Hope this helps.
Answer and Step-by-step explanation:
Given Asin(wt + phi), we know that sin (A + B) = sinAcosB + sinBcosA. This means:
Asin(wt + phi) = Asin(wt)cos(phi) + Asin(phi)cos(wt).
Let Acos(phi) = c2 and Asin(phi) = c1 we have:
Asin(wt + phi) = c2sin(wt) + c1cos(wt)
Answer:
1.83 hours
Step-by-step explanation:
Time is inversely proportional to speed
Implies that T = k/R, where k is the constant of proportionality
Thus, the product T × R is a constant for any given valued of R,T.
Hence, 3 × 14 = t × 23
t = (3×14) ÷ 23
t = 1.83 hours
