Step-by-step explanation: 9*1= 9 9*2= 18 9*3 = 27 9*4= 36 9*5=45 9*6 = 54 9*7=63 9*8= 72 9*9 81 9*10= 90
Since t is from 0 to 1 second, the time length is 1 second total.
replace t in the given equation with 1 and solve for x:
x = 4 cos(PI x 1 + PI/4)
X = 4cos(PI + PI/4)
x = 4cos(5PI/4)
x = 4(-cos(PI/4))
x = -2√2
