The answer is that the Rental agency will earn a maximum income of 25200 dollars when it charges 60 dollars per day.

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

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]

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.

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°

Answer:

Coordinates of center: (0, 5)

Radius of circle: 3

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.

Therefore , the solution of the given problem of volume comes out to be  chocolate bar therefore has a 2940 cubic centimetre (cm3) capacity.

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 y-intercept is 4 the equation of the line in slope-intercept form is:

y = 2x + 4

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).

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

To create a percent bar graph for the cards in the deck, we first need to determine the percentage of each type of card in the deck.

There are a total of 25 cards in the deck, and the breakdown of each type of card is as follows:

4 cards labeled with a "": (4/25) x 100% = 16%

6 cards labeled with a "": (6/25) x 100% = 24%

10 cards labeled with a "": (10/25) x 100% = 40%

5 cards labeled with a "": (5/25) x 100% = 20%

Now that we have the percentage for each type of card, we can create the percent bar graph.

Cards Label    

"" 16%

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,

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

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
