For this case we expand the series for each value of "n":

125 (\frac {1} {5}) ^ {1-1} +125 (\frac {1} {5}) ^ {2-1} +125 (\frac {1} {5}) ^ {3 -1} +125 (\frac {1} {5}) ^ {4-1} =

125+ \frac {125} {5 ^ 1} + \frac {125} {5 ^ 2} + \frac {125} {5 ^ 3} =\\125+ \frac {125} {5} + \frac {125} {25} + \frac {125} {125} =\\125 + 25 + 5 + 1

So, the correct option is: A

Answer:

Option A

Melissa plans to rent a car for her 7 day vacation. The rental company charges a $99 fee for week-long rentals plus $0.20 per mi
Scorpion4ik [409]

Answer:

The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive  505 miles or less on her vacation.

Step-by-step explanation:

In order to solve this problem we can first create an equation that represents the total paid in function of the miles driven. We have:

total paid = 99 + 0.2*miles

Since Melissa can oly pay $200 for the rent, then the total paid by her must be less or equal to this value so we have:

99 + 0.2*miles <= 200

0.2*miles <= 200 - 99

0.2*miles <= 101

miles <= 101/0.2

miles <= 505 miles

The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive  505 miles or less on her vacation.

oee [108]
I think f(x) is 2x², and I think you're trying to ask for 'g' of 'f of x'.

g(x) = 3x

g [ f(x) ] = 3 (2x²) = 6x² .

That's choice-'a'.
