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:

x = 11.2

Step-by-step explanation:

hypotenuse = 8.4 (radius) + 5.6 = 14  

using the Pythagorean theorem:

x² = 14² - 8.4² = 196 - 70.56 =125.44

x = √125.44 = 11.2

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]

The statements that are necessary and sufficient to prove that ABCD is a parallelogram are, (B), (C) and (D).

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

From the properties of parallelograms the statements that are necessary and sufficient to prove that ABCD is a parallelogram are,

[tex]\overline{AE}[/tex] ≅ [tex]\overline{CE}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{DE}[/tex]  as diagonal of a parallelogram bisect each other.

[tex]\overline{AB}[/tex] ≅ [tex]\overline{CD}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{CE}[/tex] opposite sides of a parallelogram are equal.

m∠ABC + m∠BAD is 180° as the sum of the adjacent sides in a parallelogram are supplementary.

Answer:

B is your answer

Step-by-step explanation:

Hope it is right.

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.

The graph of inequality that represents the scenario is graph (b)

The given parameters are:

People signed up = 4

People needed = At least 9

Represent the number of people who are still needed with x.

So, we have the following inequality expression

[tex]x + 4 \ge 9[/tex]

Subtract 4 from both sides

[tex]x \ge 5[/tex]

The above means that, 5 or more people are still needed

The graph of inequality that represents [tex]x \ge 5[/tex] is graph (b)

Third option: Rocks being broken apart

Step-by-step explanation:

Have a good day :)

Answer: rock being broken apart

Step-by-step explanation:

Answer:

50°

Step-by-step explanation:

Let :

Let the angle = x

Second angle = x + 10

Third angle = x - 10

Sum of angles in a triangle = 180

x + (x + 10) + (x - 10) = 180

x + x + 10 + x - 10 = 180

3x = 180

x = 180 / 3

x = 60

Smallest angle :

x - 10 = 60 - 10 = 50°
