Assuming the logarithm is base
, you have
Answer:
there are 6.45 or 6.5 square cm in one square inch
Step-by-step explanation:
(f+g)(x) is basically equal to f(x)+g(x), so you're just adding the two functions together.
What is 68 divided by 18...which gives you 3.8
You need to use the identity
cos(90-u)=sin(u)
if u=x-20
cos(90-x+20)=sin(x-20)
cos(110-x)=sin(x-20)
substituting in the original function
cos(110-x)=cos(42)
for the functions to be equal there input must be equal
110-x=42
x=68
