9514 1404 393
Answer:
22/21
Step-by-step explanation:
Taking the derivative, we have ...
2x·dx +2y²·dx +4xy·dy +3·dy = 0
dx(2x +2y²) +dy(4xy+3) = 0
At the given point, this is ...
dx(2·2 +2·(-3)²) +dy(4·2·(-3) +3) = 0
22dx -21dy = 0
dy/dx = 22/21
The slope of the tangent at the point of interest is 22/21.
Answer:
3/28
Step-by-step explanation:
Set them up like this:

and the 5's cancel each other out, leaving you with

Multiply straight across the top and straight across the bottom to get

When you reduce as much as possible before multiplying, the answer will automatically be in its reduced form.
Answer:
Step-by-step explanation:
1 = (20 x 70) + (70 x 20) = 1400 x 2 = 2800 squared meters
2 = 9.18 x 2 = 18.36 + 9.72 = 28.08 squared centimeters
3 = 9 x 4 = 36 + 6 + 3 = 45 squared units
