Answer:
f(x) = + cosx or - cosx
Step-by-step explanation:
(2+tan^2x/sec^2x) -1 =(f(x))^2
=(( 1 + sec^2x)/sec^2x) -1
= 1 / sec^2x + 1 - 1
= 1 / sec^2x
= cos^2x
(f(x))^2 = cos^2x
f(x) = + cosx or - cosx
Answer: 0.35

Answer:
Let the x = # of pies Larry ate
Jesse ate 2x-5 pies
Total = 16

3x-5=16
3x=21
x = 7
Larry ate 7 pies.
