For each table, determine whether it shows that x and y are proportional. If x and y are proportional, fill in the blank with a number in simplest form.

table 1
x| 9 | 11 | 73 |
y| 54 | 66 | 78 |

y is [blank] times x

table 2
x| 7 | 8 | 9 |
y| 14 | 32 | 72 |

y is [blank] times x

What is the length of the missing leg in this right triangle? 18 mm 24 mm 26 mm 32 mm

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
