = \frac{DC}{BC}[/tex]
[tex]k = \frac{8}{6} = \frac{12}{9}[/tex]
[tex]k = \frac{4}{3} = \frac{4}{3}[/tex]
[tex]k = \frac{4}{3}[/tex]
Hence, the theorem is: [tex]\triangle ABC[/tex] to [tex]\triangle EDC[/tex] by AA

use the area of the rectangle to find the area of the triangle
Answer:
The area of the Triangle is 1/2 the area of the Rectangle
The answer is D.
Step-by-step explanation:
Ignore the area of the rectangle for the moment, just so you can get the answer.
Area Triangle = 1/2 * b * h
Area Triangle = 1/2 * 8 * 4
Area Triangle = 1/2 32
Area Triangle = 16 square feet.
The area of the rectangle = L * W
L = 8
W = 4
Area of the rectangle = 8*4 = 32
What expression is undefined
Answer:
Step-by-step explanation:How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero. We can't divide by zero in math, so we end up with an expression that we can't solve.
To find:
Which of the four expressions are undefined, or not possible to calculate.
Steps:
Lets go through each option one by one
Option A:
[tex]-\frac{0}{2}[/tex] , in this expression a negative zero is divided by 2, we know that zero divided by any number is equal to 0.
[tex]-\frac{0}{2}= -0 = 0[/tex]
Since option A is defined. Now lets go to option B
Option B:
[tex]\frac{3}{6-6}= \frac{3}{0}[/tex]
this expression shows 3 divided by a zero, but dividing any non-zero number by 0 is not possible.
Therefore option B is undefined. We found out the answer but lets continue for learning purposes.
Option C:
0 ÷ 11 = [tex]\frac{0}{11}[/tex]
This expression is similar to the first expression, where zero is divided by any number.
[tex]\frac{0}{11} = 0[/tex]
Therefore option C is defined. Now let continue to option D
Option D:
[tex]\frac{-4+0}{8}= \frac{-4}{8}= \frac{-1}{2}[/tex]
In this expression, the final answer after simplifying is -1/2 which is a number and is possible to calculate
Therefore option D is defined.

The amount of flight time between failures of an airplane engine is exponentially distributed with mean 900 hours. If the engine is inspected every 600 hours of flight time, what is the probability that the engine will fail before it is inspected
Answer:
0.4866 = 48.66% probability that the engine will fail before it is inspected
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
Exponentially distributed with mean 900 hours.
This means that [tex]m = 900, \mu = \frac{1}{900}[/tex]
If the engine is inspected every 600 hours of flight time, what is the probability that the engine will fail before it is inspected?
This is [tex]P(X \leq 600)[/tex], which is:
[tex]P(X \leq 600) = 1 - e^{-\frac{600}{900}} = 0.4866[/tex]
0.4866 = 48.66% probability that the engine will fail before it is inspected

In 2000, the population of a district was 32,600. With a continuous annual growth rate of approximately 2%, what will the
population be in 2010 according to the exponential growth function?
Round the answer to the nearest whole number
Answer:
39,739
Step-by-step explanation:
The formula for exponential growth regarding this situation would be y=32600(1+0.02)^10, because 32600 is our initial amount, 1.02 is our growth rate, and 10 is the number of years. after putting it into a calculator you get 39.739.

The value of (cosx-sinx)/(cosx+sinx) is 1/7 if the x is an acute angle, and tan x=3/4
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
tanx = 3/4 (x is an acute angle)
[tex]\rm \dfrac{sinx}{cosx}=\dfrac{3}{4} \\\\\ \rm \dfrac{cosx}{sinx}-1=\dfrac{4}{3}-1\\\\\rm \dfrac{cosx-sinx}{sinx}=\dfrac{1}{3}\\\\[/tex] ….(1)
[tex]\rm \dfrac{sinx}{cosx}=\dfrac{3}{4} \\\\\ \rm \dfrac{cosx}{sinx}+1=\dfrac{4}{3}+1\\\\\rm \dfrac{cosx+sinx}{sinx}=\dfrac{7}{3}\\\\[/tex] …(2)
Divide (1) ÷ (2)
(cosx-sinx)/(cosx+sinx) = (1/3)/(7/3) = 1/7
Thus, the value of (cosx-sinx)/(cosx+sinx) is 1/7 if the x is an acute angle, and tan x=3/4

Answer:
slope = 3/4
Step-by-step explanation:
(=^w^=)
can do 7-4/-5--9
3/4 woof
The slope of the line represented by the given data points is 3/4.
To find the slope of the line represented by the given data points, we can use the formula for slope:
slope = (change in y) / (change in x)
Let's calculate the changes in y and x using the given data points:
Change in y:
From y = 4 to y = 16, there is an increase of 16 - 4 = 12.
Change in x:
From x = -9 to x = 7, there is an increase of 7 - (-9) = 16.
Now, we can calculate the slope using the formula:
slope = (change in y) / (change in x)
= 12 / 16
= 3 / 4
Therefore, the slope of the line represented by the given data points is 3/4.

Given that the quadrilateral shown is a rhombus, which statements are correct? A) mz1 = 32° D) m26 = 58° B) m 2 = 58° E) m27 = 32° C) mz3 = 32°
Angle 4 would equal the given angle in the opposite corner so angle 4 = 32 degrees.
The diagonal line is a bisector so angle 3 = the given angle of 32 and then angle 5 would also be 32 degrees.
The two diagonals are perpendicular so angle 8 would be 90 degrees.
The three inside angles of a triangle need to equal 180 so angle 1 would be 180-90-32 = 58 and angle 2 would also be 58.
Here are all the angles:
1 = 58
2 = 58
3 = 32
4 = 32
5 = 32
6 = 58
7 = 58
8 = 90
