Find positive numbers a and b so that the change of variables s=ax, t=by transforms the integral ∬Rdxdy into ∬T∣∣∣∂(x, y)∂(s, t)∣∣∣dsdt for the region R, the elliptical region x2/4+y2/16≤1 and the region T, the circle s2+t2=1.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
