Answer:

R: √(13)

Step-by-step explanation:

Distance formula:

r^2 = (x-h)^2 + (y-k)^2

Center: (h,k)=(-1,5)

Circle: all points of (x,y)=(-3,2)

r^2=(-3+1)^2 + (2-5)^2

r^2=(-2)^2 + (-3)^2

r^2= 4 + 9

r^2=13       ((r^2)^(1/2)) = 13^(1/2) = 3.6055

Answer:

The equation that matches the function shown is option;

C. y = sin\left (\dfrac{1}{2} \cdot x\right)

Step-by-step explanation:

The given graph of the function is a sinusoidal graph

The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;

x, {}      y

0    {}   0

π {}       1

2·π   {} 0

3·π {}    -1

4·π {}    0

We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0

Therefore;

y = the sine of half the x-value

Which is presented as follows;

y = sin\left (\dfrac{1}{2} \cdot x\right).
