Answer:
Step-by-step explanation:
hello :
sin x + 2 sin x cosx = 0 equivalent to : sinx(1+2cosx) =0
sinx=0 means : general solution is : x= kπ....k in Z
1+2cosx=0 means : cosx= -1/2 general solution is : x= ±π/6+kπ...k in Z
Answer:
The perimeter of the given rectangle = 20 units.
Step-by-step explanation:
Length of the rectangle = 6 units
The width of the rectangle = 4 units
Now Perimeter of the Rectangle = 2 ( LENGTH + WIDTH)
⇒Here, perimeter = 2 ( 6 units + 4 units ) = 2 x ( 10 units)
= 20 units
Hence, the perimeter of the given rectangle = 20 units.
Answer:
x = 1/2
y = 24
Step-by-step explanation:
y = 12 / x
y = 6 / x²
12 / x = 6 / x²
x² / x = 6 / 12
x = 1 / 2
y = 12 / x
y = 12 / (1/2)
y = 24
