I don't think it's a proportional relationship because it doesn't go the origin...im not sure,Let me know
Answer:
A. 50.24
Step-by-step explanation:
C=2πr=2·π·8=50.24
Obviously if it takes him around 12 hours to drive 1158 km. Then by ratio method we can calculate how much time it takes for him for one hour. So 1158/12 = 96.5 in one hour.
Now for the next part we can see he drove around 484 after 5 hours. So we can see his average of 1 hour by 484/5 = 96.8 so according to this pace he might arrive a little before time.
A man invests $2000 into an account that accrues 8.5% interest compounded quarterly. He made the deposit of 2 years , i.e. for 8 quarters ( or 8 compounding periods)
Amount after n years is calculated by following equation :
Amount = Principal * ( 1 + Interest rate per compounding period ) ^ no. of compounding periods
The amount in his account after 2 years = 2000 * ( 1 + 0.085/4) ^ 8
= 2000 * (1.02125 ) ^ 8
= 2000 * 1.18319
= $2366.39
That's simple
Real numbers<span> can either be </span>rational<span> or irrational. ... A </span>rational number<span> is a </span>number<span>which can be written as a ratio of two whole </span>numbers<span> (</span>integers). For example 5 is arational number<span> since 5 can be written as ratio of 5 : 1 . 5 is also an </span>integer. 2.5 is arational number<span> since it is a ratio of 5 : 2 .
Hope it helps :)</span>
