Answer:

$a_{n}$ = 6 $(5)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

$a_{n}$ = 6 $(5)^{n-1}$

1. 10(.15)=1.5

Fed [463]

Answer:

6.14125(0.15) = 0.9211875 (below 1)

6.14125 - 0.92118 = 5.22007

Step-by-step explanation:

Given data

1. 10(.15)=1.5

2. 10-1.5=8.5

3. 8.5 (.15)=1.275

4. 8.5-1.275=7.225

continuation the sequence

5) 7.225 (0.15) = 1.08375

6) 7.225 - 1.08375 = 6.14125

7) <u> 6.14125(0.15) = 0.9211875 (below -one)</u>

8 ) <u> 6.14125 - 0.9211875 = 5.2200625 (get number 5)</u>

9) 5.2200625(0.15) = 0.783009

10) 5.2200625 - 0.783009 = 4.4370532

Find the distance between the points (7,23) and (3,-3), rounded to the hundredths place

Molodets [167]

Answer:

26.31

Step-by-step explanation:

Use distance formula

d = $\sqrt{(x_{2}-x_{1)^{2} + (y_{2}-y_ ^{1)^2} } }$

substitute in points and solve

d = $\sqrt{(7-3)^2 + (23-(-3))^{2} }$

d = $\sqrt{4^{2}+26^{2} }$

d = $\sqrt{16 + 676}$

d = $\sqrt{692}$

d = 26.30589288

d = 26.31 rounded
