Find the maximum revenue for the revenue function R(x) = 395x − 0.9x2
The maximum revenue obtained for the given revenue function is 43340.
What is termed as maxima and maximum value?Maxima and minima are the highest and lowest values of a function within a given set of ranges.
The maximum value of the function under the entire range is known as the absolute maxima, and the minimum value is recognized as the absolute minima.Range refers to the difference between both the maximum and minimum values of observations in a data set.Now, as per the given question;
The given revenue function is; R(x) = 395x − 0.9x²
Differentiate the given function with respect to x.
dR/dx = 395 − 2×0.9x
dR/dx = 395 - 1.8x
Put the given equation equal to zero and find the critical point for which the function will become maximum.
395 - 1.8x = 0
x = 219.44
x ≈≈ 220.
Substitute the obtained value of x in the revenue function to find its maximum value.
R(x) = 395x − 0.9x²
R(220) = 395×220 − 0.9(220)²
R(220) = 86900 - 43560
R(220) = 43340.
Therefore, the maximum revenue calculated for the given revenue function is 43340.

Answer:
[tex]z - 0.05z = 236.60[/tex]
Step-by-step explanation:
Given
[tex]Discount = 5\%[/tex]
[tex]Total\ Cost = 236.60[/tex]
Represent the cost of goods bought with z
When the coupon is applied, the discount becomes
[tex]Discount = 5\% * z[/tex]
This gives:
[tex]Discount = 0.05 * z[/tex]
[tex]Discount = 0.05z[/tex]
The discount subtracted from the cost of good will gives the total amount paid.
So, we have:
[tex]Cost\ of\ Goods - Discount = Total\ Cost[/tex]
This gives:
[tex]z - 0.05z = 236.60[/tex]
Hence, option (a) is correct
Two parallel lines are cut by a transversal. What is the measure of angle6 ?
Answer:
A
Step-by-step explanation:
Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.
The measure of angle 6 is 57°
The correct answer is an option (A)
What are parallel lines?"The lines in the same plane that are at equal distance from each other and never meet."
What is transversal?"A line that passes through two lines in the same plane at two distinct points in the geometry. "
What are opposite angles?"The angles directly opposite to each other when two lines intersect in a plane."
For given question,
Line n and line p are parallel lines and line t is the transversal.
Here, angle 1 and angle 4 are opposite angles.
⇒ ∠1 = ∠4
We have been given that ∠1 = 123°
⇒ ∠4 = 123°
Also, angle 4 and angle 6 are interior angles on the same side of the transversal.
We know that each pair of interior angles on the same side of the transversal is supplementary.
⇒ ∠4 + ∠6 = 180°
⇒ 123° + ∠6 = 180°
⇒ ∠6 = 180° - 123°
⇒ ∠6 = 57°
Therefore, the measure of angle 6 is 57°
The correct answer is an option (A)

A man has mislaid his wallet. He thinks there is a 0.4 chance that the wallet is somewhere in his bedroom, a 0.1 chance it is in the kitchen, a 0.2 chance it is in the bathroom, and a 0.15 chance it is in the living room. What is the probability that the wallet is a) somewhere else? b) in either the bedroom or the kitchen?
Answer:
a. Probability = 0.15
b. Probability = 0.3
Step-by-step explanation:
Given
[tex]P(Bedroom) = 0.4[/tex]
[tex]P(Kitchen) = 0.1[/tex]
[tex]P(Bathroom) = 0.2[/tex]
[tex]P(Living\ room) = 0.15[/tex]
Solving (a): Probability of being somewhere else
This is calculated by subtracting the sum of given probabilities from 1.
[tex]Probability = 1 - (0.4 + 0.1 + 0.2 + 0.15)[/tex]
[tex]Probability = 1 - 0.85[/tex]
[tex]Probability = 0.15[/tex]
Solving (b): Probability of being in bedroom or kitchen
This is calculated as:
[tex]Probability = P(Bedroom) + P(Kitchen)[/tex]
[tex]Probability = 0.2 + 0.1[/tex]
[tex]Probability = 0.3[/tex]

