Answer:
B. d = 4 cos(π/3 t)
Step-by-step explanation:
As at t=0 the amplitude is 4 cm, so the simple harmonic motion will be in cosine form. As in case of sine function, the value of function at t=0 is 0.
sin 0=0
We know that,
y = a. cosb(t + c) + d
Period = 2 π / b
Horizontal shift or phase shift is c,
Amplitude is a,
Vertical shift is d.
As in this case the amplitude is given to be 4, hence = 4
Also the period is given as 6.
That is, 2π/b = 6
b = 2π/6 = π/3
Here horizontal and vertical shifts are 0.
That is c = 0 and d = 0
Plug those values in the above form, we get
y = 4.cos π/3 (t + 0) + 0
y = 4 cos (π/3)t
Answer: B. d = 4 cos(π/3 t)
Hope this will helpful.
Thank you.
Angle 1 = 4x - 16
angle 2 = 2x + 10
4x - 16 + 2x + 10 = 90
combine like terms
6x - 6 = 90
add 6 to both sides
6x = 96
divide both sides by 6
x = 16
angle 1 = 4x - 16 = 4(16) - 16 = 48
angle 2 = 2x + 10 = 2(16) + 10 = 42
16 pts is equal to 256 fluid ounces. 16 pints is greater than 100 fl. Hope this helps ! (:
Huh english is this spanish !
Answer:
Expressions equivalent to 16x - 12 -24x + 4.
-8x - 8 , - (8x + 8) , 8 (-x -1) , -8 (x + 1)
Step-by-step explanation:
16x -12 -24x + 4
Arranging like terms, 16x - 24x - 12 + 4 = -8x - 8
Taking common minus, = - (8x + 8)
Taking common 8, = 8 (-x -1)
Taking common -8, = -8 (x +1)
