1 answer:

6 0

2x=1

10x+2=7
subtract 2 from both sides
10x=5
divide 10 on both sides
x=1/2, 0.5, or 5/10

Use 1/2 to solve '2x'
2*(1/2)=1

Answer:

a. $\bold{45000\times \:10^7}$
b. $\bold{3500}$

Step-by-step explanation:

a. $\left(5\times \:10^3\right)\left(9\times \:10^7\right)$

$5\times 10^3 = 5000\\\\5000\times \:9\times \:10^7$

$\mathrm{Multiply\:the\:numbers:}\:5000\times \:9=45000$

$=45000\times \:10^7$

b. $\left(7\times 10^5\right)\div \left(2\times 10^2\right)$

$\left(7\times 10^5\right)\div \left(2\times 10^2\right)=\frac{7\times \:10^5}{2\times \:10^2}$

$\frac{10^5}{10^2} = 10^3$

$\frac{7\times \:10^3}{2}$

$\mathrm{Factor}\:\: 10^3 : 2^3\times5^3$

$\frac{7\times \:2^3\times \:5^3}{2}$

$\frac{2^3}{2}=2^2$

$7\times \:2^2\times \:5^3=3500$

Given a term in a geometric sequence and the common ratio find the first five terms, the explicit formula, and the recursive formula. Given two terms in a geometric sequence find the 8th term and the recursive formula. Determine if the sequence is geometric. If it is, find the common ratio.
