We want to simplify √(-48).
Note that
i² = -1 by definition.
Therefore
Answer: c.
Answer: d)
Step-by-step explanation:
7 is the opposite
25 is the hypotenuse
24 is the adjacent
if u refer back to SOH CAH TOA
cos = adj divided by the hyp
cos K = 24/25
*please make sure to double check for yourself or get another person to look it over just incase*
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36
29
(4 hundred + 0 tens + 5 ones) + (1 ten) = 4 hundred + 1 ten + 5 ones
... = 415
