Answer:
-1/4 if you prefer the answer written as a fraction.
-0.25 is you prefer the answer written as a decimal.
Step-by-step explanation:
Common ratio of a geometric sequence can be found by doing term divided by previous term.
That is you could do:
80/-320
or
-20/80
or
5/-20
If all these ratios are not equal, it isn't a geometric sequence and does not have a common ratio.
Let's see what these reduce to:
80/-320=1/-4 =-1/4 or -0.25
-20/80=-1/4 or -0.25
5/-20=1/-4=-1/4 or -0.25
So the common ratio is -0.25 or yo you can write it as -1/4.
10 1/4 / 151 3/16 = 4/59
Have a great day :)
Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576
A) (18,576)
576 dollars made with 18 members is the highest amount made in one day.
B) (12,0) (6,0)
