The intensity of soundwave at a distance of 12 miles is 222.22 miles.

The link between two variables whose ratio is equal to a constant number is known as a direct proportional, while the multiplication of two variables whose ratio is equal to a constant number is known as an inversely proportional.

It is given that the intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. therefore, the relation between the intensity of the radio wave(I) and distance(r) can be written as,

[tex]I\propto \dfrac{1}{r^2}\\\\\\I=k \dfrac{1}{r^2}[/tex]

Now, it is stated that the intensity of the radio wave at a distance of 2 miles is 8000 units, therefore, substituting the value in the above equation to get the value of the constant,

[tex]I=k\dfrac{1}{r^2}\\\\8000=k\dfrac{1}{2^2}\\\\8000=k\dfrac{1}{4}\\\\k = 8000 \times 4 = 32,000\rm\ units[/tex]

Thus, the value of the constant k is 32,000 units, and the equation of the intensity of the radio signal can be written as,

[tex]I=\dfrac{32,000 }{r^2}[/tex]

Further, the intensity of soundwave at a distance of 12 miles will be equal to,

[tex]I=\dfrac{32,000 }{r^2}\\\\I=\dfrac{32,000 }{12^2}\\\\I=\dfrac{32,000 }{144}\\\\I = 222.22\rm\ units[/tex]

Hence, the intensity of soundwave at a distance of 12 miles is 222.22 miles.

With the Hubble's constant H₀, the estimated age of the universe would be:

T = 8,332,452,617.49 years.

We know that the age of the universe is something near to the time the galaxies needed to reach their current distance:

T = D/V

And by Hubble's law, we know that:

V = H₀*D

Then we can write:

T = D/(H₀*D) = 1/H₀

So, we can say that the age of the universe is something near the inverse of Hubble's constant.

Then we have:

T = 1/(36 km/s*Mly) = (1/36)  s*Mly/km

Now we need to perform the correspondent change of units.

1 Mly = 1 million light-years

Such that:

1 ly = 9.461*10^12 km

Then 1 million light-years over km is equal to:

1 Mly/km = 1,000,000*(9.461*10^12 km)/km = 9.461*10^18

Then we can replace it:

T = (1/36) s*Mly/km = (1/36)*9.461*10^18 s

T = 2.628*10^17 s

This is the age in seconds, but we want it in years.

We know that:

1 year = 3.154*10^7 s

Then to change the units, we compute:

T = (2.628*10^17 s/3.154*10^7 s)* 1 yea

T = 8,332,452,617.49 years.

The main advantage with boxplots (aka box and whisker plots) is that we can spot the five number summary very quickly. The five number summary consists of these items:

The min and max are the left-most and right-most tips of the whiskers, assuming there aren't any outliers. They are the smallest and largest items.

The left and right edges of the box represent Q1 and Q3 in that order. The vertical line inside the box is the median. The vertical line does not have to be at the exact center of the box.

Answer:

C. 112 cubic inches

Step-by-step explanation:

Two solve this weird-looking house problem, first let's see what it is made of.

Split the area into two volumes.

V = 1/3lwh is the volume for a triangular prism and V = lwh is the volume for a rectangular prism.

Let's now solve for the triangular prism.

The length and width are the same as that of the cube. The cube's length and width is 4 in.

V = 1/3(4)(4)(6) = 32 cubic inches

Now Solve for the cube.

V = lwh = 4(4)(5) = 80 cubic inches

Total Volume = 80 + 32 = 112 cubic inches

Answer:

Slope is 3/4

Step-by-step explanation:

Each point given is an x and a y, like this (x, y)

For the top number (numerator) of your answer, subtract the y's from both points.

On top: 9 - 3

On the bottom (denominator) subtract the x's.

Below: 5 - -3

So slope is:

9-3 / 5 - -3

6/8

Simplify

6/8

= 3/4

The slope is 3/4.

Answer:

a) Vertex is at (-3, -1)

b) y-intercept is at (0,8)

c) x intercept is at (-4,0) and (-2,0)

d) x=-3

Step-by-step explanation:

The vertex of a parabola is the lowest or highest point, implying that all points are reflected across it. It's the only y value that doesn't have a corresponding pair.

For example, -1 and 1, -3 and 3, and so on.

The vertex is at (-3,-1) because it is the sole point without a corresponding y value (-3,-1)

The y-intercept is where the parabola meets the y axis or when the x value equals 0. To determine the y-intercept, simply find when x = 0.

intercept y: (0,8)

The x-intercepts are the same as the y-intercepts; you must determine where the parabola crosses the x-axis or when y = 0.

x intercept 1:(-4,0)

x intercept 2: (-2,0)

The axis of symmetry is also the x coordinate of the vertex which is 3 so

x = 3

Step-by-step explanation:

using the tangent ratio in the right triangle and the exact valu

tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{19\sqrt{3} }[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

[tex]\sqrt{3}[/tex] × y = 19[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

y = 19

--------------------------------------------------

using the cosine ratio in the right triangle and the exact value

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{19\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

[tex]\sqrt{3}[/tex] × x = 38[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

Answer:

A = 480 mm²

Step-by-step explanation:

the area (A) of a rhombus is calculated as

A = [tex]\frac{1}{2}[/tex] product of diagonals

The diagonals are perpendicular bisectors of each other , so

Δ XVW is a right triangle

using Pythagoras' identity in the right triangle , then

XV² + WV² = WX²

XV² + 24² = 26²

XV² + 576 = 676 ( subtract 576 from both sides )

XV² = 100 ( take square root of both sides )

XV = [tex]\sqrt{100}[/tex] = 10

then

XZ = 2 × XV = 2 × 10 = 20

and

WY = 2 × WV = 2 × 24 = 48

A = [tex]\frac{1}{2}[/tex] × XZ × WY = [tex]\frac{1}{2}[/tex] × 20 × 48 = 10 × 48 = 480 mm²
