Hello!
The residual for the point (5,1) is
To calculate residuals, we need to calculate the value of the line of best fit in the same x coordinate as the point we want to study to know the Predicted-y-value. To do so, we make the substitution of 5 into the equation:

Now we determine the residual with the following equation:

Have a nice day!
Answer:
270 degrees
Step-by-step explanation:

Answer:
the formula for a function d(x) that describes the distance is 
Step-by-step explanation:
We are going to define final point
, and initial point
, then we can use
, so we obtain
, by developing it 
This formula describes the distance between those two points and involves x
Answer:
600 m
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m.
Since the tires revolve 15 times per second, this means every second the tires travel 15 m.
This means that in 40 seconds, the tires travel
15(40) = 600 m.
Well,properties can help you because you can shorten or make an equation more understandable, like using distributive property in the example 2(5x-3), you can rewrite it as 10x-6. See?
