Algebra 2 Solve: f(x)=x^2-9

1 answer:

7 0

This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3

f(x)=(x-3)(x+3)

So your solution when you set f(x) to 0 would be -3 and 3.

What is the minimum number of angles required to determine the Cartesian components of a 3D vector and why?

Reika [66]

Answer: 3

Step-by-step explanation:

The 3D vector consists of 3 axes, let's say x, y and z.

Now, a vector P lies in all of them.

So, the angle it makes with x axis is α

The angle it makes with y axis is β

The angle it makes with z axis is γ

So, to determine the Cartesian components or to resolve the vector into it's Cartesian components we need 3 angles with each axis.
