Answer:
weight of 25 students
25 × 58 = 1450kg
weight of 29 students
29 × 62 = 1798kg
total students = 25 + 29 = 54
total weight of students = 1450 + 1798 = 3248
mean weight of all students = 3248/54 = 60.19kg
First, multiply the brackets out:
(8x^4 - x + 1)(-x^5 + 5)
= -8x^9 + x^6 - x^5 + 40x^4 - 5x + 5
Then, find f'(x) by multiplying each term by the power, then reducing the power by one:
f'(x) = -72x^8 + 6x^5 - 5x^4 + 160x^3 - 5
