Answer:
(√2 − √6) / 4
Step-by-step explanation:
Rewrite using special angles.
sin(-11π/12)
sin((4−15)π/12)
sin(4π/12 − 15π/12)
sin(π/3 − 5π/4)
Use angle difference formula:
sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)
Evaluate:
(√3/2) (-√2/2) − (-√2/2) (1/2)
-√6/4 + √2/4
(√2 − √6) / 4
Answer:
Y= 2x+3
Step-by-step explanation:
The Slope-Intercept formula is y=mx+b. M is the slope, b is the y intercept, x is the independent variable and y is the dependent variable. In order to write an equation for these types of problems, plug in the numbers for the variables.
