Okay so student 2 is correct
Student one is wrong because
The student didn’t multiply by correctly
And student 3 -5(-2) its +10 not -10
Let the two required numbers be x and 100 - x, then
Sum of its squares is given by S = x^2 + (100 - x)^2
For the sum of the squares to be minimum, dS/dx = 0
dS/dx = 2x - 2(100 - x) = 0
2x - 200 + 2x = 0
4x = 200
x = 50.
The two numbers is 50 and 50.
Answer: 2.88/1
Step-by-step explanation:
Answer:
h = 4 cm
Step-by-step explanation:
refer to attached
Volume of a regular cylinder is given by
V = πr²h where r is the base radius and h = height
it is given that r = 3 cm and V = 36π cm³
hence
V = πr²h
36π = π (3²) h
h = 36π / (9π)
h = 4
