a city has two water towers. one tower holds 7.35 x 10^5 gallons of water and the other tower holds 9.78 x 10^5 gallons of water. what is the combined water capacity of the two towers?
a) 1.713 x 10^6
b) 1.713 x 10^5
c) 1.713 x 10^4
d) 17.13 x 10^6

c.

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)
