Sin < C =  63/65    so m < C =  75.75 degrees

and tan B = 16/63  so m <B =  14.25 degrees

m < C + m<B = 75.75 + 14.25  = 90 degrees

Therefore m < A   = 180-90 = 90


therefore the triangle is right-angled.

Answer:

  a) 1/2

  b) 1/2

Step-by-step explanation:

a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...

  m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2

The average rate of change on the interval [2, 8] is 1/2.

__

b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.
