You are studying for your final exam of the semester. up to this point, you received 3 exam scores of 84%, 65%, and 90%. to receive a grade b in the class, you must have an average exam score between 80% and 89% for all 4 exams including the final. find the widest range of scores that you can get on the final exam in order to receive a grade of b for the class. use interval notation. a- (75,100) b-(81,100) c-(84,97)

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

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
