Question

algebra

Answer 1

This is \(\sf \color{red}{not}\) linear algebra.

Answer 2

i thought it is algebra

Answer 3

To find the magnitude, speed, \(|\sqrt{a^2+b^2}|\), where a = 3, b = 4. Now, to finf direction,
tan(\(\theta\)) = \(\frac{b}{a}\)

Answer 4

You don't need those \(|\) dude. \(\sqrt{\ldots }\iff |\sqrt{\ldots}|\)

Answer 5

magnitude = 5 m/s and direction theta = 53 degree

Answer 6

Hmm...that's how I remember it. But I guess I should check b4 hand next tym. Thanks @wio

Answer 7

and 53 degree would be northeast right????

Answer 8

Remember that \(|x|
\iff \sqrt{x^2}\) and \(\sqrt{x} \iff |\pm \sqrt{x}|\)

Answer 9

Algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis.
For historical reasons, the word "algebra" has several related meanings in mathematics, as a single word or with qualifiers.

Answer 10

Algebra can essentially be considered as doing computations similar to that of arithmetic with non-numerical mathematical objects.[1] Initially, these objects represented either numbers that were not yet known (unknowns) or unspecified numbers (indeterminate or parameter), allowing one to state and prove properties that are true no matter which numbers are involved. For example, in the quadratic equation
ax^2+bx+c=0,

Answer 11

IN this case \(x=-3\), \(y=-4\)\[
\tan \theta = \frac y x \implies \theta = \tan ^{-1} \left(\frac {4}{3}\right)
\]

Answer 12

\(\huge o.O\)

Answer 13

Does algebra have a wee wee or a coochie?

Answer 14

We can start with a graph for this one, with arrows representing the two velocities...
3m/s west and 4m/s south
