Answer: y=-2x+5
Step-by-step explanation:
I am not sure if this is exactly what you are asking but all you have to do is plug the variables into the formula y=mx+b
Which should give you the above answer of y=-2x+5
Remember that for a graphic of a trigonometric functions of the form


is the amplitude of the function

is the midline of the trigonometric function
We know form our problem that

, so the amplitude of our function is 5. We also know that the

. So the midline of our function is the line

.
Using those two features we can conclude that the graph <span>that shows the height of the water at the dock at any time after midnight is: </span>
Answer:
60cm
Step-by-step explanation:
200*3/10=20*3=60
A. X is the number of years after 2000
2006-200 = 6 years.
Replace x with 6 and solve:
105(6)^2 + 680(6) + 4296 = 12,156
Answer for part a: 12,156
Answer for part B.
There was just over 12,000 in 6 years , to get to 21,500 would be a little over 9,000 more 9/12 = 0.75
6 years x .75 = 4.5 years
6 + 4.5 = 10.5 years round to 10 years for estimating purposes
Answer for part b: about 10 years
