Answer:

No solution

Step-by-step explanation:

Given is the quadratic function

y = -2x² + bx - 5

In order to have two real roots the discriminant should be posivive

D = - b² - 4ac
D = - b² - 4(-2)(-5) = - b² - 40

We need D > 0

-b² - 40 > 0
b² + 40 < 0
b² < - 40

There is no solution as b² is never negative

Answer:

9n^4

Step-by-step explanation:

The divisor and quotient can be interchanged to find the divisor:

$\dfrac{18n^6+27n^5-36n^4}{2n^2+3n-4}=\boxed{\text{Blank 1}}$

Such division is carried out by first finding the quotient of the highest-degree terms:

$\dfrac{18n^6}{2n^2}=\dfrac{18}{2}n^{6-2}=9n^4$

This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...

9n^4

_____

The temperature was 38 degrees Fahrenheit before a cold front came through. Ten hours later, the temperature was -12 degrees Fah

padilas [110]

Answer:

-5 degrees per hour

Step-by-step explanation:

In 10 hours, the temperature dropped -50 degrees (38 + 12, and make it negative because the temperature went down, not up).

So divide -50 by 10

-50/10 = -5
