Mama L [17]

Answer:

C. 50

The triangles are proportional and that is why you can find the scale factor. Set up a proportion (equivalent fractions). Set the proportion up with the corresponding sides together on thee top or the bottom of the proportion.

<u>91x</u> = <u>4550</u>

91        91

Find S (2x² -4/x² )dx<br><br>​
SOVA2 [1]

Answer:

if those functions under the radical are multiplied together they can be expanded as:

I=((x1+x2)^2 - 1)*(1-(x1-x2)^2)/8

let u=x1+x2 and v=x1-x2

I = (u ^ 2–1) * (1-v ^ 2)

du = dx1 + dx2; dv = dx1-dx2;

dx1 * dx2 = (du-dx2) * (dx1-dv)

or-or-or ...

int(I)*dx1*dx2=5/2
