Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, 
Period is 
divided by the coefficent of x, in this case, 
Phase shift, is how much you sum or subctract from x inside the sine, in this case 
.
Midline you get by hiding the sine and reading what's left, in this case, -4.
Answer:
3x-2
Step-by-step explanation:
JK =JL+LM
5x-8=JL +(2x -6)
JL = 5x-8 -2x+6
JL = 3x-2

7x+72xy
Step-by-step explanation:
7x+8x(9y)=7x+72xy
Answer:
Step-by-step explanation:
Given is the shape of a trapezoid.
Therefore,
Area of the trapezoid
If A=w(50-w)
A=50w-w^2
dA/dw=50-2w
d2A/dw2=-2
Since the acceleration is a constant negative, that means that when velocity, dA/dw=0, it is at an absolute maximum for A(w)...
dA/d2=0 only when 50=2w, w=25
So as the case with any rectangle, the perfect square will enclose the greatest area possible with respect to a given amount of material to enclose that area...
So the greatest area occurs when W=L=25 in this case:
A(25)=50w-w^2
Area maximum is thus:
Amax=50(25)-(25)^2=625 u^2
