Answer:

Answer:

1. a) population of the town in 2024 = 8697

2.) the earthquake with a magnitude of 8 is a 100 times stronger than an earthquake with a magnitude of 6.

Step-by-step explanation:

1) the population of a town was, in 2016.

a) Exponential growth model is given by where t is the time in years after 2016.

Year 2016 is when t = 0.

k = growth rate constant = 1.6% = 0.016

i) therefore the population of the town in 2024

= ( to the nearest whole number)

2.) log (I M S) = magnitude of earthquake where I is the Intensity of the earthquake and S is the intensity of a standard earthquake

therefore I M S =

therefore

in the diagram, the length of S is 2/3 the length of T. If S has an area of 368 cm squared, find the perimeter of the figure.

920 cm squared. Divide S by 2 then multiply to find the value of T. If S = 368 then T = 552, 368 + 552 = 920.

senior citizens receive a 10% discount off the price of a regular dinner special at the dinner bell restaurant. if the cost for a senior citizen to purchase a featured dinner special is $12.60, find the original price of a regular dinner special.

You can do 1st $12.60 divided by 100 is 0.126 then you do 0.126x10= 1.26 then you add the special price which is $12.60 plus $1.26= $13.86 that is the original price for the dinner.
