Answer:

From the Law of cosines we see that Line AB^2 (or side c^2) equals

AB^2 = a^2 + b^2 -2ab *cos (C)

AB^2 = 6*6 + 7*7 -2*6 * 7 * cos(59)

AB^2 = 85 -84 * 0.51504

AB^2 = 85 - 43.26336

AB^2 = 41.73664

AB = 6.4603900811

AB = 6.5 (rounded)

A bird goes from a higher location to a lower location at a
hammer [34]

Answer:

30(-2) = -60

Step-by-step explanation:

The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)

We need to find the equation that models the change in the bird's position at 30 seconds.

Distance = speed × time

change in position = (-2) × 30

= -60

Hence, the correct option is (B).
