Answer:
AM = 25, AC = 15, CM = 20
Step-by-step explanation:
The given parameters are;
In ΔACM, ∠C = 90°, ⊥
, AP = 9, and PM = 16
² +
² =
²
=
+ PM = 9 + 16 = 25
= 25
² =
² +
² = 9² +
²
∴ ² = 9² +
²
Similarly we get;
² = 16² +
²
Therefore, we get;
² +
² = 9² +
² + 16² +
² =
² = 25²
2·² = 25² - (9² + 16²) = 288
² = 288/2 = 144
= √144 = 12
From ² = 9² +
², we get
= √(9² + 12²) = 15
= 15
From, ² = 16² +
², we get;
= √(16² + 12²) = 20
= 20.
Answer:
And for 0 miles if we use the model we got:
But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.
Step-by-step explanation:
For this case we assume the following data:
Miles traveled (X): 2,3,10,7,8,15,3,1,11
Sales (Y): 31,33,78,62,65,61,48,55,120
We want to found a linear model like this one : . Where:
Where:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
And for 0 miles if we use the model we got:
But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.
