What is the value of r of the geometric series?

Phantasy [73]

Answer:

<h3>0.8</h3>

Step-by-step explanation:

Given the formula for the geometric series expressed as;

$\sum \left \{ {3} \atop {1}} \right 1.3(0.8)^{n-1}$

The nth term of a geometric progression is expressed as;

$T_n = ar^{n-1}\\$

a is the first term

r is the common ratio

Comparing both equations;

$0.8^{n-1} = r^{n-1}\\Cancel \ the \ powers\\0.8 = r\\r = 0.8\\$

Hence the value of r of the geometric series is 0.8

What is the completely factored form of p4 - 16?

dem82 [27]

Answer:

see explanation

Step-by-step explanation:

Given

$p^{4}$ - 16 ← difference of 2 squares and factors in general as

a² - b² = (a - b)(a + b)

$p^{4}$ - 16

= (p² )² - 4²

= (p² - 4)(p² + 4) ← (p² - 4) is also a difference of squares

= (p - 2)(p + 2)(p² + 4)
