Yas, I'm learning this

remember
f'(a+b)=f'(a)+f'(b)
and
f'(cos(x))=-sin(x)
and
f'(g(x))=f'(g(x))g'(x)
and
f'(xⁿ)=nxⁿ⁻¹


f'(a⁷+cos(7x))=
f'(a⁷)+f'(cos(7x))=
7a⁶+f'(cos(7x))f'(7x)=
7a⁶-sin(7x)(7f'(x))=
7a⁶-sin(7x)(7*1)=
7a⁶-sin(7x)(7)=
7a⁶-7sin(7x)


f'(a⁷+cos(7x))=7a⁶-7sin(7x)

the sum of areas of two circles is 80 square meters find the lencgh of radius of each circles if one of them is twice as larger
klemol [59]
Area of a cirlce=πr²
we have two radius:2r and  r
area of the cirlce₁ + area of the circle₂=80 m²
area of the circle₁=π(2r)²
area of the circle₂=πr²
Then, we can suggest this quation:

π(2r)²+πr²=80

4πr²+πr²=80
π(4r²+r²)=80
π(5r²)=80
5πr²=80
r²=80/5π
r=√(80/5π)≈2.26

radius of the largest cirlce=2r=2(2.26)=4.51

Answer: the radius of the largest circle is 4.51 m
