Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:
To calculate how long will it take for the rock to reach the surface of the water, we need to set 
. So:
Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>
Y=cos(2x+pi) - 2
y= - cos(2x) - 2
{ Since cos(x+pi) =-cos(x)}
The ordered pairs would be,
(1, 8.5)
(2, 8)
(3, 7.5)
(4,7)
(5, 6.5)
(6, 6)
I got the ordered pairs from the question since it stated that the length of the candle decreased .5 every hour. I just corresponded the hour to the length of the candle.
I hope this helped!
Brainliest answer is always appreciated!
Answer:
linear
Step-by-step explanation:
The easiest (if not the only) way to solve this, is to check whether the slope at each point stays constant, or not. And in general, see how the rate rate of change evolves. In other words:
- 6.5 / 5 = 1.3
- 13 / 10 = 1.3
- 19.5 / 15 = 1.3
- 26 / 20 = 1.3
- 32.5 / 25 = 1.3
- 39 / 30 = 1.3
As you can see " in every step to the right, the function goes up by 1.3 " --> constant
So, the function is linear
