Computer= $1200

You: makes $300 deposit


Computer= $900

You pay 10 percent interest and pay 4 quarterly installments.

*This means that you pay 4 times in a year. You pay once every 3 months + interest. So basically you pay will need to pay four times in one year to fully pay back your debt.

Interest-money paid regularly at a certain rate for the use of money lent, or for delaying the repayment of debt

You would pay $236.36 per every 3 months

Paying off $900 on 10% interest would mean that you pay a total of $945.45 in the time frame of a year (4 quarterly installments).

What is the Measure of angle ABE?
tia_tia [17]
If i’m seeing correctly, the cursor is covering a number for the measure of angle BCD. assuming that ABE is the same, as it looks, then it should be the number your cursor is covering.

- Find the discriminant of –3x2 - 4x +6=0.
lyudmila [28]

Answer:

Answer:

The value of discriminant is 384

There are two different real roots for the equation

Step-by-step explanation:

* Lets explain what is the discriminant

- In the quadratic equation ax² + bx + c = 0, the roots of the

 equation has three cases:

1- Two different real roots

2- One real root or two equal real roots

3- No real roots means imaginary roots

- All of these cases depend on the value of a , b , c

∵ The rule of the finding the roots is  

  x = [-b ± √(b² - 4ac)]/2a

- The effective term is b² - 4ac to tell us what is the types of

 the roots

# If the value of b² - 4ac is positive means greater than 0

∴ There are two different real roots

# If the value of b² - 4ac = 0

∴ There are two equal real roots means one real root

# If the value of b² - 4ac is negative means smaller than 0

∴ There is no real roots but the roots will be imaginary roots

∴ We use the discriminant to describe the number and type of roots

* Now lets solve the problem

∵ -3x² - 18x + 5 = 0

∴ a = -3 , b = -18 , c = 5

∵ Δ = b² - 4ac ⇒ (Δ is the discriminant symbol)

∴ Δ = (-18)² - 4(-3)(5) = 324 - (-60) = 324 + 60 = 384

∴ The value of discriminant is 384

∵ The value of discriminant greater then 0

∴ There are two different real roots for the equation
