When Luke left his house in the morning, his cell phone battery was partially
charged. The charge remaining in Luke's battery, as a percentage, can be modeled by
the function B(t) = 54 – 4.5t, where t is the number of hours since Luke left his
house. What is the x-intercept of the function and what is its interpretation in the
context of the problem?

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

sss find all sides

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)
