Problem 19.1. Find the amplitude, period, a
phase shift and the mean of the following si-
nusoidal functions.
(a) y = sin(2x - 7) + 1
(b) y = 6 sin(2x) - 1
(c) y = 3 sin(x + 2.7) + 5.2
(d) y = 5.6 (sin (x-7) – 12.1)
(e) y = 2.1 sin ( + 44.3) – 9.8
(1) y = 3.9 (sin(22.34(x + 18)) -- 11)
(g) y=11.2 sin ((x -9.2)) + 8.3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
