Calculate the double integral. (30x2y3 − 25y4) da, r = {(x, y) | 0 ≤ x ≤ 1, 0 ≤ y ≤ 1} r

-2.5

Step-by-step explanation:

We want to evaluate the double integral,

where R is the rectangular region bounded by R={(x, y) | 0 ≤ x ≤ 1, 0 ≤ y ≤ 1}

We apply the limits to obtain;

We evaluate the inner integral by integrating with respect to x whiles treating y as a constant.

This gives us,

We evaluate the resulting integral now to obtain;

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
