Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?
Scrat [10]

Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.

Question 13 <br>y = - X + X^2
ankoles [38]
We have the following function that is a quadratic function:

y=-x+x^2

So the graph of this function is shown in the figure below. This is a parabola as you can see. The roots of this functions, that is, the x-intercepts are:

y=-x+x^2 \\ y=x(x-1) \\ \\ x_{1}=0 \ and \ x_{2}=1

As you can see in the figure. This function decreases from (-\infty,0.5) and increases from (0.5, \infty)

Finally, it is important to note that the vertex is the point:

V(0.5,-0.25)

The answer is the second graph.
