Which expression represents the series 1+5+25+125+625?

Answers

it is a geometric sequence
an=a1(r)^(n-1)
a1=first term
r=common ratio
n=which term
first term is 1
common ratio is 5
an=1(5)^(n-1)

that is the equatin/formulf for the nth term

if you want a summation formula of the sequence to the nth term
Sn=(a1(1-r^(n)))/(1-r)
in this case
Sn=(1(1-5^(n)))/(1-5) or
Sn=(1-5^(n))/(-4)
so in this case
up to 5th term

S5=(1-5^(5))/(-4)
S5=(1-3125)/(-4)
S5=(-3124)/(-4)
S5=781


anyway
a_(n)=(5)^(n-1) is the nth term
and
Sn=(1-5^(n))/(-4) is the summation up to the nth term
1(5)^0 + 1(5)^1 + 1(5)^2...

The expression representing the series would be

f(x) = 5^(x-1)

Factor the polynomial.

If both the base and height of a triangle are made nine times as long, how many times the area of the original figure is the area of the new figure?

Answers

To start: A = 1/2bh
Now by increasing both the width and height by 9, you get: A = 1/2(9b)(9h) = 1/2(81)bh

You can see that the increase in area is 81 times the original.
