Find the amplitude, period, and phase shift of f(x) = –2sin (7x + 7).

Amplitude:2, period:0.9 and phase shift:7

Step-by-step explanation:

In a function with the form y=Asin(Bx+c)+D, and given the function f(x) = –2sin (7x + 7), we get that:

A is the amplitude: 2

Period is given by 2pi/B, so 2pi/7=0.9

Phase shift is c: 7

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

they would have to work 32 hours.
