7 0

Answer:

Option B

Step-by-step explanation:

we know that

A <u>rational number</u> is one that can be represented as the ratio of two whole numbers

so

\frac{\sqrt{5}}{8} -----> Is not a rational number, because √5 is not a whole number, is a irrational number

\frac{\sqrt{4}}{9}=\frac{2}{9} ---> Is a rational number, because can be represented as the ratio of two whole numbers

therefore

√5/8 is irrational and √4/9 is rational

erma4kov [3.2K]

Answer:

125 meters

Step-by-step explanation:

Let distance = d and time is t

Using the variation;

d = k t^2

So let’s us get k

80 = k * 4*2

16k = 80

k = 80/16 = 5

So for 5 seconds, the distance would be;

d = 5 * 5^2

d = 125 meters
