Answer:
1.9 degrees per second
Step-by-step explanation:
The angle α the line makes with the water can be described by ...
Sin = Opposite/Hypotenuse
sin(α) = 10/(25 -1.9t)
Taking derivatives gives ...
α'·cos(α) = -10(-1.9)/(25 -1.9t)²
Then the rate of change of the angle at t=0 is ...
α' = 19/(25²·cos(α))
Of course, cos(α) = √(1 -sin(α)²) = √(1 -(10/25)²) = √(21/25), so we have ...
α' = 19/(125√21) . . . radians/second
α' ≈ 0.033269 radians/s ≈ 1.90 degrees/s
Answer:
<h2>slope = -10/7</h2>
<u>Step-by-step explanation:</u>
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7
Answer:
West
Step-by-step explanation:
Clock wise goes to the right, and There's 4 directions 90° Apart. So we basically cycle through the directions by 3
North -> east -> South -> West

Answer:
A = 65
Step-by-step explanation:
A = 1/2(7+6)·10
A = 5(7+6)
A = 5(13)
A = 65
