Answer:
Step-by-step explanation:
y2-y1/x2-x1
0+7/-1-9
7/-10=m
y-0=-7/10(x+1)
The mean would be the best way to summarize her answer because mean is the average.
Answer:
the average rate of change is 2 with an intercept of 5
Step-by-step explanation:
B is the true statement. This is because when something has a larger number in a negative since ( -6.6 ) that doesn't mean it's greater than ( -5.8 ). It's less than -5.8, because -5.8 is closer to a positive number. Refer to a number line for a visual exampole :)
Answer:
The rate at which the temperature is changing at 4 p.m. is
Step-by-step explanation:
The derivative, is the instantaneous rate of change of with respect to when .
We know that the daily temperature in degrees Fahrenheit of Phoenix in the summer can be modeled by the function
,
where is hours after midnight.
To find the rate at which the temperature is changing at 4 p.m. First, we must find the derivative of this function.
So,
Then, at 4 p.m means because is hours after midnight.
Thus,
The rate at which the temperature is changing at 4 p.m. is
