State the amplitude, period, phase shift, and vertical shift of the function h(t)= cos (t+1)
oksano4ka [1.4K]

Answer:

Option b.

Step-by-step explanation:

We can easily solve this problem by using a graphing calculator or plotting tool.

The function is

h(t) = cos (t +1)

Please, see attached picture below.

By looking at the picture, we can tell that the amplitude is equal to 1

The function has a period of T = 2π

We can see there is no vertical shift.

It has a phase shift of +1. (Which moves the graph to the left)

Answer:

Option b.

The co-ordinate of point P is (x+3) and Q is (x-3). Then find d(P,Q). If coordinate of R is (x+2). Find d(Q,R).
kari74 [83]

Answer:

<h2>d(P, Q) = 6</h2><h2>d(Q, R) = 5</h2>

Step-by-step explanation:

The formula of a distance between two points A(a) and B(b):

<h3>d = |b - a|</h3>

We have P(x + 3), Q(x- 3), R(x + 2).

Substitute:

d(P, Q) = |(x - 3) - (x + 3)| = |x - 3 - x - 3| = |-6| = 6

d(Q, R) = |(x + 2) - (x - 3)| = |x + 2 - x - (-3)| = |2 + 3| = |5| = 5
