Answer:
1/2 + 5/2 i
Step-by-step explanation:
(-5+i) i
---------* --------
2i i
cannot have i in the denominator so we multiply by i
(-5+i) i -5i + i^2
---------* -------- = ----------------
2i i +2i^2
remember i^2 = -1
-5i + -1 -1 -5i
= ---------------- = ------------------
+2(-1) -2
get rid of the negative in the denominator by multiplying the top and bottom by -1
(-1 -5i) * -1
= ------------------
-2*(-1)
(1 +5i)
= ------------------ = 1/2 + 5/2 i
2
The probability of it is 2/5
Answer:
Step-by-step explanation:
1). Geometric mean of a and b = 
Therefore, geometric mean of 2 and 50 = 
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly, 
d² = 6 × 30
d = √180
d = 6√5
And 
c² = 30 × 24
c = √720
c = 12√5
Answer:
b because it just is
Step-by-step explanation:
Answer:
$7.85
Step-by-step explanation:
2 pizzas at 11.99=23.98
4 soft drinks at 1.85=$7.40
23.98+7.40=31.38
31.38/4=7.845
Each friend pays $7.845, or $7.85 .........
