The answer would be -fg But, I'm not so sure about the graph so sorry!
Answer:
Question 1: The hours that will pass between two consecutive times, when the water is at its maximum height is π hours
Question 2: Sin of the angle is -0.8
Step-by-step explanation:
Question 1: Here we have h(t) = 4·cos(t) + 10
The maximum water level can be found by differentiating h(t) and equating the result to zero as follows;
∴ sin(t) = 0
t = 0, π, 2π
Therefore, the hours that will pass between two consecutive times, when the water is at its maximum height = π hours.
Question 2:
B = (3, -4)
Equation of circle = x² + y² = 25
Here we have
Distance moved along x coordinate = 3
Distance moved along y coordinate = -4
Therefore, we have;
Sinθ = sin(-53.13) = -0.799≈ -0.8.
Yes
Reason - figure b has been increased by 3 (x3 for each side)
Eg. figure b - 1. Figure a - 3
12 goes into 276 23 times.
Hello there!
I see you got some work done already, but I guess you just wanted to double check! :)
3n + 8 = 20
3n = 20 -8 (Subtract 8 on both sides).
3n = 12 (Combine like terms).
n = 4 ( divide both sides by 3)
There you have your answer! :D
Hope this helped!
