Abacteria culture initially contains 100 cells and grows at a rate proportional to its size. after an hour the population has increased to 420. (a) find an expression for the number of bacteria after t hours. p(t)

answer is attached below

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

24/56=hx^7
