Answer:
40
Step-by-step explanation: Total distance = 60 miles
Total time = 30 / 30 + 30/60 = 3/2
Avg. speed = 40.
Descending order for a polynomial means from highest value of exponent to the lowest value of exponent.
If you observe the options you can see that polynomial shown in option A is only listed in descending order i.e. starting from a maximum exponent of x and then moving towards lower exponents of x.
So answer to this question is option A
Point A. (1,6)
point B.(7,8)
point C (6,3)
Circumference = 2 pi r
11304 = 2 x 22/7 x r
11304 x 7/2x22 =r = 1798.36
