What is the discriminant: 2x^2 + 3x + 10=0

ohaa [14]

The discriminant of a quadratic equation is:

$b^2-4ac$

Plug in the values.

$3^2-4(2)(10)$

$=9-80$

$=-71$

Since the discriminant is negative, you can tell that the quadratic has no real solutions.

Hope that helped!

All you need to do is multiply the different types of each choice.

For salad, there are three different items. For entree, there are four different items. For side dish, there are three different items. for dessert, there are three different items.

Multiply the four numbers:

You work 40 hours/week for 52 weeks and are given the option to be paid hourly or to go on salary. In which situation will you e

Kay [80]

Answer:

The best possible answer is A) $17.00 and hour with a $1,000 bonus.

Step-by-step explanation:

You can start by narrowing down the answers to the ones with the bonuses. The others are obviously less as it is the same pay without added bonus. Next we can determine the amount in answer A by multiplying the amount per hour by the number of hours in a week and by the number of weeks in a year.

$17.00 * 40 * 52 = $35,360

And then you add the $1,000 bonus.

Answer A Amount = $36,360

Now to find answer D amount, we multiply the total by the 10% bonus to find the bonus amount.

$32,000 * 10% = $3,200

Now we add that to the previous salary to get the overall D answer amount.

$32,000 + $3,200 = $35,200

As you can see, the amount in answer A is the larger amount.
