Answer:
Step-by-step explanation:
169 needs to be into four parts, by which 2 sides multiply to 169. The sides would be 13 each, that way 13×13=169. You would then subtract 6m from the 13m, which gives you 7 as your answer!
Answer: 7m
Exam + Tests + Quizzes + HW + Projects = 90
Exam = 10% * grade (x) = 0.1 * x
Tests = 50% * 85 = 0.5 * 85 = 42.5
Quizzes = 15% * 95 = 0.15 * 95 = 14.25
HW = 15% * 98 = 0.15 * 98 = 14.7
Projects = 10% * 92 = 0.1 * 92 = 9.2
Exam + Tests + Quizzes + HW + Projects = 90
(0.1 * x) + 42.5 + 14.25 + 14.7 + 9.2 = 90
(0.1 * x) + 80.65 = 90 (subtract 80.65 from each side)
(0.1 * x) = 9.35 (divide 0.1 from each side)
(0.1 * x)/0.1 = 9.35/0.1
x = 0.935
The answer is 93.5%
If you don't know the first derivative of 
, but you do for 
and 
, you can derive the former via the quotient rule:
or if you know the derivative of 
:
As for the second derivative, you can use the power/chain rules:
or if you don't know the derivative of 
,
which is the same as the previous result since
