Answer:
Step-by-step explanation:
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. x is treat any other variable as a constant.
dz/dx=0-2x-0
dz/dx=-2x
Evaluating this at (7,-3) gives us dz/dx=-2(7)=-14.
Since this result is negative, it mrans as x increases z decreases.
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. y is treat any other variable as a constant.
dz/dx=0-0-2y
dz/dx=-2y
Evaluating this at (7,-3) gives us dz/dy=-2(-3)=6.
Since this result is positive it mrans as y increases z decreases.

Step-by-step explanation:
Randy first won 12 points on Monday. He earned as twice as many on Tuesday.
12 * 2 = 24
Randy scored 24 points Tuesday.
Randy earned 3 more points than Tuesday's points the next day.
24 + 3 = 27
Randy earned 27 points Wednesday.
12 + 24 + 27 = 63
Randy should earn a total of 63 points for the 3 days.
Hope this helps.
Answer:
124.59
Step-by-step explanation:
The third digit of right of decimal point is 6
