Answer:
Both/Neither.
Step-by-step explanation:
For the circle, the area is π(6)^2= 36π. 3/4 of that is 27π. Now, for the ring, area of outer circle is 36π. The area of inner circle is 9π. So, area of ring is 27π. That means, both will take the same amount of paint.
goal:tan^5x=tanx(sec²x-2sec²x+1)
proof: from l.h.s to r.h.s
tan^5x=(tanx)^5=((tanx)(tan²x)(tan²x))
from trigonometry identity
(tan²x)=sec²x-1
tan^5x=(tanx(sec²x-1)(sec²x-1))
=(tanx(sec^4x-sec²x-sec²x+1))
=(tanx(sec^4x-2sec²x+1))
proved
Answer:
d) 8
Step-by-step explanation:
Answer:
Option C and E are correct.
Step-by-step explanation:
We need to solve the following equation
(2x+3)^2=10
taking square root on both sides
Now solving:
So, Option C and E are correct.
