The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of

Rainbow [258]

Answer:

No units

Step-by-step explanation:

The cost function is given by;

$C(x)=x^2-20x+35$

To find the units manufactured at a cost of $5,560

We equate the C(x) to 5560 and solve for x.

$x^2-20x+35 = 5560$

$x^2-20x+35 - 5560 = 0$

$x^2-20x - 5525= 0$

The discriminant of this equation is negative.

That is,

$d = {( - 20)}^{2} - 4 \times 1 \times - 5560 \: < 0$

Hence the equation has no real roots.

This means no units can be produced at $5,560

Susan used 1/2 gallons of gas on Sunday and 3 5/8 gallons of gas on Monday. How many more gallons of gas did she use on Monday?

Nookie1986 [14]

Answer: 3 and 1/8 more

Step-by-step explanation:

You can start by converting to the same fraction and making the second one improper, so 29/8 and 4/8. Subtract them to find the difference and you are left with 25/8 or 3 1/8 gallons.

Solve for x.<br><br> 0.5x+78.2=287

Alona [7]

Answer:

x =417.6

Step-by-step explanation:

0.5x+78.2=287

Subtract 78.2 from each side

0.5x+78.2-78.2=287-78.2

.5x =208.8

Divide each side by .5

.5x/.5 = 280.8/.5

x =417.6
