Suppose you want to show the data in a circle graph. find the measure of the central angle for 7th grade. round your answer to the nearest degree, if necessary.
grade number of students
4th 45
5th 25
6th 60
7th 50
8th 60
9th 45

The sum of angle in a circle = 360 degree

The total grade number of students = 45+25+60+50+60+45 = 285

The measure of the central angle for each student = (360/285) x 1 = 1.26 degree

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
