Angle A = (arc CD - arc BC) / 2
56 degrees = (arc CD -95) / 2
112 degrees = (arc CD -95)
arc CD = 207
Answer:
Step-by-step explanation:
Given:
The equation of the curve is:

To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,

Differentiate the given equation with respect to x.


Now we need to find the value of this derivative at (2,7).




Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
D. 6 steps forward and 6 steps backward. 6=6
