Answer:

See Explanation

Explanation:

The question is incomplete as the value of s(t) is missing;

However, the following explanation will guide you;

I'll continue my explanation with the following assumption that:

s(t) = 64 + 4(t-6)

Required

Determine the velocity at t = 8

To do this; first calculate s(t) by substituting 8 for t in s(t) = 64 + 4(t-6)

s(8) = 64 + 4(8- 6)

s(8) = 64 + 4(2)

s(8) = 64 + 8

s(8) = 72

Next, is to calculate the velocity by dividing s(t) by t where t = 8

i.e.

Velocity = \frac{s(t)}{t}

Substitute 8 for t

Velocity = \frac{s(8)}{8}

Substitute 72 for s(8)

Velocity = \frac{72}{8}

Velocity = 9\ ft/s

<em>So: all you need to do is first calculate s(8), then divide the resulting value by 8 to get your result</em>

How has the age of atlanta's population changed and why?
mel-nik [20]

Answer and Explanation:

The population of Atlanta grew strongly during the period from 2017 to 2019, thanks to an expansion of the technology center, revitalization of urban centers and regions that were previously undervalued, gradual investment in trade and real estate. This led to a decrease in the birth rate of the city, since people are busy in the labor market and have no plans to have children. This decrease in the birth rate has meant that the population of Atlanta has more elderly people than children, making it an aging population. In addition, the city's economic progress promotes an increase in life expectancy allowing an increase in the elderly population.

Explain ONE internal effort on the part of a government to lessen devolutionary pressures in a country.
vesna_86 [32]

Answer:

An internal effort by a government to lessen revolutionary pressures in a country could be to moderate government positions, orienting them towards positions closer to those of the revolutionaries. In this way, a change in the government's positions would be evidenced, which would be seen by the revolutionaries as an assignment in favor of them, calming the conflict as it would be perceived as the partial fulfillment of the objective by the revolutionaries.
