The value is positive six
Step-by-step explanation:
Using cos ^2x+sin^2 x = 1
RHS = cos ^2x+sin^2 x = 1
Therefore,
LHS = cos ^2 x − cos ^4 x
= cos ^2 x ( 1 − cos ^2 x )
= cos ^2 x sin ^2 x
= ( 1 − sin ^2 x ) sin ^2 x
= sin ^2 x − sin ^4 x
= RHS
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36

You have 2x oranges and you add 5 more but you still have 23 apples more than oranges
Answer:
B
Step-by-step explanation:
The area between the curves y = d and y = f(x), between the limits x=a and x=b, is:
∫ₐᵇ (d − f(x)) dx
Alternatively, the area between the curves x = f(y) and x = a, between the limits y = c and y = d, is:
∫ᵈ (f(y) − a) dy
Answer A would give you the area between x = f(y) and the y-axis. It needs to include the − a term to be correct.
