A. 30 sixth graders
b. 12 sixth graders
c. If the school has 40 students and the total of students is 70, the number of sixth graders is x
d. 36 students
There is no difference because 4•2 and 2•4 is the same you are going to get the same answer either way
5x²+y²=3
by implicit differentiation we shall have:
10x+2yy'=0
the second derivative will be:
10+2y"=0
2y"=-10
y"=-5
5^-4 / 5^3
= 5^-1
= 1/5
