Answer:
15u^3 + 8u^2 - 6u + 13
Step-by-step explanation:
(7u^3 + 8u^2 + 8) + (8u^3 - 6u + 5)
= 7u^3 + 8u^2 + 8 + 8u^3 - 6u + 5
= 7u^3 + 8u^3 + 8u^2 - 6u + 5 + 8
*Now add the like terms
= 15u^3 + 8u^2 - 6u + 13
And that is all your can do!
Answer: magnitude ab = 9.06
Step-by-step explanation:
The vector coordinates will be represented with ( X , Y )
Magnitude of ab will be
ab^2 = (X2 -X1)^2 + (Y2 -Y1)^2
ab^2 = (2 -1)^2 + (-3 -6)^2
ab^2 = 1^2 + 9^2
ab^2 = 1 + 81
ab = 9.06
Answer:
-16 - 30i
Step-by-step explanation:
(3-5i)^2 = (3-5i) * (3-5i)
Applying the "FOIL" method of expanding this expression through multiplication, we get:
9 - 15i - 15i - 25 (since i^2 = -1)
Simplifying this result, we get -16 - 30i
