Which of the following is the discriminant of the polynomial below x^2+4x+5

steposvetlana [31]

Answer:

$\huge\boxed{\sf Discriminant = -4}$

Step-by-step explanation:

Comparing it with quadratic equation $ax^2 + bx + c = 0$ , we get:

a = 1 . b = 4 and c = 5

So,

Discriminant = $b^2-4ac$

D = (4)²-4(1)(5)

D = 16 - 20

D = -4

Hence,

Discriminant = -4

$\rule[225]{225}{2}$

the highest recorded temperature in hawaii is 100 degrees F. The highest recorded temperature in colorado is 18 degrees higher t

PolarNik [594]

Answer:

The highest recorded temperature in colorado is 118 degrees F.

Step-by-step explanation:

We have to model this problem initially.

I am going to call the highest recorded temperature in Colorado x.

The highest recorded temperature in hawaii is 100 degrees F. The highest recorded temperature in colorado is 18 degrees higher than that of hawaii.

This means that x is 18 added to 100. So

$x = 100 + 18$

$x = 118$

The highest recorded temperature in colorado is 118 degrees F.
