Answer:
The first term of the sequence is -120.
Step-by-step explanation:
The formula for the "nth" term of a geometric sequence is shown below:
an = a0*r^(n-1)
Where an is the nth term, r is the ratio and n is the position of the term on the sequence. For this problem we want to find what is the initial term, a0, so we will isolate it in the formula as shown below:
a0*r^(n-1) = an
a0 = an/[r^(n-1)]
We then apply the data given to us
a0 = 31.45728/[-0.8^(7-1)]
a0 = 31.45728/[-0.8^6] =31.45728 /-0.262144= -120
The first term of the sequence is -120.
Answer:
I am not certain if its right
Step-by-step explanation:
Answer:
2nd option
Step-by-step explanation:
The zeros are the points on the x- axis where the graph crosses.
Since the graph crosses the x- axis at x = - 1 and x = 5, then
The zeros are x = - 1 and x = 5
I’m pretty sure it’s it’s between f and g. Sorry if I’m not exact but hope this helps
The correct answer is the second one, I already answered it.
