(1) will write us of the following form

\dfrac{dy}{dx}+y^2\sin x=0\\ \\


(2) [do not it need explanation]

\dfrac{dy}{dx}=-y^2\sin x\\ \\


(3) Left place variable "y" and right place, variable "x" like this

\dfrac{dy}{y^2}=-\sin x\, dx\\ \\

(4) Integrate both members 

\displaystyle
\int \dfrac{dy}{y^2}=\int-\sin x\, dx\\ \\

(5) Solve us the integrals

-\dfrac{1}{y}= \cos x+C

(6) Isolate variable "y"

\boxed{y=-\dfrac{1}{\cos x+C}}

C: any cosntant

Find the surface area of the pyramid shown to the nearest whole number. The base is a regular hexagon.
Fiesta28 [93]
The surface area of the pyramid will be given as follows:
Area of triangles:
A=1/2×base×height
A=1/2×12×18
A=108 m²
Area of 6 triangles is given by:
A=108×6=648 m²

Area of the hexagon:
A=6×1/2×12×6√3
A=374.123m²

Total surface area:
SA=648+374.123
SA=1022.123 m²~1022 m²

Answer: C] 1022 m²
