Throughout the day, the depth of water at the end of a dock varies with the tides. The function h(t)=5cos(0.5t-2)+7 represents t
dybincka [34]
Remember that for a graphic of a trigonometric functions of the form f(x)=Acos(Bx+C)+D
A is the amplitude of the function 
f(x)=D is the midline of the trigonometric function 

We know form our problem that A=5, so the amplitude of our function is 5. We also know that the D=7. So the midline of our function is the line h(t)=7. 

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>

I don't know how to find the value of x in the isosceles triangle.
frez [133]

Answer:

x=4

Step-by-step explanation:

split the triangle into two and you will get another smaller triangle as shown in what I have drawn

so notice that there's a right angle?? this means that this is a right angle triangle and you can use Pythagoras theorem to solve it

so by Pythagoras theorem, 5^2= 3^2 + x^2

then you can solve for x

A gaming system is marked down from 290 to 188. What is the percentage of the discount?
yuradex [85]
Let P = percent of discount

(290-188)/290 = P/100

102/290 = P/100

290P = (102)(100)

290P = 10,200

Solve for P to find your answer.
