Answer:
15. -2 16. 0 17. undefined
Step-by-step explanation:
Slope of two points can be calculated by (y change) / (x change).
(y1 - y2) / (x1 - x2)
15) (1-5) / (4-2) = -2
16) (6-6) / (1-10) = 0 since y change is 0.
17) (-5-3) / (4-4) = undefined since x change is 0 but you cannot devide by 0.
Answer:
0.8
Step-by-step explanation:
cos z = 8/10 = 0.8
N(1/5) = (2/15)
divide both sides by (1/5)
n = (2/15)/(1/5)
to divide fractions, cross multiply, e.g. (2*5)/(15*1) = 10/15
n = 10/15 = 2/3 or 0.666666.
