Answer:
Parallel
Step-by-step explanation:
they have the same slopes
Answer:
see explanation
Step-by-step explanation:
The complex number z = a + bi is made up of 2 parts
a ← the real part and
bi ← the imaginary part ( always with the i in it )
given z = - 60i + 80
real part = 80 and imaginary part = - 60i
Multiply 3.25 x 5 + 0.68 x 18.5
16.25 + 0.68 x 18.5
Multiply 0.68 x 18.5 = 12.58
16.25 + 12.58
Add 16.25 + 12.58 = 28.83
Answer ~ 28.83
Answer: 889.66
Step-by-step explanation:
Volume of sphere is 4/3 \pi r3 and cylinder is \pi r2 h,
r=5
h=8
volume of sphere is 4/3 x 3.14 x 5x5x5 / 2 (since half of sphere) = 261.66
volume of cylinder is 3.14 x 5x5 x 8 = 628
total volume = 261.66+628 = 889.66
Answer:
1. 2m^2-2n^2
Step-by-step explanation:
1. (m-n)(m^2+mn+n^2)
m^2=m
n^2=n
=(m-n)(m+mn+n)=(m-n)(2m2n)
Multiple
=2m^2-2n^2
