Please help with last 2 domain and range

Answers

Answer:

See below for answers and explanations

Step-by-step explanation:

Top left: Since y can't be greater than 0 but is equal to 0, then the range is (-∞,0] and the domain is (-∞,∞) since there are no domain restrictions

Top right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)

Bottom left: Since y cannot be less than 2 but equal to it, and x holds no domain restrictions, then the domain is (-∞,∞) and the range is [2,∞)

Bottom right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)

The power generated by an electrical circuit (in watts) as a function of its current ccc (in amperes) is modeled by: P(c)=-20(c-3)^2+180P(c)=−20(c−3) 2 +180

Answer:

The current that produces maximum power is 3A

Step-by-step explanation:

Given

[tex]P(c) = 20(c - 3)^2[/tex]

Required [Missing from the question]

The current that produces maximum power

First, we represent the function in standard form

[tex]P(c) = 20(c - 3)^2[/tex]

[tex]P(c) = 20(c - 3)(c - 3)[/tex]

Open bracket

[tex]P(c) = 20(c^2 -6c+ 9)[/tex]

[tex]P(c) = 20c^2 -120c+ 180[/tex]

The maximum value of c is:

[tex]Max(c) = \frac{-b}{2a}[/tex]

Where:

[tex]f(x) = ax^2 + b^2 + c[/tex]

By comparison: [tex]P(c) = 20c^2 -120c+ 180[/tex]

[tex]a = 20[/tex]

[tex]b = -120[/tex]

[tex]c = 180[/tex]

So, we have:

[tex]Max(c) = \frac{-b}{2a}[/tex]

[tex]Max(c) = \frac{-(-120)}{2 * 20}[/tex]

[tex]Max(c) = \frac{120}{40}[/tex]

[tex]Max(c) = 3[/tex]

Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 108 pi inches

Answers

Answer: [tex]9\pi\ in.[/tex]

Step-by-step explanation:

Given

The diameter of a circle is [tex]d=9\ in.[/tex]

So, the radius is [tex]r=\frac{d}{2}=4.5\ in.[/tex]

The circumference is given by [tex]2\pi r[/tex]

Insert the values

[tex]\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.[/tex]

Thus, the circumference of the circle is [tex]9\pi\ in.[/tex]

Answer:

396 mm squared

Step-by-step explanation:

(8 x 12) ÷ 2 = 48

48 x 2 = 96

10 x 10 = 100

100 x 3 = 300

Answer:

radius: 78 height: 92

im so sorry if im wrong! i did math and everything!

Assume the radius is 5 and the height is 4.

We first need to find the volume of both the TP roll and the volume of the closet.

In order to find the volume of the TP roll, we need to use the formula [tex]V[/tex] = [tex]\pi[/tex][tex]r^{2}[/tex][tex]h[/tex] (r meaning radius and h meaning height), so that means we have to do 3.14 × 5 × 5 × 4.

After solving, we get 314 as our answer.

Next we need to find the Volume of the closet by using the formula L × W × H (L meaning Length, W meaning Width, and H meaning height), so that means we have to do 36 × 108 × 36.

We then get 139,968 as our answer.

The last thing we need to do is 139,968 ÷ 314.

The answer we get is 445.

So the answer to this question is: About 445 rolls of TP can fit into the closet.

Karen is adding a border to a rectangular poster. The border will have a uniform width of X inches and run along all four sides, so Karen uses the functions land wto model the length and width, in inches, of her poster after she adds the border. l(x) = 2x+ 18 W(x) = 2x+ 24 Which function correctly represents the total area, in square inches, of Karen's poster, when a border x inches wide is included in the area?

A. A(X) = 4x + 432

B. A(X) = 4x2 + +42x + 432

C. A(x) = 4x2 + +84x + 432

D. A(x) = 4x + 432

Answers

Answer:

B. A(x) = 4x² + 42x + 432

Step-by-step explanation:

The area is the product of the width and the length:

A(x) = (2x + 18)(2x + 24) = 4x² + 42x + 432

Correct choice is B

Step-by-step explanation:

Divide it

The equivalent expression can be used to solve the quotient 2/3 divided by 4/5 is 5/6.

What is division?

Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.

The equivalent expression that can be used to solve the quotient 2/3 divided by 4/5 is;

[tex]= \dfrac{\dfrac{2}{3}}{\dfrac{4}{5}}\\\\=\dfrac{2}{3} \times \dfrac{5}{4}\\\\=\dfrac{1}{3} \times \dfrac{5}{2}\\\\=\dfrac{5}{6}[/tex]

Hence, the equivalent expression can be used to solve the quotient 2/3 divided by 4/5 is 5/6.

Essentially, it is sweetened water added to fruit puree that is churned and then frozen. It differs from regular ice cream and other frozen desserts because it contains no dairy, like cream or milk. As a result, sorbet has a very low fat content. With a low fat content, it means that sorbet needs to be served a little differently than regular ice cream. It needs to be stored at a lower temperature in order to scoop it into a cup or cone easily. If it is not stored at a lower temperature, it is frozen solid like an ice cube.The story of sorbet begins with the Roman Emperor, Nero, and his travels during the first century. The legend states that Nero established a line of runners from Italian cities to high up in the mountains. This allowed buckets of snow to travel from the mountains to his banquet hall whenever he pleased. Since fresh snow was so hard to get, only the richest families enjoyed the frozen dessert. Due to the lack of technology, fresh snow had to be retrieved from the mountains constantly if Nero wanted to eat the dessert. There was nowhere to keep it frozen so it would melt. Since Nero wanted a constant supply of the dessert, he needed a group of workers to keep fetching it from the mountains. Nero liked to flavor the fresh snow with honey and that's essentially what sorbet is, water and flavoring. This is the first record account of sorbet, which lead to other frozen desserts, like traditional ice cream.Select two details from the passage that support the main ideas that sorbet is different than ice cream, and sorbet dates back to Roman Emperor, Nero, in the first century.Group of answer choices"It differs from regular ice cream and other frozen desserts because it contains no dairy, like cream or milk." . . .
