Satellites KA-121212 and SAL-111 have spotted a UFO. Scientists want to determine its distance from KA-121212 so they can later determine its size. The distance between these satellites is 900 \text{ km}900 km900, start text, space, k, m, end text. From KA-121212's perspective, the angle between the UFO and SAL-111 is 60^\circ60 ∘ 60, degrees. From SAL-111's perspective, the angle between the UFO and KA-121212 is 75^\circ75 ∘ 75, degrees. How far is the UFO from KA-121212?

where's the following? you gotta add it to know what the choices are

explanation:

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.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
