Let's solve ~
If it passes through x, then let's find x when y = 0
So, required values of x are 3 and -2
Now, let's differentiate the equation to get slope slope for tangent ~
Now, plug in the values of x to find slopes of tangents
and
We know, tangent are normal are perpendicular. so let's find out slopes of normals m1' and m2'
and
Now, write the equations of normals using point slope form :
Normal 1 : passing through (3 , 0), and slope = -1/5
and
Normal 2 : passing through (-2 , 0), and slope = 1/5
That's all for Aunty ~ hope it helps !
Given that x is the number of cars, $1700 per car => 1700x
Now you have to add the base salary, which is assumed to be the same $25000
The the total salary is $25000 + 1700x
That is the option C: S = 1700x + 25000
Answer:
probably 4 times since it is not 100% accurate I guess
