Find the sum of the first 10 terms for the sequence {21, 63, 189, . . . }.
antiseptic1488 [7]
The sum of n terms of a geometric sequence with first term "a" and common ratio "r" is given by
S_{n}=a\dfrac{r^{n}-1}{r-1}
You have a=21, r=3, so the sum of 10 terms is
S_{10}=21\cdot \dfrac{3^{10}-1}{3-1}=620004

The appropriate choice is the 2nd one:

LEon made 4 liters of lemonade for the party, but it was too strong, it was 14% lemon juice. How much 8% lemonade should he add
dsp73
<span>Item       Number of Liters          Percentage of LemoneA                    4        14%B                    x         8%Result           4+x            10%
For a mixture of solutions to form a resulting solution, we know
V1 * N1 + v2 * N2 = V * N
where, V1 = Volume of mixture of 1 N1 = Concentration of mixture 1V2 = Volume of mixture of 2 N2 = Concentration of mixture 2
V = volume of mixture N = Concentration of mixture
So solving we get:
(4+x)*10 = 4*14 + x * 8or, 10x-8x = 4*14-4*10or, 2x = 16or x = 8
so 8 litres of the solution B must be added to the solution<span>
