Answer: -1/2
Step-by-step explanation: to find slope, use the equation (y2-y1) / (x2-x1)
(-6 - -3) / (7 - 1)
-3 / 6
= -1/2
Answer:
See below
Step-by-step explanation:
IN a right triangle , remember S-O-H-C-A-H-T-O-A <===memorize this!
sin z = O/H = opposite side/hypotenuse = 16/20
cos z = A/H = adjacent / hy[potenuse = 12/20
tan z = O/A = 16/12
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
Answer:
Step-by-step explanation:
9/16=.5625
Round that to the nearest whole number would be 1
Josh is incorrect, he did not examine the expression correctly, therefore his answer was wrong.
