Answer:

<20,23>

Step-by-step explanation:

2v = 2<0,-1> = <0,-2>

5u = 5<4,5> = <20,25>

2v + 5u = <0,-2> + <20,25>

= <20,23>

2v = 2*<0,-1> = <0,-2>

5u = 5* <4,5> = <20,25>

2v+5u = <0,-2> + <20,25>

330 + a = 360

a = 360 - 330

a = 30 degree.

The profit function for a new product is given by p(x) = -4x^2+28x-40, where x is the number sold in thousands. How many items m
Ivenika [448]
The break even point is when profit is equal to zero, or in this case when p(x)=0

4x^2-28x+40=0

4(x^2-7x+10)=0

4(x^2-2x-5x+10)=0

4(x(x-2)-5(x-2))=0

4(x-5)(x-2)=0

So the break even points are when x=2 and 5, which is when 2000 and 5000 units are sold.
