sqrt(x^2) = sqrt(-4)
sqrt(-4) = 2i, or -2i
Step-by-step explanation:
If you put into a calculator "Sin(6)+Cos(6)+3Sin(2)Cos(2)", you get 1.20368506925. Hope that helps
Answer:
No, not correct.
Step-by-step explanation:
Note that 8 * 4.3 can be broken up as follows:
8 * (4 + 0.3)
and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).
Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
i believe it would be 5.25
12-5=7
7*12=84
84/ 16 = 5.25
i hope this helps
