Answer:
1.63 cm (across the centerline from release)
Step-by-step explanation:
If we assume time starts counting when we release the weight from its fully-extended downward position, then the position at 1.15 seconds can be found from ...
h(t) = -7cos(2πt/4)
h(1.15) = -7cos(π·1.15/2) = -7(-0.233445) ≈ 1.63412 . . . cm
That is, 1.15 seconds after the weight is released from below the resting position, it will be 1.63 cm above the resting position.
__
If it is released from <em>above</em> the resting position, it will be 1.63 cm <em>below</em> the resting position at t=1.15 seconds.
Answer:
4/3
Step-by-step explanation:
Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3. Thus, the slope of the line connecting the two points is
m = rise / run = 12/9 = 4/3
It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg. Then
m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put
0.6
x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]
I'm sorry if it was confusing, I hope it helped!
