Answer:

the common ratio is, 2

Step-by-step explanation:

Common ratio for geometric sequences states that the ratio of a term to the previous term.

It is represented by r

Given the sequence:

0.45, 0.9, 1.8, ...

This is a geometric sequence with first term 0.45

Common ration(r) = 2

Since;

\frac{0.9}{0.45} = 2,

\frac{1.8}{0.9} = 2 and so on

therefore, the common ratio is, 2

0.45 times what=0.90?
seems to be 2
for
a_n and a_{n+1}, (1 term and the next)
common ratio=\frac{a_n}{a_{n+1}}
0.45 and 0.9
0.9/0.45=2
common ratio is 2

Ryann planned on swimming 14 miles. Instead, he was only able to swim 1/4 of that distance. How many miles did Ryan swim?
mote1985 [20]

Hey there,

Given the question it shows that Ryann swam 1/4 of 14 miles that he was supposed to swim.

In words of is another way to say 1/4 * 14...

  • 14/4

This expressed as a mixed number would be...

  • 3 and 2/4 or 3 1/2

Of the 14 miles that Ryann was supposed to swim he swam 3 1/2 miles.

Hope I helped,

Amna

If f(x) = x3 and g(x) = (x + 1)3, which is the graph of g(x)?
ale4655 [162]
As you can see below, in red is <span>g(x) = (x + 1)^3 and in blue is f(x)=x^3. Adding 1 to x moves the graph to the left by 1. 

Hope this was the answer you were looking for and I hope you have a great day!
