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>
The chances for my friend to be in my group are low given the probability, I say no.
Answer:

Step-by-step explanation:
As the line is perpendicular to
, we know that the slope of the line is
. As it passes through
, we know that it should be
.
-4×x+7 ≤ x-25
-4x+7≤x-25
-7 -7
-4x≤-32
÷-4 ÷-4
x≤8
