Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 9, - 10) and (x₂, y₂ ) = (- 2, - 5)
m = = → C
So, here we have an exponential function.
Remember that an exponential function has the form:
Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that
So,
For city B:
But something different happens with city C. This is not an exponential function, this is a linear function.
So,
Answer: Slope = 3
Y-intercept = 2
Step-by-step explanation:
The formula is a formula that uses slope and Y-intercept to identify a line on a graph.
m = Slope
b = Y-intercept.
Answer:
1.8611 x 10^4 lbs per capita
Step-by-step explanation:
To calculate the per capita garbage we have to divide the amount of garbage by the number of people
garbage = 5.416 x 10^12 lbs
people = 2.91 x 10^8
5.416 x 10^12 / 2.91 x 10^8 =
To make it easier we can take the scientific notation of the first term to the same exponent the second
5.416 x 10^12 = 54,160 x 10^8
54,160 x 10^8 / 2.91 x 10^8 =
Now that we have multiplying the same in both parts of the division you can simplify both terms above and below
54,160/2.91 = 18,611
18,611 = 1.8611 x 10^4
Answer:
1,542.45
Step-by-step explanation:
Rate tax 13% => Total cost after tax is the sum of total cost before tax and cost of tax
The value of cost of tax: 1,365x13%=177.45
So, total cost: 1,365+177.45=1,542.45
