Answer:
a, r = A sin (ωt±Ф) =5 Sin (3.9 t ± 2π) b. A e^-ωt = 5 e^-3.9 t
Step-by-step explanation:
ω =2πr/t =2π*5/8 =3.9 rad/sec, amplitude will be 5 (0, 5 )
Answer:
16 children
Step-by-step explanation:
80% of 20 children comes out to 16 children who are of age 5.
If desired, rewrite "80%" as "0.80" and use that 0.80 as the multiplier of 20:
0.80(20 children) = 16 children.
Answer:
<u>The equations for each function:</u>
- A(t) = 60 - 6t
- B(t) = 42 - 3t
<em>The lines plotted, see attached</em>
<u>The point at which both the snowmen have same height:</u>
- 60 - 6t = 42 - 3t
- 6t - 3t = 60 - 42
- 3t = 18
- t = 6
<u>The required interval is </u>
7 . 3
--- × ------
10. . 6
