A)
5 – 12i = 3 + 2i
or, 3 – 2i
or, – 3 + 2i
or, – 3 – 2i
b)
3 + 4i is 2 + i
Answer:
We have the three angles of a triangle as an equation, so we can add them together, and they equal 180.
So:
4x+10+12x-6+3x+5= 19x+9=180
19x=171 ... so: x= 171/19 = 9.
So ABC = 102 .. Obtuse angle
BAC = 46 .. Acute angle
BCA = 32 .. Acute Angle
Edit:
Angle 1 = 180 - BAC = 180 - 46 = 134
Angle 2= 180 - ABC = 180 - 102 = 78
<span>y - k = a(x - h)²
</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²
</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.
Vertex (5,8).
Answer:
1760
Step-by-step explanation:
12 inches in a foot so 5280x12 is how much inches in a mile
63360 inches in a mile
63360 divided by 36 inches
1760
Answer:
y3 - 120 y2 + 3600 y.
Step-by-step explanation:
Rearrange like terms to the same side of the equation:x2 yx = 60 - ySubstitute:60 - y2 yExpand the e.
hope this helps.
