If kubby has only 300g of minced beef, he should use 600g chopped tomatoes, 450ml stock, and 225ml red wine.
Reason:
300g of 400g is a 25% decrease, so all other ingredients must be multiplied by .75 to even the distribution.
Try (2y+1) over Y
not sure if that’s correct tho
I found it quicker than i thought i would! the positive x-intercept is (4,0). negative x intercept is (-
,0)
The first derivitive is the slope
a positive 1st deriviive is positive slope or increasing
a negaitve 1st derivitive is negative slope or decreasing
the 2nd derivitive tells about the concavity
a negative second derivitive means it is concave down at that point
a positive 2nd derivitive means it is concave up at that point
so
first one is false
2nd is true
3rd is false because it could possibly be a minimum as well
answer is 2nd one
