Determine the validity of the following experiment based on the trend of the results. A. Experiment’s results lie close to the best fit line and have no noticeable outliers; it is not reliable.
B. Experiment’s results vary greatly from the best fit line; this variation means the data is reliable.
C. Experiment’s results vary greatly from the best fit line; this variation means the data is not reliable.

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

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
