Answer:
Step-by-step explanation:
7.5xsin(16.7)/2.5=0.8620815595
sin-1(0.8620815595)=59.55110984
Answer:
0.7bar
Step-by-step explanation:
(32-18)/18
=14/18
=7/9
=0.7bar
Height and then the inches over 12.
Ex. 5'4" = 5 4/12 or 5 1/3
Given nth term of an AP = 7-4n
Put n = 1 then t1 = 7-4(1) = 7-4 = 3
Put n = 2 then t2 =7-4(2) = 7-8 = -1
Common difference = t2-t1 = -1-3 = -4
The answer is A. Working the formula backwards you get that r^2=256, so r=16
