Answer:
∠ BOC = 42°
Step-by-step explanation:
Since OA and OC are perpendicular , that is at 90° to each other, then
∠ AOB + ∠ BOC = 90 , substitute values
5x + 8 + 6x - 6 = 90
11x + 2 = 90 ( subtract 2 from both sides )
11x = 88 ( divide both sides by 11 )
x = 8
Thus
∠ BOC = 6x - 6 = 6(8) - 6 = 48 - 6 = 42°
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Answer:
b) (4,-3) good luck with the rest
One with a capital A and one with a small a
no other difference
Step-by-step explanation:
Well, 3/5 hours equals 30 secs.This means that he started 3:30 hours ago .To find out what time was it you have to subtract 3:30 from the finishing time. So, 10:18-3:30=6:48.If you have any further questions please contact me.