On his first three tests, Trevor scored 86, 83, and 78. What score must he get on his fourth test to have an average (mean) of 80 for all four tests?
Answer:
Trevor must score a 73.
Set UpWe will create an equation that has four values (three knowns, one unknown) that will divide by 4 to find the average.
Our equation will look like this:
[tex]\displaystyle \frac{86+83+78+x}{4}=80[/tex]
SolveFirst, combine all like terms.
[tex]\displaystyle \frac{247+x}{4}=80[/tex]
Then, divide the fraction.
[tex]\displaystyle \frac{247}{4} + \frac{x}{4} = 80[/tex]
Subtract 247/4 from both sides of the equation.
[tex]\displaystyle \frac{247}{4} - \frac{247}{4} + \frac{x}{4} = 80 - \frac{247}{4}[/tex]
[tex]\displaystyle \frac{x}{4} = \frac{73}{4}[/tex]
Then, multiply both sides of the equation by 4 to get rid of the denominator and isolate the variable.
[tex]4\times\displaystyle \frac{x}{4} = 4\times\frac{73}{4}[/tex]
[tex]x=73[/tex]

711.6Y/
K²
for K².
The answer is K^2 = 711.6Y on solving the given equation.
Given that, 1 = 711.6Y/K^2 and we have to solve it for the value of K^2. For this we simply have to solve the given equation steps wise. So, let's proceed to solve the equation.
1 = 711.6Y/K^2
Now, multiply K^2 with 1, we get
K^2 = 711.6Y
So, the value of k^2 will be equal to Y times 711.6 and further we can solve it for the various value of Y.
Let us suppose, we have to solve the above equation for the specific value of Y.
So, put Y = 1
On solving, we get
K^2 = 711.6x1
K^2 = 711.6
K = (711.6)^(1/2)
K = 26.67
∴ K^2 = 711.6Y is the equation we will get on solving the equation given to us in the question.
Hence, K^2 = 711.6Y is the required answer.

Find the following.

Х
(q or)(-1) = 0

?
Answer:
(r o q)(-1) = 20
(q o r)(-1) = -11
Step-by-step explanation:
Given
[tex]q(x) = -2x + 1[/tex]
[tex]r(x) = 2x^2 + 2[/tex]
Solving (a): (r o q)(-1)
In function:
(r o q)(x) = r(q(x))
So, first we calculate q(-1)
[tex]q(x) = -2x + 1[/tex]
[tex]q(-1) = -2(-1) + 1[/tex]
[tex]q(-1) = 2 + 1[/tex]
[tex]q(-1) = 3[/tex]
Next, we calculate r(q(-1))
Substitute 3 for q(-1)in r(q(-1))
r(q(-1)) = r(3)
This gives:
[tex]r(x) = 2x^2 + 2[/tex]
[tex]r(3) = 2(3)^2 + 2[/tex]
[tex]r(-1) = 2*9 + 2[/tex]
[tex]r(-1) = 20[/tex]
Hence:
(r o q)(-1) = 20
Solving (b): (q o r)(-1)
So, first we calculate r(-1)
[tex]r(x) = 2x^2 + 2[/tex]
[tex]r(-1) = 2(-1)^2 + 2[/tex]
[tex]r(-1) = 2*1 + 2[/tex]
[tex]r(-1) = 6\\[/tex]
Next, we calculate r(q(-1))
Substitute 6 for r(-1)in q(r(-1))
q(r(-1)) = q(6)
[tex]q(x) = -2x + 1[/tex]
[tex]q(6) = -2(6) + 1[/tex]
[tex]q(6) =- 12 + 1[/tex]
[tex]q(6) = -11[/tex]
Hence:
(q o r)(-1) = -11
What is an equation of the line that passes through the point ( 6 , − 2 ) (6,−2) and is perpendicular to the line 6 x + y = 2 6x+y=2?
Answer:
An equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:
[tex]y=\frac{1}{6}x-3[/tex]Step-by-step explanation:
We know that the slope-intercept form of the line equation is
y=mx+b
where m is the slope and b is the y-intercept.
Given the line
6x+y=2
Simplifying the equation to write into the slope-intercept form
y = -6x+2
So, the slope = -6
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be: -1/-6 = 1/6
Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 1/6 and the point (6, -2)
[tex]y-\left(-2\right)=\frac{1}{6}\left(x-6\right)[/tex]
[tex]y+2=\frac{1}{6}\left(x-6\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=\frac{1}{6}\left(x-6\right)-2[/tex]
[tex]y=\frac{1}{6}x-3[/tex]
Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:
[tex]y=\frac{1}{6}x-3[/tex]
