The answer is that the Rental agency will earn a maximum income of 25200 dollars when it charges 60 dollars per day.
What is Income?We can Define Income as it is the money that an individual or organization receives in return for their services or goods.
Given,
440 cars at a rate of 40 dollars per day
Each 1dollar increase in rate and 10 fewer cars rented.
Rental:
R(x) = ( 40 + x ) dollars per car per day
A number of cars rented :
N(x) = 440 - 10 x
Income:
[tex]I = (40+x)(440-10x)[/tex]
For maximum Income,
[tex]\frac{dI}{dx} = 0[/tex]
Then,
[tex]\frac{dI}{dx} = \frac{d}{dx} [(40+x)(440-10x)][/tex]
Using formula
[tex]\frac{d}{dx} (u,v)=u \frac{d}{dx}v+v \frac{d}{dx}u[/tex]
Then,
[tex]\frac{d}{dx} [(40+x)(440-10x)]=(40+x) \frac{d}{dx}(440-10x)+(440-10x)\frac{d}{dx}(40+x)[/tex]
[tex](40+x)(-10) + (440-10x)(1) = 0[/tex]
[tex]-400 -10x + 440 - 10x = 0[/tex]
[tex]40 - 20x = 0[/tex]
[tex]20x = 40[/tex]
[tex]x=\frac{40}{20}[/tex]
[tex]x = 20[/tex]
Rental :
[tex](40 +x) = (40+20) = \$\ 60[/tex]
And maximum income:
[tex]= (40+x)(440-x)[/tex]
[tex]= (40+20)(440-20)[/tex]
[tex]= 60 * 420[/tex]
[tex]= \$\ 25200[/tex]

Sequence having rule f(n) = n² - 5, the first four terms will be -4, -1, 4, and 11.
What is a sequence?A sequence in mathematics is a group of integers that adhere to a specific pattern or rule. A sequence of numbers might be infinite or finite, and they are arranged in a certain order.
Every number in the sequence is referred to as a term, and its location within the sequence is referred to as its index. As an illustration, the first term in the series 1, 3, 5, 7, 9, is 1, the second term is 3, the third term is 5, and so on.
Now,
The explicit rule for the sequence is given by f(n) = n² - 5, which means that to find the nth term of the sequence, we need to plug in the value of n into this formula.
To find the first four terms of the sequence, we can simply substitute n = 1, 2, 3, and 4, respectively, into the formula and evaluate the expression.
The first term is f(1) = 1² - 5 = -4.
The second term is f(2) = 2² - 5 = -1.
The third term is f(3) = 3² - 5 = 4.
The fourth term is f(4) = 4² - 5 = 11.
Therefore,
the first four terms of the sequence defined by the explicit rule f(n) = n² - 5 are -4, -1, 4, and 11.

Therefore , the solution of the given problem of volume comes out to be chocolate bar therefore has a 2940 cubic centimetre (cm3) capacity.
Describe volume.The volume of a three-dimensional item, which is measured in cubic units, describes how much room it occupies. Two instances of cubic units are the numbers cm3 as well as in3. But mass can be used to measure an object's dimensions. Typically, an object's weight is transformed into mass units like kilos or kilogrammes.
Here,
The length, breadth, and height of the rectangular, prism-shaped chocolate bar can be multiplied to determine its volume.
Size = 15 centimetres
Width = undefined
Size equals 2 centimetres (thickness)
To solve for the width, we can rearrange this algorithm as follows:
=> Area/Length = Width
We are aware that the necessary length is 15 centimetres and the necessary area is 1470 cm2, so:
=> width = 1470/15
=> 98 centimetres.
Now that we are aware of every aspect of the chocolate bar, we can calculate its volume:
=> Volume = Length * Width * Height
=> 15 cm x 98 cm x 2 cm = 2940 cm³
The chocolate bar therefore has a 2940 cubic centimetre (cm3) capacity.

So the area of the shaded part of the rectangle is 125 square meters.
What is area?Area is the measure of the size of a two-dimensional surface or region. It is typically measured in square units, such as square meters or square feet. The area of a shape is the amount of space that it occupies within a defined boundary. The formula for the area of a shape varies depending on the shape, but for common shapes like rectangles, triangles, and circles, there are specific formulas that can be used to calculate the area. Knowing the area of a shape is important for many practical purposes, such as calculating the amount of paint needed to cover a wall or the amount of carpet needed to cover a floor.
Here,
To find the area of the shaded part of the rectangle, we need to subtract the area of the unshaded triangle from the total area of the rectangle. The rectangle has a length of 16 meters and a width of 10 meters, so its total area is:
Area of rectangle = length x width
= 16 m x 10 m
= 160 m²
The unshaded triangle has a base of 9 meters and a height of 10 meters, so its area is:
Area of triangle = 1/2 x base x height
= 1/2 x 7 m x 10 m
= 35 m²
Therefore, the area of the shaded part of the rectangle is:
Area of shaded part = Area of rectangle - Area of triangle

What is midsegment of a triangle?The midsegment of a triangle is a line segment that connects the midpoints of two sides of a triangle. More specifically, if a triangle has sides of lengths a, b, and c, then the midsegment connects the midpoints of the two sides of length a and is parallel to the side of length c.
The length of the midsegment is half the length of the third side (c/2).
In other words, if a triangle has sides AB, BC, and AC, then the midsegment connects the midpoint of AB (denoted as M) to the midpoint of BC (denoted as N) and is parallel to AC. The length of the midsegment MN is equal to half the length of AC (MN = 1/2 * AC).

