Answer:
37
Step-by-step explanation:
36-4+
32+5
37
Point-slope form is y - y1 = m (x + x1)
First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1
13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2
Plug in the first point (as instructed) into the equation.
y - (-9) = -2 (x - 9)
Simplify the beginning.
y + [9] = [-2] (x + [-9])
(The brackets are the fill in the blanks)
Answer:
20
Step-by-step explanation:
16 divided by 4/5 = 20 :)
The rule would be ~y=4x+3~

The exact value for cos(pi/16) would be :
cos (pi/16) = +/- √1+cosa/2
cos (pi/4) = sqrt2/2
