PLEASE HELPP!! Part A:
k(x) = (g(x)+1) * (f(x)-2) write the equation of the tangent line for k|x| at x=4

Part B:
h(x)=f(x)+x^2/4x-g(x), find h’(3)

step-by-step explanation: hi!

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)
