Answer:
The value of a=6[/tex]
Step-by-step explanation:
<u>step 1:- </u>
<u>col linearity of three points :- </u>
We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,
that is three points are col linear if and only if Slope of AB= slope of BC
<u>step 2:-</u>
Since the given three points are col-linear, we have
Slope of AB= slope of BC
given points are A(2,-2) ,B(-6,2) and C(a,-4)
<u>Step 3 :-</u>
Slope of AB= slope of BC


Answer:
(2000 - 100x)(5 + x)》12000
10000 - 500x + 2000x - 100x²》12000
-100x² + 1500x + 10000》12000
x for max profit:
-200x + 1500 = 0
x = 7.5
Price = 5 + 7.5 = 12.5
Max profit:
(2000 - 100(7.5))(5 + 7.5)
= 1250 × 12.5
= $15625
7x^4 + x^3 – 3x^2 + 5x – 2
