Find the exact value of sin(11pi/12)cos(pi/6)-cos(11pi/12)sin(pi/6)

1 answer:

6 0

We use the identity sin (A - B) = sin A cos B - cos B sin A

so the above = sin (11pi/12 - pi/6) = sin 3pi/4 = 1 / sqrt2 answer

Write an equation of the line that passes through (-1,2) with a slope of 4

Iteru [2.4K]

Step-by-step explanation:

Hey there!

Given;

The points is; (-1 , 2) and slope is 4.

Note: Use one-point formula.

$(y - y1) = m(x - x1)$

~ Put all values.

$(y - 2) = 4(x + 1)$

~ Simplify it.

$(y - 2) = 4x + 4$

$4x - y + 6 = 0$

Therefore, the required equation is; 4x-y+6=0.
