Answer:

$45927/4096$

Step-by-step explanation:

Given is the geometric series, because the ratio of consecutive terms is common:

$r = 84/112 = 63/84 = 3/4$

The first term is 112.

So the nth term is:

$t_n = t_1*r^{n-1}$

The 9th term is:

$t_9 = 112*(3/4)^8=45927/4096$

A particle travels along the x-axis such that its position at time t is given by the function x(t)= 2t^2+t. What is the average

Lapatulllka [165]

Answer:

4: A

Step-by-step explanation:

Mathematically, the average speed over a particular range will be;

f’(b)-f’(a)/(a-b)

In this case; a = 2 and b = 10

So we have the following;

f’(x) = 4t + 1

f’(10) = 4(10) + 1 = 41

f’(2) = 4(2) + 1 = 9

So we have the average speed change as;

(41-9)/(10-2)

= 32/8 = 4
