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:
Graphed in the wrong place... the equation says the y-intercept is at -24 but there is no intercept drawn!!!!!!
Step-by-step explanation:
Answer:
y^2-y^1 over x^2-x^1 is slope intercept form
Answer:
Again, the answer is (1,-2)
Step-by-step explanation:
Substitute the values
