P=2250e^(rt)
P/2250=e^(rt)
ln(P/2250)=ln(e^(rt))
ln(P/2250)=rt
r=ln(P/2250)/t

What is the sum of the geometric sequence 3,12,48... if there are 8 terms?

s344n2d4d5 [400]

Answer:

C) 65,535

Step-by-step explanation:

You can add up the 8 terms ...

3, 12, 48, 192, 768, 3072, 12288, 49152

to find their sum is 65535.

_____

<em>Estimating</em>

Knowing the last term (49152) allows you to make the correct choice, since the sum will be more than that and less than double that.

_____

<em>Using the formula</em>

You know the formula for the sum of a geometric sequence is ...

S = a1(r^n -1)/(r -1)

where a1 is the first term (3), r is the common ratio (4), and n is the number of terms (8).

Filling in the values, you find the sum is ...

S = 3(4^8 -1)/(4-1) = 4^8 -1 = 65535

19. Amanda bought a 6-cup bag of shredded cheese for $6.89. She used 2.25 cups to make lasagna and 1.25 cups to make pizza. How

SVETLANKA909090 [29]

Answer:

2.50

Step-by-step explanation:

ok, so we start out with a 6 cup bag of cheese. But then she uses 2.25 cups to make lasgna, and 1.25 cups to make pizza. we need to see how much cheese is left after she used the cups. First lets add the 2 cups: 1.25 + 2.25. Lets first add 1 + 2 = 3, then .25 + .25 = .50. Lets now add 3, and .50, and that gives us 3.50. Now to see how much cheese is left, we must subtract 6 minus 3.50, which gives us a total of 2.50. I hope that helped!
