Awatering can dispenses water at a rate of 0.40 gallon per minute. the original volume of water in the can was 10 gallons. which set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water? (1 point)

{(10, 1), (9.60, 2), (9.20, 3)}

{(1, 10), (2, 9.60), (3, 9.20)}

{(9.60, 1), (9.20, 2), (8.80, 3)}

{(1, 9.60), (2, 9.20), (3, 8.80)}

Plz me plz i will give a brain just plz

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

In a two-digit number the units' digit is 7 more than the tens' digit. the number with digits reversed is three times as large as the sum of the original number and the two digits. find the number.
