Answer:
$400
Step-by-step explanation:
Add The two things together
325+75= 400
5 m/sec or 300m / min
using speed =
change 5 min 20 sec to seconds = (5 × 60) + 20 = 320 sec
speed = = 5m / second or
speed = 60 × 5 = 300m / minute
The angle between two vectors is:
CosФ = u - v / Magnitude(u) x magnitude(v)
Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)
Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)
u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11
cosФ = -11 / sqrt(53) x sqrt(5)
cosФ = -11sqrt265) / 265
Ф =cos^-1(-11sqrt265) / 265)
Ф=132.51 degrees.
