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:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
