PLEASE HELP QUICK! (01.05 MC)The temperature of a city changed by −15 degrees Celsius over a 5-week period. The temperature changed by the same amount each week. Part A: Write an expression to show the average change in the temperature of the city each week. (5 points) Part B: Simplify the expression and explain, using words, what your answer means. (5 points)

Part A):

Part B):

Every week the temperature change of the city is equal to .

Step-by-step explanation:

Given that:

Change in temperature of a city =

Time period of the change = 5 weeks

To find:

Part A): Expression to show the average change in the temperature of the city each week.

Part B): Simplification of the expression and explanation in words about the meaning of answer.

Solution:

Here, we given the change in temperature of a city over the time period of 5 weeks.

Part A): We are given that the temperature change is constant in each week i.e. every week the temperature change is same.

Therefore, the average change in every week's temperature can be found by dividing the total change over the time period with the time period.

Expression to show the average change in temperature each week:

Part B): The simplification of the above expression gives us:

.

It means that every week the temperature change of the city is equal to .

because its not ur topic and its not for is for homework not that.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
