The answer is 120. Because inscribed angle is Half of the arc measure. Double 60 and we get 120.
Answer:
D
Step-by-step explanation:
sorry if i am incorrect but that is my best guess
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2
9= h/9
Mutiply both sides by 9
9*9= h/9*9
Cross out 9 and 9 , divide by 9 and then becomes h
9*9= 81
Answer: h= 81
Answer: 180 miles x 3 hours = 540
540/2 = 270
270 is the average speed
