Question

Which of the following is rational A)root over 3 B)77 C)4/0 D)root over 11​

Answer 1

Answer:

distance =1/2×2×4 +1×4 +1/2×2×2=4+4+2=10m

displacement =+(1/2×2×4)+(1×4)-(1/2×2×2)

=+4+4-2=+6m

Average velocity =+6m/5s

=1.2m/s

Answer 2

Step-by-step explanation:

Solve the given expressions 

(1) 23=4.795831523

The decimal expansion is non terminating non recurring.

∴23 is a irrational number.

(2)225=15 

∴225 is a rational number.

(3) 0.3796 is the decimal expansion is terminating.

So 0.3796 is a rational number.

(4) 7.478478.=7.478 is the decimal expansion is non termination and recurring.

7.478478.. is a rational number.

(5) 1.101001000100001is the decimal expansion is non termination and non recurring. 71.101001000100001. is a irrational number.
