Evaluate using suitable identity:<br>c). 98²​
Vesnalui [34]

Step-by-step explanation:

<h3><u>★ Solution :-</u></h3>

\sf \longmapsto 98^2

\sf \longmapsto (a - b)^2 = a^2 - 2ab + b^2

Here,

  • a = 100
  • b = 2

\sf \longmapsto (100 - 2)^2 = 100^2 - 2(100)(2) + 2^2

\sf \longmapsto 100^2 - 2(100)(2) + 2^2

\sf \longmapsto 10000 - 400 + 4

\sf \longmapsto 9606

Suppose the population of a town is 15,200 and is growing 2% each year. Write an equation to model the population growth. Predic
larisa [96]
For this case, what you need to know is that to model this problem, you must use equations of the potential type:
 y = A * (b) ^ t
 Where:
 A: initial population.
 b: growth rate.
 t: time.
 Substituting values we have:
 y = 15200 * (1.02) ^ t
 After 10 years we have:
 y = 15200 * (1.02) ^ 10
 y = 18529
 Answer:
 An equation to model of the population growth is:
 y = 15,200 ∙ 1.02 ^ x
 the population after 10 years is:
 about 18,529
