In a time of seconds, a particle moves a distance of meters from its starting point, where .

(a) Find the average velocity between and if: (i) (ii) (iii) Enter the exact answers.

(i) When , the average velocity between and is m/sec.
(ii) When , the average velocity between and is m/sec.
(iii) When , the average velocity between and is m/sec.

(b) Use your answers to part (a) to estimate the instantaneous velocity of the particle at time . Round your estimate to the nearest integer. The instantaneous velocity appears to be m/sec.

a) (i) When h=0.1, the average velocity between and is 12.6 m/sec.

(ii) When h=0.01, the average velocity between and is 12.06 m/sec.

(iii) When h=0.001, the average velocity between and is 12.006 m/sec.

b) The instantaneous velocity appears to be 12 m/sec.

Step-by-step explanation:

The question is incomplete:

In a time of t seconds, a particle moves a distance of S meters from its starting point, where S=6t^2+4.

(a) Find the average velocity between t=1 and t=1+h if: (i) h=0.1 (ii) h=0.01 (iii) h=0.001. Enter the exact answers.

(b) Use your answers to part (a) to estimate the instantaneous velocity of the particle at time t=1. Round your estimate to the nearest integer.

The average velocity can be expressed as:

For h=0.1:

For h=0.01

For h=0.001

b) As the h becomes close to zero, the average velocity tends to v=12 m/s

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
