When it is necessary to verify observer-target distance, the flash to bang technique can be used. To estimate the distance of the impact of your artillery, or sound from the enemy explosions, etc., you must count from the flash to sound you hear. How many meters per second are used to estimate that distance?

answer: im sorry i dont get it

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the bolded word " farsighted" could be replaced with visionary.
