The average rate of change from day 2 to day 10 is -0.75 houses per day
Step-by-step explanation:
To solve this problem, we should know that have been given a non-linear curve.
The average rate of change for a linear curve is the slope of the line joining the two points.
In this case, a tangent line touching both points would be used on the curve.
We draw a line joining the curve at day 2 and day 10 and we can estimate the slope.
Average rate of change =
Change in y is the function of change in the number of households between day 2 and day 10
Change in x is a function of changes in the number of days.
The coordinate of the tangent:
at day 2: (2,8)
at day 10: (10,2)
Average rate of change =
y₂ = 2
y₁ = 8
x₂ = 10
x₁ = 2
Average rate of change = = - houses per day.

<u>QUESTION 1</u>
Let represent the number of years.
Then each year the number of people added is given by the function
Therefore after years,
In scientific notation,
<u>ANSWER TO QUESTION 2</u>
The population after 25 years can be calculated by adding the increment in population to the initial population.
The initial population
The population after 25 years
Combine like exponents, so we have 10g^3 + 2g^2 + 17g -14.
Are A and B the same? Because it's one of those two.
Answer:
$37
Step-by-step explanation:
They have $260 and 7 days in a week which is spent and even amount everyday. Meaning we would divide 260 by 7. Therefore, your answer would be 37.14 meaning they could only spend the most of $37 a day.
