The wavelength of yellow light in a spectrum is about 0.00002 inches. Which number best approximates this length as a power of 10?
A. 2 x 10-5
B. 2 x 10^5
C. 2 x 10-4
D. -2 x 10^5

since the 2 is the 5th digit after the decimal, scientific notation will be 2*10^-5 thus choosing

Thus choice A is the correct answer.

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
