Answer:

See below

Step-by-step explanation:

1. Graph the function

(a) Create a table containing a few values of x and y

Your function is not linear, so you will have to plot several x,y pairs to get a smooth curve.

I chose x = -4, -2, 0, 2, 4.

\begin{array}{rr}\mathbf{x} & \mathbf{y}\\-4 & -2.00 \\-2 & -0.59 \\0 & 0.00 \\2 & 0.46 \\4 & 0.83 \\\end{array}

(b) Draw your axes

They have already given you a blank graph, so you can scale both axes from -5 to +5.

(c) Plot your points

Draw dots at the coordinates of each point ( Fig. 1).

(d) Draw the graph

Draw smooth lines through the points.

You can't draw to the left below x = -4, because that gives you imaginary values for y.  However, you should extend the line to the right edge of the plot area.

Your graph should look like Fig. 2.

2. Range

The range is the spread of the y-values (minimum to maximum distance).

From the graph, the minimum value is -2, and there appears to be no upper limit

\text{In interval notation, the range is $\large \boxed{\mathbf{[-2, \infty)}}$}

2. Domain

The domain is the set of all possible x-values that will make the function work.

We see from the graph that x cannot be less than -4, but there appears to be no upper limit to its value.

\text{In interval notation, the domain is $\large \boxed{\mathbf{[-4, \infty)}}$}

What single decimal multiplier would you use to increase by 9% followed by 3% decrease
MaRussiya [10]

Answer:

= 94

Step-by-step explanation:

To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2. The answer is £110 x 1.2 = £132.

so to workout an increase of 9% followed by 3% we would do:

9% - 3% = 6%. convert = 0.06 = 100-6 = 94 converted into 0.94 x 100 = 94

In the figure below, BCA ~ STR. Find cos C, sin C, and tan C. Round your answers to the nearest hundredth.
arsen [322]

Answer:

\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63

Step-by-step explanation:

According to the trigonometric ratios in aright triangle :

\sin x =\dfrac{\text{Side opposite to x}}{\text{Hypotenuse}}\\\\\cos x =\dfrac{\text{Side adjacent to x}}{\text{Hypotenuse}}\\\\\tan x=\dfrac{\sin x}{\cos x}

Given:  ΔBCA ~ ΔSTR

Since , corresponding angles of two similar triangles are equal.

So, ∠C = ∠T                            ...(i)    [Middle letter]

In triangle STR

\sin T=\dfrac{\text{Side opposite to T}}{\text{Hypotenuse}}\\\\=\dfrac{26.4}{30.9}\approx0.85\\\\\cos x =\dfrac{\text{Side adjacent to T}}{\text{Hypotenuse}}\\\\=\dfrac{16.2}{30.9}\approx0.52\\\\\tan T=\dfrac{\sin T}{\cos T}\\\\=\dfrac{0.85}{0.52}\approx1.63  ...(ii)

From (i) and (ii), we have

\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63

instead of P+2x = y it should be P-2x=y

 so then it is P-2x/2 =y

A bag contains the letters from the words SUMMER VACATION. You randomly choose a letter A, and do not replace it. Then you choos
ss7ja [257]
<h3>Hello there i hope you are having a good day :) Your question : A bag contains the letters from the words SUMMER VACATION. You randomly choose a letter A, and do not replace it. Then you choose another letter A. What is the probability that both letters are A’s? Write your answer as a percent, with the percent symbol. If needed, round to the nearest tenth. </h3><h3>Firstly the word is SUMMER VACATION there are 14 letters in this word and 2 of them with the letter A So this would be 2/14 and 1/7 Then there is 13 letters because we used one already so it would be 1/13 Then the second A would equal 1/13 and this would be 1/7 and 1/13 you would times both given 1/91 now written that in percent with a percent symbol 1.0989011% So this would be 1.91%</h3><h3>Hopefully that helps you ❤</h3>
