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]

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.

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 (-∞,∞)

Answer:

The answer is: y= -5x-2

Step-by-step explanation:

Angle M = Angle R

47x - 17 = 32x + 28

15x = 45

x = 3

Angle M = 47(3) - 17 = 124°

Angle R = Angle M = 124°

Angle Q = 180 - Angle M = 56°

Angle N = Angle Q = 56°

Answer:

Braylee’s music is 3 times louder than Jessica's

Step-by-step explanation:

Given

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]I_0 = 10^{-12}[/tex]

Required

Number of times Braylee's music is louder than Jessica's

First, we calculate the loudness of Jessica's music.

From the question;

[tex]I = 10^{-9}[/tex]

So, we have:

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]L = 10\log\frac{10^{-9}}{10^{-12}}[/tex]

Apply law of indices

[tex]L = 10\log{10^{12-9}}[/tex]

[tex]L = 10\log{10^3[/tex]

Apply law of logarithm

[tex]L = 3*10\log{10[/tex]

[tex]\log10 = 1[/tex]

So:

[tex]L_1 = 3*10*1 = 30[/tex]

First, we calculate the loudness of Braylee's music.

From the question;

[tex]I = 10^{-3}[/tex]

So, we have:

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]L = 10\log\frac{10^{-3}}{10^{-12}}[/tex]

Apply law of indices

[tex]L = 10\log{10^{12-3}}[/tex]

[tex]L = 10\log{10^9[/tex]

Apply law of logarithm

[tex]L = 9*10\log{10[/tex]

[tex]L_2 = 9*10*1 = 90[/tex]

At this point, we have:

[tex]L_1 = 30[/tex] --- Jessica's

[tex]L_2 = 90[/tex] --- Braylee's

Divide L2 by L1 to get the required number of times

[tex]n = \frac{L_2}{L_1}[/tex]

[tex]n = \frac{90}{30}[/tex]

[tex]n = 3[/tex]

Answer:

5/6

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.

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.
