Find the distance between 5 + 4i and 9 + 3i.​

Mathematics
1 answer:
Burka [1]3 years ago
4 0

Answer:

Distance = √17

Step-by-step explanation:

We are looking for the distance between 5 + 4i and 9 + 3i.

This is as equal to saying we have two points in the plane, whose coordinates are; (5, 4) and (9, 3)

Distance between the 2 points will be;

D = √[(5 - 9)² + (4 - 3)²]

D = √(16 + 1)

D = √17

Express each cubic function below in terms of linear factors.a)f(x)=x³-6x²-27xb)f(x)=x³-16x²c)f(x)=x³+16x²
nirvana33 [79]

Answer:

a) x (x-9) (x+3)

b) x (x+4)(x-4)

c) (x)(x)(x + 16)

Step-by-step explanation:

We're going to equal the functions to zero and find their roots by factorizing:

a) f(x)=x³-6x²-27x

x³-6x²-27x = 0

x(x²-6x-27) = 0

⇒x (x-9) (x+3)

b) f(x)=x³-16x

x³-16x = 0

x (x²-16) =0

⇒x (x+4)(x-4)

c) f(x)=x³+16x²

x³ + 16x² = 0

x² ( x +16)

⇒(x)(x)(x + 16)
