Answer:
12.53 miles
Step-by-step explanation:
6² + 11² = x²
36 + 121 = x²
157 = x²
x = 12.53 miles
Step-by-step explanation:
e = 20sin(πt/4 - π/2)
= 20[(sinπt/4)(cosπ/2) - (cosπt/4)(sinπ/2)]
Used sin(x - y) = sinxcosy - cosxsiny.
= 20[0 - cosπt/4]
Since cosπ/2 = 0 and sinπ/2 = 1.
= -20cosπt/4.
Answer:
C
Step-by-step explanation:
If the y and x changed places, then, the point was rotated half a full rotation around, which is 180 degrees
Thus, the answer is C
