Geometric series is a series of numbers where the ratios of successive terms are the same. <span> To answer this problem, the information that we need to know are the first first term, the number of terms and the ratio of any successive terms. First we get the number of terms by the equation:
an= a1(r)^(n-1) solve for n, which results to 8.
Then the sum is computed by the equation:
Sn = a1(((r)^n)-1)/(r-1))
The answer is then A 1,020</span>
Step-by-step explanation:
x+2<−5
Step 1: Subtract 2 from both sides.
x+2−2<−5−2
x<−7
Answer:
x<−7
Log 2x + log 12 = 3log 2x = 3 - log 12log 2x = 3 - 1.08log 2x = 1.922x = 10^1.922x = 83.33x = 83.33/2x = 41.67
-1/3. When a line is rotated by 180 degrees, find the new slope by calculating the reciprocal (1 divided by the original number, then multiplied by -1).
