Answer:

A, y = {x²+ 6   x < 3

         {-x + 6   x ≥ 3

Step-by-step explanation:

the parabola (the u shaped graph or the graph that is on top) is expressed by the function x² + 6, as it is 6 units up from the origin (0,0)

the line is expressed by the function -x + 6, as its first reflected across the x axis from the origin (0,0) and is then shifted 6 units up

these functions on this graph represent a piecewise function

looking at x² + 6, we see that it has an open circle on (3, 15). this means that the x coordinate 3 is not included in the solution to the function, and any x values that would be included are less than 3. in an inequality, this is expressed as x < 3

looking at our answer choices, this matches answer A. but let me continue with the explanation in case you run into a question that doesnt have it that easy

when we look at -x + 6, we see that it has a closed circle on (3,4) (approx (3,4), not sure about y-coordinate but its still the same). a closed circle means that the x coordinate 3 is included in the solution, and any numbers <em>greater than 3</em> are included in the solution. as an inequality, this is expressed as x ≥ 3

again we look at our answer choices and see that A is the only choice that supports both of these functions, so A is our answer

In a right triangle whose area is 12, each leg is as long as the side of a certain square. What is the area of the square?
kakasveta [241]
The area of a Square is 144 because 12x12 is 144 and if both sides are 12 then that equals 144. 

Hope this helps!

Area of a circle = pi*r^2.

Here, A = 380.13 mi.  Unfortunately, "mi" is NOT a unit of area.

So I will assume that the problem should read   A = 380.13 sq. miles.
                                                                    380.12 mi^2
Thus,   380.13 mi^2 = 3.14*r^2, and r^2 = ------------------- 121.057 mi^2
                                                                           3.14

The radius is the sqrt of 121.057 mi^2:  11.00 miles.

The diam. is twice that, or d = 22.00 miles.

Scenario
Elena-2011 [213]

The function that gives the shares received by a post whereby each friend

shares the post a constant multiple of times each day is exponential.

<h3>Responses;</h3>
  • Ben's social media post: <u>2 × 3ⁿ</u>
  • Carter's social media post: <u>10 × 2ⁿ</u>

<h3>Methods by which the above expressions are obtained:</h3><h3 /><h3>Ben's social media posts;</h3><h3 /><h3>Given:</h3>

The given table of values for Ben's social media post is presented as follows;

\begin{tabular}{|c|c|}Day&Number of shares\\0&2\\1&6\\2&18\end{array}\right]

<h3>Solution:</h3>

The number of shares triples everyday, therefore, the number of shares form a geometric progression, with a common ratio of r = 3, and a first term of <em>a</em> = 2

The function for the number of shares of Ben's post is, tₙ  = a·rⁿ

Which gives;

  • Ben's social media post shares on day <u><em>tₙ</em></u><u> = 2·3ⁿ</u>

<h3>Carter's social media posts;</h3><h3 /><h3>Given;</h3>

Number of friends Carter shared his post with = 10 friends

Number of people each of the 10 friends shared with each day = 2 people

<h3>Solution;</h3>

The exponential function for number of shares received by Carter is therefore, <u>tₙ = </u><u>10×2ⁿ</u>

  • Carter's social media post shares on day <em>n</em>: <u>10 × 2ⁿ</u>
