The discriminant for a quadratic polynomial gives you information about the polynomial's roots.

Given y=ax^2+bx+c, the discriminant is given by \Delta=b^2-4ac.

There are three possible conclusions you can draw. If \Delta>0, then the quadratic has two distinct real roots. If \Delta=0, then there is one repeated real root. If \Delta, then there are two complex (non-real) roots.

Since you found \Delta=72>0, that means that y has two distinct real roots.

What is the next two term in the sequence 6, 10, 14, 16
8090 [49]

Answer:

  • Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

  • 10 - 6 = 4

Subtract the second term form the third term:

  • 14 - 10 = 4

Subtract the third term from the Fourth term:

  • 16 - 14 = 4

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

⟶ 16 + 4 = 20

⟶ 20 + 4 = 24

Hence,

  • <u>Next two terms of the sequence is 20 and 24.</u>

A bag contains blue and yellow counters.
ale4655 [162]

Answer:

5.25 : 1

Step-by-step explanation:

If 84% of the counters are blue, then 16% of the counters are yellow.

percentage of yellow counters = 100% - 84% = 16%

blue counters : yellow counters = 84 : 16 (we don't write %)

Now divide with 16, so the second number becomes 1.

\frac{84}{16} : \frac{16}{16} = 5.25 : 1
