I believe it’s -6ax - 35b + 48c, sorry if it’s wrong
It can maybe be um 3 times 17 55 um maybe 88
Answer:
The slope of tangent at point (1,-2) is
.
Step-by-step explanation:
The given equation of ellipse is

Differentiate both sides with respect to x.





Calculate the value of \frac{dy}{dx} at (1,-2).



Therefore the slope of tangent at point (1,-2) is
.
Answer:
The length of the rectangle is 13 inches and its width (13 + 12) is 25 inches.
Step-by-step explanation:
You have to consider the formula of the perimeter = 2·length + 2·width.
If we call "x" to the length ⇒ width = x + 12 .
Perimeter = 2x + 2·(x + 12) ⇒ Perimeter = 2x + 2x + 24
⇒Perimeter = 4x + 24. ⇒ 76 = 4x + 24 ⇒ 76 - 24 = 4x ⇒52 = 4x
⇒ 52/4 = x ⇒ x = 13.
So, the length of the rectangle is 13 inches and its width (13 + 12) is 25 inches.
