What is the sum of the first 12 terms of the geometric series below 1/2+2+8+32+
Georgia [21]

∴\frac{1}{2} +2+8+32.......12^{th}term =2796202.5

Step-by-step explanation:

First term(a) = \frac{1}{2}   common ratio(r)     =\frac{2}{\frac{1}{2} }   =4

n= 12

S_{n}=\frac{a(r^n-1)}{(r-1)}

S_{12}=\frac{\frac{1}{2}(4^{12}-1) }{4-1} =2796202.5

∴\frac{1}{2} +2+8+32.......12^{th}term =2796202.5

For this problem, for finding the slope, I need help with this.
Elena-2011 [213]

Answer: the slope is 1

Step-by-step explanation:

Slope = Rise over Run. Rise= y run= x

For this problem the rise is the difference between 3 and 1 and the run is the difference between 0 and -2. The difference between 3 and 1 is 2 and the difference between 0 and -2 is also too. Which makes it 2/2 which simplifies to 1.

Mama L [17]

Option E

The numerator of fraction is 21

<h3><u>Solution:</u></h3>

2\frac{5}{8} is to be written as improper fraction in lowest terms

To find: numerator of fraction

An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number).

<em><u>To convert a mixed fraction to an improper fraction, follow these steps:</u></em>

  • Multiply the whole number part by the fraction's denominator.
  • Add that to the numerator.
  • Then write the result on top of the denominator.

2\frac{5}{8} = \frac{8 \times 2 + 5}{8} = \frac{16 + 5}{8} = \frac{21}{8}

Thus the numerator of fraction is 21. Option E is correct
