The last series, 6+2+6/9+6/27+..., converges.
A series converges is r<1; in the first series r=1; in the second, r=2; in the third, r=2; and in the last, r=1/3.
It's exponential. And you will triple the size every 60 minutes in 240 minutes, so triples 4 times. 2000 times 3 is 6000. 6000 times 3 is 18000. 18000 times 3 is 54000. 54000 times 3 is 162000 so D is the answer.
Answer:
a. 19
Step-by-step explanation:
5/6x-1/5x=19
5/6(30)-1/5(30)=19
25-6=19
19=19
?/30(30)=19
19/30(30)=19
19=19
I'm not sure if this is exactly what you're looking for, but 19=19 if you plug in 19 for the box (and x=30 because of the first section, I'm guessing)
Answer:
42
Step-by-step explanation:
add both bases together and divide by 2 and multiply by height
so= 1+6/2 x 12
Since the polys are similar, the following equation of ratios is true:
7/8 = x/3. Cross multiplying produces 21=8x, and so x = 21/8 (answer)
