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
Answer:
Step-by-step explanation:
Hypotenuse squared = one leg square plus the other leg squared.
H^2=L1^2+L2^2
L2^2=H^2-L1^2
L2^2=14^2-3^2
L2^2=196-9
L^2=187
L2=√187
L2=13.7
L2 is approximately equals to 14

It’s 3/2 you can look at the the point (0,1) and (2,4) you can use a method called rise over run you got up 3 over 2 units to get to the next point
