10 is proportional, while 11 is not. The answer for 10 is 1.5.

The first one is porportional the second one is not. We can figure this out by trying to figure out a pattern between the relationships.

6-4

12-8

24-16

We can see that the proportional relationship in the first one is 3-4, because if we divide each left one by 3 and the second one by 2, the number will be the same!

Find the area the sector.arc circle 10A. 16π mi²B. 34π/3 mi²C. 5π/3 mi²D. 9π mi²
erastova [34]
Answer:\frac{14\pi}{3}mi^2Explanation:

The<em> </em>area of a sector is given as:

\begin{gathered} Area\text{ = }\frac{\theta}{360}\times\pi r^2 \\  \\  \end{gathered}

The sector angle, θ = 360° - 255°

θ = 105°

The radius, r = 4 mi

Substitute these values into the equation to solve for the area

\begin{gathered} Area=\frac{105}{360}\times\pi\times4^2 \\  \\ Area=\frac{105}{360}\times16\pi \\  \\ Area=\frac{7}{24}\times16\pi \\  \\ Area=\frac{7}{3}\times2\pi \\  \\ Area=\frac{14\pi}{3}mi^2 \\  \end{gathered}

Please hurry!

See the graphs

<h2>Explanation:</h2>

First Case:

Here we have the following function:

h(x)=2sin(2x)-3

In order to graph this function, first let's take:

f(x)=sin(x)

Step 1. Compress horizontally this function by 1/2, so it becomes:

f_{1}(x)=sin(2x)

Step 2. Stretch vertically this function, so it becomes:

f_{2}(x)=2sin(2x)

Step 3. Shift the graph of the function three units down.

f_{2}(x)=2sin(2x)-3

Second Case:

Applying a similar method, we get:

Step 1. Compress horizontally this function by 1/2, so it becomes:

Step 2. Stretch vertically this function, so it becomes:

Step 3. Shift the graph of the function tow units down.

Finally, the graphs are shown below.
