Derivitive of cosx=-sinx
dy/dx sinx=cosx
and use chain rue
2cosx=-2sinx
2cos2x=-4sin2x
so
-2sinx-4sin2x id the deritivitve
Answer:
Total seashells = (6g + 10) seashells.
Step-by-step explanation:
Given that Mario collected 3g seashells.
Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.
It says to write the number of seashells they collected together in terms of g.
Total seashells = Mario's seashells + Jasmine's seashells.
Total seashells = 3g + (3g+10).
Total seashells = 6g + 10.
Hence, Total seashells = (6g + 10) seashells.
Q^2 - 125 = 0

Answer: 9πcm²
Step-by-step explanation: area of the square= 36cm²
Therefore, the area of one side= √area = √36 = 6cms
Since the circle is touching the sides of the square, the side of the square = the diameter of the circle
Therefore the radius of the circle= side/2 = 3cm
The formula for the ares of the circle is πr²
π*3*3 = 9πcm²
