X(ab-cd)=15m
x=15m/(ab-cd)
Answer:
4 option D
Step-by-step explanation:
Note that log2(2^n)=n
Thus we have:
Log2(2)+log2(8)=1+log2(2³)=1+3=4
Answer:
a
Step-by-step explanation:
4=-(-1+1)^2+4
Please be careful in the future regarding the options. These options look like cos of 2x, rather than cos(squared) of x.
The answer is B) -cos²(x)
(sin(x) + a) (sin(x) - a) = -cos²(x)
