How do you find the slope intercept form of an equation?

Komok [63]

Answer:

The equation of line can be written as,

y = mx + c

where, m is slope

and c is intercept of line.

Now, Suppose we have equation: ax + by + c = 0

So, transforming the given equation in above standard equation.

⇒ by = -ax - c

⇒ $y = \frac{-a}{b}x +\frac{-c}{a}$

Now comparing this equation with standard equation. We get,

$m =\frac{-a}{b}$

and $c = \frac{-c}{a}$

Hence, Intercept = $c =\frac{-c}{a}$ for line ax + by + c = 0.

Find Sin 2 (30degrees)

Vinvika [58]

Answer:

Sin 2 (30)°= $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

Explanation:-

Given that Sin 2 (30)°

we know that the formula sin2θ = 2sinθ cosθ

Given that θ = 30°

Now

sin2(30)° = 2sin30° cos30°

$= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )$

After cancellation, we get

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Final answer:-

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$
