Answer:
B
Step-by-step explanation:
Its the only one that makes sense
Answer:
the first one is true:)
Step-by-step explanation:
f(x) = log2 x
f(40) = log2 40
40 = 2^y
2^5 = 32 and 2^6 = 64
so f(40) lies between integers 5 and 6.
The factors of 56 include
1 by 56
2 by 28
4 by 14
7 by 8
Answer:
see explanation
Step-by-step explanation:
Using the identity
tan²x = sec²x - 1
Consider left side
sec²x + tan²x
= sec²x + sec²x - 1
= 2sec²x - 1
= right side , thus verified
