The force would be 0.04.
This is found by using the formula:
F=mg sinθ
F = 0.01(9.8)sin (22.5)
F ≈ 0.04
$2
10%->.10
20x0.10=(2)
Jacquie saves up $2 if she refers a friend.
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>
