Answer: They led to larger urban cores that used professional armies to increase their territory and enslave people.
Explanation:
Trade generally brings about wealth and this was the case for West African societies as a result of interactions with the Muslim traders who crossed the Sahara to trade with them.
As a result of the gains from trade, wealthy urban cores and cities were formed such as Timbuktu, Gao and Agadez
. The wealth the rulers of these cities acquired enabled them to use professional armies to conquer more territory.
Indeed one of the richest men in history, Mansa Musa ruled over an empire that became so rich due to trade in his territory.
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

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:

Required
Determine the velocity at t = 8
To do this; first calculate s(t) by substituting 8 for t in 




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

Substitute 8 for t

Substitute 72 for s(8)


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