For the following set of variables, find all the relevant second derivatives. In all cases, find general expressions for the second derivatives and then substitute variables at the last step. f (x comma y )equals 3 x squared y, where x equals 2 s plus t and y equals 2 s minus 2 t f Subscript ssequals nothing (Type an expression using s and t as the variables.)

i’ll just s take the points thxs

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

i think the answer is b x = 1, y = 35/2

150
