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

[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]

Answer: |a|=−4

Step-by-step explanation:Divide each term in −|a|=4by −1 and simplify.

So the area of the shaded part of the rectangle is 125 square meters.

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

= 160 m² - 35 m²

= 125 m²

The area of the model on the right is 6.25 square centimeters.

What is area ?

Area is a measurement of the size of a two-dimensional surface or region. It is the amount of space inside a closed figure or shape, and is typically measured in square units such as square meters, square feet, or square centimeters.

Since the two models represent the same rectangular patio, they must have the same area.

Let A be the area of the model on the right in square centimeters.

Using the ratios given in the problem, we can write:

A/4 = (1.25 ft/1 cm)²

Simplifying the right-hand side, we get:

A/4 = 1.5625 ft²/cm²

Multiplying both sides by 4, we get:

A = 6.25 ft²

Therefore, the area of the model on the right is 6.25 square centimeters.

The probability is approximately 0.129 or 12.9%.

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%.

Answer: Let's call the portions that the second friend gets "x". Then, the third friend gets four times that amount, which is 4x. Finally, the first friend gets four times the third friend's portion, which is 4(4x) = 16x.

The sum of the portions is equal to the total prize money of $273,000, so:

x + 4x + 16x = 273000

21x = 273000

x = 13000

So, the second friend gets $13,000, the third friend gets four times that amount, which is $52,000, and the first friend gets four times the third friend's portion, which is $208,000.

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.

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°
