Answer:

Frequency is expressed in Hertz, which is simply cycles per second. If a tuning fork (or anything else, for that matter) vibrates 1 time each second, it's frequency is 1 Hz. So then, if it vibrates 4280 in 20 seconds, then 4280÷20=214 cycles per second = 214 Hz.

What is the slope of the line plotted below? (-2,-1) (4,2) A. 1 B. 2 C. -0.5 D. 0.5
Dmitry [639]

Answer: D. 0.5

Explanation:

The slope formula is y2-y1/x2-x1.

2-(-1)/4-(-2) = 2+1/4+2

2+1/4+2 = 3/6 = 1/2

1/2 = 0.5

The slope is 1/2, or 0.5.
