Hello, let's figure this one out together.

Me, myself had to write this down in the notes form to understand what I was doing.

In the fraction, multiply the 2's by 3.

1 over 2(2^3)+5.3(3)

1 over 2(2^3)+(5.3)(3)

Simplify each by step.

You end of up with a decimal.

You have a total of 0.031348.

I NEED HELP WITH PRECALC PLEASE
alisha [4.7K]

Answer: First question: D, Second question: A

Step-by-step explanation:

Note: I'm not so good at expanding so I'll just solve it :)

So this leaves either C or D

Apply the sum rule:

8-70=-62

The only one that gives a negative sum is D

For the second picture, the one you have chosen is correct

a1 = 3 and r = -5 so:

an = 3/5 * (-5)^n

Plugging in 8 for n (the first choice) we get the given term: -234,375
