Answer:

see explanation

Step-by-step explanation:

These are the terms of an arithmetic sequence

The n th term ( explicit rule ) for an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

d = 9 - 2 = 16 - 9 = 23 - 16 = 30 - 23 = 7 and a₁ = 2, hence

a_{n} = 2 + 7(n - 1) = 2 + 7n - 7 = 7n - 5

Answer:

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

<u>"A shopping receipt that totals $4.90"</u>:

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

<u>"A soccer game where the average score is 4.7"</u>:

This is also an appropriate result since it is the <em>average</em> score of a soccer game, so finding a decimal is appropriate.

<u>"A stack of 15.6 watermelons"</u>:

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

<u>"A classroom with 24 students"</u>:

This is an appropriate result since the number of students is a whole number not a decimal.

Hope this helps :)

How does g(t)=20.9t change over the interval from t=2 to t=3?
Marrrta [24]

slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ g(t)= 20.9t\qquad \begin{cases} t_1=2\\ t_2=3 \end{cases}\implies \cfrac{g(3)-g(2)}{3-2}\implies \cfrac{20.9(3)~~ - ~~20.9(2)}{1} \\\\\\ 62.7~~ - ~~41.8\implies 20.9
