Answer:
1/4, -1/8, and 1/16
Step-by-step explanation:
Geometric sequence: -2, 1, -1/2, ....
Geometric sequence means there is a common ratio.
so from -2 , the next term is -2*r , and the next term is -2*r*r
-2r = 1, means r = -1/2
then next after -1/2, is 1/4,
and then... -1/8, and then 1/16
To find the length of the light pole you'll have to use the sine ratio.
sin 30 = x/43
43 (sin 30) = x
21.5 = x
Hope this helps :)
Answer:
a=0.17
b=2/9
c=1/4
Step-by-step explanation:
1/5 is equal to 0.2 and a is lower than 1/5. The only option that is lower than 1/5 is 0.17. We know that c is greater than b because it's shown on the number line. 2/9 is equal to 0.22 and 1/4 is equal to 0.25. So, 1/4 is greater than 2/9 and c is greater than b. So that would make c = 1/4, and by default 2/9 and b are the only ones left so b= 2/9.
30, ___, 19, 13.5
19 - 13.5 = 5.5
30 - 5.5 = 24.5
19 + 5.5 = 24.5
Thus, 30, 24.5, 19, 13.5.
