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:
Step-by-step explanation:
y + 4 = -8(x - 2)
I dont know the statements that u have but maybe I can guess one...or two
slope = -8
points used were : (2,-4)
y + 4 = -8(x - 2)
y + 4 = -8x + 16
y = -8x + 16 - 4
y = -8x + 12 ............slope intercept form
8x + y = 12 .......standard form
x intercept = (3/2,0)
y intercept = (0,12)
any of that answer ur question ?
It has reflectional symmetry
