Answer:

$\cos x=\dfrac{8}{f}$

Step-by-step explanation:

Given that,

$\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}$

We need to find the value of cos x.

We know that,

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}$

Using the above relation,

$\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}$

So, the value of cos x is equal to $\dfrac{8}{f}$ .

Simplify the following: 6i^3 +4j^2 -6i<br> Please show work

Vadim26 [7]

Answer:

Concept: Vectors

I think the confusion here might be the usage of i and j
Just to let you know, i=x and j=y
So let's use that fact to conceptualize this
6x^3+4y^2-6x
We can simplify by applying a common factor
2(x^3+2y^2-3x)
Thats the most we can simplify this
