In a survey of 80 students, 25 said they planned on attending the pep rally. the school has 550 students. predict the number of students who plan to attend the pep rally.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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:
