If d = 20 and C = 20π

1 answer:

8 0

If d = 20 and C = 20π, then r = 10.
If d = 26 and C = 26π, then r = 13.
If r = 1/2 and C = π, then d = 1.
If r = 7 and C = 14π, then d = 14.
If r = 6 and C = 12π, then d = 12.
If r = 50 and C = 100π, then d = 100.
*Note, r= 1/2×d or d=2×r

I would say b the reason is because -2 is on the x and -6 in on the y so it would be left then down.

in the function y-1=1/2(x-6)^2 what effect does the number 6 have on the graph, as compared to the graph y=x^2

butalik [34]

Answer: The graph is shifted 6 units to the right.

Step-by-step explanation:

It is important to remember that:

When $f(x-k)$ , then the function is shifted "k" units to the right.

Knowing this and given the quadratic parent function $y=x^2$ and the function $y-1=\frac{1}{2}(x-6)^2$ , you can observe that one of the transformations is the following:

$f(x-k)$

Where:

$k=6$

Therefore, you can notice that the effect is:

The graph is shifted 6 units to the right.