Calculate the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag.
The probability is approximately 0.129 or 12.9%.
Describe probability ?Probability can also be used to describe more complex events, such as the likelihood of a stock price increasing by a certain amount in a given period of time, or the probability of a medical treatment being effective for a certain disease.
To calculate the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag, we need to use the binomial probability formula:
P(X >= 48) = 1 - P(X < 48)
Where
X is the number of orange Stattles in a 14 ounce bag
P(X < 48) is the probability of getting less than 48 orange Stattles in a 14 ounce bag
To calculate P(X < 48), we need to use the binomial probability formula:
[tex]P(X = x) = (nCx) * p^x * q^{(n-x)[/tex]
Where
n is the number of Stattles in a 14 ounce bag (we don't know this value)
x is the number of orange Stattles in a 14 ounce bag (we want to find the probability of getting less than 48)
p is the probability of getting an orange Stattle (0.4)
q is the probability of getting a non-orange Stattle (0.6)
nCx is the binomial coefficient
nCx is the binomial coefficient, which can be calculated using the formula:
nCx = n! / (x! * (n-x)!)
where ! denotes the factorial function.
We can use a cumulative binomial distribution table or a binomial calculator to find the probability of getting less than 48 orange Stattles in a 14 ounce bag. For example, using an online calculator, we find that:
P(X < 48) = 0.871
Therefore, the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag is:
P(X >= 48) = 1 - P(X < 48) = 1 - 0.871 = 0.129
So, the probability is approximately 0.129 or 12.9%.

Which function does not have a period of 2 pie?
Answer:
Step-by-step explanation:
The trigonometric function that does not have a period of 2π is the tangent function, denoted by tan(x).
The period of a trigonometric function is the length of one complete cycle of the function. For the sine and cosine functions, the period is always 2π, which means that the function repeats itself every 2π units.
However, the tangent function has a period of π, which means that it repeats itself every π units. This is because the tangent function has vertical asymptotes at x = (n + 1/2)π, where n is an integer, and the function changes sign between these asymptotes. Therefore, the tangent function does not have a period of 2π.
Use the Simple Interest formula to find the simple interest. (l=prt)
What is the equation of the line containing points (3,1),(9,3)
slope = 3-1/9-3 = 2/6 = 1/3
y = 1/3x + b
1 = 1/3(3) + b
1 = 1 + b
b = 0
equation: y = -1/3x + 0
This is the slope-intercept form for the equation of a line with slope m and y-intercept b.
y=mx+b
This is a formula for the slope of a line that passes through the points (x1,y1) and (x2,y2).

4
= b Subtract 2 from both sides of the equation
The slope is 2, and the y-intercept is 4. Write the equation of the line in slope-intercept form.
y
= mx+b
y
= 2x+4
So the y-intercept is 4 the equation of the line in slope-intercept form is:
y = 2x + 4
What is in slope-intercept form?When the line to be examined's slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).
According to the given information:y = mx + b
m = (y2 - y1) / (x2 - x1)
Using the points (-4, -4) and (1, 6), we can find the slope of the line passing through them:
m = (6 - (-4)) / (1 - (-4)) = 10 / 5 = 2
So the slope of the line is 2. Let's use the point (1, 6):
y = mx + b
6 = 2(1) + b (substitute m = 2, x = 1)
6 = 2 + b
b = 6 - 2 = 4
So the y-intercept is 4 the equation of the line in slope-intercept form is:
y = 2x + 4

If the sum of the measures of the three angles shown is 163
, what is the measure of
Answer:
See below.
Step-by-step explanation:
We are asked to find the measure of ∠CEB.
We already know that the 3 angles combined have a total sum of 163°.
Let's set the 3 angles equal to 163°.
[tex]x-10+4x +2x+5=163[/tex]
Now, we should Combine Like Terms.
What is Combining Like Terms?
Combining Like Terms is adding, or subtracting together 2 or more numbers or variables that are alike.
For example, if we were given the expression;
[tex]5x + 3 - 2x + 9[/tex]
We should combine 5x and 2x, 3 and 9 since they are like terms.
For our equation;
[tex]x-10+4x +2x+5=163[/tex]
We should combine x, 4x, and 2x. We also should combine -10, 5, and 163.
Afterwards, we should have:
[tex]7x=168[/tex]
Simplify:
[tex]x= 24[/tex]
Substitute 24 within the value of x in the given expression for ∠CEB.
Substitute:
[tex]-10 + 4(24) = 86[/tex]
The measure of ∠CEB = 86°
the cost of four popcorns (p) and twenty dollars worth of movie tickets
A statement with more than two variables or numbers can be written as an expression using addition, subtraction, multiplication, and division operations. Tickets for the film are $16 each.
What is an expression?A combination of symbols and/or numbers that infers a quantity or a mathematical relationship between two quantities is known as an expression in mathematics. Variables, constants, and operators like addition, subtraction, multiplication, and division can all be found in expressions.
Given that,
Total amount spent = $24.
Cost of the movie ticket = m
Cost of popcorn and soft drinks = 1/2 x m = $(m/2)
The cost of the movie will be calculated as,
Cost of popcorn + Cost of soft drinks + Cost of the movie = $24
[tex]\dfrac{m}{2} + m = 24[/tex]
[tex]\dfrac{(m + 2m)} { 2} = 24[/tex]
[tex]\dfrac{3m}{2} = 24[/tex]
3m = 24 x 2
m = 8 x 2
m = $16
The cost of the movie ticket is $16.
