Answer:
fractions form- x= 5/6
decimal form- x=0.83
Step-by-step explanation:
Answer:
an=1*2.5^(n-1)
=2.5^(n-1)
Step-by-step explanation:
Complete question below:
What value, written as a decimal, should Lena use as the common ratio? Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2.5), (3, 6.25).
Solution
Point (1, 1), (2, 2.5), (3, 6.25).
a=1
ar=2.5
ar^2=6.25
From ar and ar^2
r=6.25/2.5
=2.5
r=2.5
an=ar^(n-1)
Therefore, the explicit formula is
an=1*2.5^(n-1)
=2.5^(n-1)
Answer:
B is correct
Step-by-step explanation:
I think you don't need a calculator here. :) Try to figure out next time!
Yes you see 11-3 is 8 so +11-3=8
For a you would just have to add all the velocity up and divide by 5. For b its -15 the ball is going down.
