Answer:

1183

Step-by-step explanation:

Common difference:

d = 31 - 15 = 16

nth term:

$a_n = a_1 + (n - 1)d$

Here, $a_1 = -1$

$a_{75} = -1 + (75 - 1)(16)$

$a_{75} = 1183$

Answer:

The answer is

$\frac{1372}{3} \pi \: {cm}^{3}$

Step-by-step explanation:

First you have to find the radius of sphere by dividing diameter by 2 :

$radius = diameter \div 2$

Let diameter = 14,

$radius = 14 \div 2$

$radius = 7 \: cm$

Next you have to use the volume of sphere formula :

$v = \frac{4}{3} \times \pi \times {r}^{3}$

Let r = 7,

$v = \frac{4}{3} \times \pi \times {7}^{3}$

$v = \frac{4}{3} \times \pi \times 343$

$v = \frac{1372}{3} \pi \: {cm}^{3}$

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.

yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.

Step-by-step explanation:

The average rate of change of the cost of a pack ( $r$ ), in monetary units per year, is equal to the change in the average cost of a pack ( $\Delta c$ ), in monetary units, divided by the change in time ( $\Delta t$ ), in years. Then, the average rate of change is:

$r = \frac{\$\,5.31-\$\,0.88}{2000-1980}$

$r = \$\,0.22\,\frac{1}{yr}$

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.
