Answer:

(0, -3) and (2, 1)

Step-by-step explanation:

There are 5 points marked on the graph: (±2, 1), (±1, -2) and (0, -3). These are solutions to the equation describing the function:

... y = x² - 3

Apparently, you are being asked to report the coordinates of any two of these points.

<em>Comment on the problem</em>

The wording "solutions to the function" is a bit odd. An equation has solutions—values of the variables that make it be true. A function is a relationship between values, a definition. There is nothing  to solve.

In the above we have assumed the intent is to find (x, y) pairs that match the function definition. Sometimes, we're interested in values of x that make y be zero. (x, y) = (±√3, 0) It isn't obvious what the intent of this question is.

Select the correct answer.A town park has two paths leading to the playground. One path is 2 miles from the road and the other p
damaskus [11]

Given:

There are given that the two paths and one path are 2 miles from the road.

Explanation:

Suppose the distance from the playground to the road is x.

To find the value x, we need to use the cos function;

So,

From the cos function in the given right angle triangle:

cos50^{\circ}=\frac{x}{2}

Then,

\begin{gathered} cos50^{\operatorname{\circ}}=\frac{x}{2} \\ 0.64=\frac{x}{2} \end{gathered}

Then,

\begin{gathered} 0.64=\frac{x}{2} \\ x=0.64\times2 \\ x=1.28 \\ x=1.3mi \end{gathered}

Final answer:

Hence, the correct option C.
