Answer:

1/4

Step-by-step explanation:

The common ratio in a geometric sequence is the number you multiply to previous term to get the term after.

Dividing by a number is the same as multiplying by that 1/number.

So the common ratio here is 1/4.

This is a geometric sequence since you are able to find all the terms in this sequence by multiplying 1/4 to it's previous term.

Examples:

160(1/4)=40

40(1/4)=10

10(1/4)=10/4=2.5

2.5(1/4)=2.5/4=0.625.

strojnjashka [21]

Answer:

x = 0

Step-by-step explanation:

${2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {9}^{x } } \\ \\ {2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {( {3}^{2}) }^{x } } \\ \\ {2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {({3)}^{2x}}}\\ \\ {2}^{x} - \cancel{{3}^{x}} = \sqrt{ {6}^{x} } - \cancel{ {3}^{x} } \\ \\ {2}^{x} = \sqrt{ {6}^{x} } \\ squaring \: both \: sides \\ \\ {( {2}^{x} )}^{2} = {(\sqrt{ {6}^{x} })}^{2} \\ \\ {2}^{2x} = {6}^{x} \\ \\ {2}^{2x} = {(2 \times 3)}^{x} \\ \\ {2}^{2x} = {2 ^{x} \times 3}^{x} \\ \\ \frac{ {2}^{2x} }{ {2}^{x} } = 3^{x} \\ \\ {2}^{2x - x} = {3}^{x} \\ \\ {2}^{x} = {3}^{x} \\ \\ \frac{ {2}^{x} }{ {3}^{x} } = 1 \\ \\ \bigg( \frac{2}{3} \bigg)^{x} = 1 \\ \\ \implies \: x = 0 \\ \\ \because \: for \: x = 0 \\ \\ \bigg( \frac{2}{3} \bigg)^{0} = 1$

The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate thei

jolli1 [7]

Velocity=distance/time

v=d/t

So in this case:

v=(3mi/5)/(3hr/8) that's the equation you need to solve.

v=(3m/5)*(8/3hr)

8/5 mph=(3m/5)*(8/3hr)

1 3/5 mph= (3/5)/(3/8)

So the first statement is correct.

When 'x' and 'y' are in direct proportion , then the relation between 'x' and 'y' is __________

Bess [88]

Step-by-step explanation:

If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.
