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

3% is the decimal 0.03 .
To make a number 3% bigger, multiply it by 1.03 .
The ' 1 ' part is the amount that's already there, and
the ' .03 ' part is the amount to be added onto it.
Answer:
ADB and ABC are similar
x = 8
Step-by-step explanation:
hypotenuse in ADB = 
since two triangles are similar,
solving for x, x=8
If -15 is equal to -0.2x, then 15/0.2=75
x=75
