4. during december, an electronics
store saw a 27% increase in video
game sales. if the store sold an
average of $47,300 in video games
during every other month, how
much more money did it earn in
december for video game sales?
a $12,771
b $34,529
c $47,327
d $60,071

27% is the same as 0.27. So you would do 47300 x 0.27 which is 12771. Then add this to 47300. Yoir answer is 60071. (D)

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:
