1-A shingle slides down a roof having a 30.0 pitch and falls off with a speed of 2.0 m/s. a. How long will it take to hit the ground?
b. Calculate the highest point reached by it.

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 answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

statement #3 on andre"s list is false.
