Differentiating w.r.t y,
We get,
<span>2 x (d x/d y) + y (d x/d y) + x + 2 y = 0 </span>
<span>Put
d x/d y = 0 </span>
The equation becomes:
<span>x=2 y </span>
<span>substituting into main equation
We, get
3 y^2 =9 </span>
y= √3
x = <span>± 2√3</span>
Answer:
23 times f
Step-by-step explanation:
Answer:
108 pi
Step-by-step explanation:
The formula for volume of a cone is (1/3) * π * r² * h
36 pi = (1/3) * π * r² * h
108 pi= π * r² * h
108 = r² * h
Formula for volume of a cylinder: πr²h
108 pi
5 x 3 = 15
30 x 3 = 90
15+90=105
so that person paid $105 for that day
