Sketch the graph of the function: (a). f(x, y)=x² +4y? (level curve = 0, 2, 4, (b). f(x, y)=x² + y² +3 (level curve = 3, 4, 5, (c). f(x, y) = 19-x-y? (level curve = 0, 1, 2, 3)

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

they would have to work 32 hours.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

its very big question plz make it small
