1/2 and 9 is rational but 4 is not

Step-by-step explanation:

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.

Suppose that the second term of a geometric sequence is 4 and the sixth term is 16. Find the fourth term

Kaylis [27]

Answer:

Step-by-step explanation:

<h3>Given GP</h3>

a₂ = 4,
a₆ = 16

a₄ = ?

<h3>Solution</h3>

a₂ = ar = 4
a₆= ar⁵ = 16

<u>Substitute ar in the second equation</u>

ar⁵= 16
4r⁴ = 16
r⁴ = 4
r = √2

<u>Then finding a₄</u>

a₄ = a₂*r² = 4*(√2)² = 4*2= 8

10 is 8% of a, and 5 is 4% of b. c equals b/a. What is the value of c?? step by step explanation pls...

klio [65]

Answer:

c = 1

Step-by-step explanation:

"10 is 8% of a": 0.08a = 10, or <u>a = (10/0.08)</u>

"5 is 4% of b": 0.04b = 5, or <u>b = (5/0.04)</u>

"c equals b/a": c = (b/a)

----

What is the value of c?

c = (b/a)

c = ((5/0.04)/(10/0.08))

c = (5/0.04)*(0.08/10)

c = (5/10)*(0.08/0.04)

c = (1/2)*(2)
