an object undergoes an acceleration of 8 metre per second square starting from rest find the distance travelled in one second

4m

Step-by-step explanation:

Initial velocity (u) = 0,

Uniform acceleration (a) = 8 m/s²

Time (t) = 1 s

Distance travelled in 1 second

= ut + 1/2at²

= 0 + 1/2× 8 ×1²

= 4 m  Ans.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
