Answer the linear inequality
PolarNik [594]
Substitute x-values into x.
e.g. y>-3.5x + 2
let x be 1...
thus, y>-3.5(1) + 2
y> -1.5 or y<1.5
another e.g. let x be 2.
y> -3.5(2) + 2
y> -4.4 or y<4.4
And so forth. pluck in these coordinates into you graph and sketch a line through the points.
NOTE: < in my explanation is equivalent to less than or equal to. same goes to >… greater than or equal to.

I hope you followed through. Good luck!

Find the exact value of sin 105 degrees​
STALIN [3.7K]

Answer:

\frac{\sqrt{6}+\sqrt{2}}{4}

Step-by-step explanation:

I'm going to write 105 as a sum of numbers on the unit circle.

If I do that, I must use the sum identity for sine.

\sin(105)=\sin(60+45)

\sin(60)\cos(45)+\sin(45)\cos(60)

Plug in the values for sin(60),cos(45), sin(45),cos(60)

\frac{\sqrt{3}}{2}\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}\frac{1}{2}

\frac{\sqrt{3}\sqrt{2}+\sqrt{2}}{4}

\frac{\sqrt{6}+\sqrt{2}}{4}
