If the arena charges 6.50 to park in satellite parking and 10.00 to park in an arena lot how much will be made from parking 1200

LUCKY_DIMON [66]

Answer:

$142,750

Step-by-step explanation:

To find how much money will be made we have to multiply the cost to park in a parking lot by the number of cars in that parking lot.

To find the amount made from satellite parking:

6.50 * 3,500 = 22,750

$22,750 is the amount made from cars parked in the satellite lot.

To find the amount made from the arena lot:

10.00 * 12,000 = 120,000

$120,000 were made from cars parked in the arena lot.

To find the total amount of how much was made, add the two amounts together.

22,750 + 120,000 = 142,750

In total, $142,750 was made.

What are the solutions of x^2-3x+3=0

deff fn [24]

The solutions to quadratic equation are:

$x = \frac{3 + i \sqrt{3}}{2}\\\\x = \frac{3 - i \sqrt{3}}{2}$

Solution:

Given is:

$x^2 - 3x + 3 = 0$

We have to find the solutions to quadratic equation

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\mathrm{For\:}\quad a=1,\:b=-3,\:c=3:\\\\x=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:1\cdot \:3}}{2\cdot \:1}$

$x=\frac{3 \pm \sqrt{\left(-3\right)^2-4\cdot \:1\cdot \:3}}{2\cdot \:1}\\\\x = \frac{3 \pm \sqrt{-3}}{2}\\\\x = \frac{3 \pm i \sqrt{3}}{2}$

We have two solutions :

$x = \frac{3 + i \sqrt{3}}{2}\\\\x = \frac{3 - i \sqrt{3}}{2}$
