At t=0, an automobile traveling north begins to make a turn. It follows one-quarter of the arc of a circle of radius 10.7 m until at t=2.00s, it is traveling east. The speed of the car does not alter during the turn. a. What is the speed of the car?
b. What is the magnitude of the change in the car's velocity during the turn?
c. Find the magnitude of the average acceleration of the car during the turn
(showing work would be appreciated)

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
