Which is the value of the discriminant for the quadratic equation 0=x+2+x^2​
solong [7]
0 = x + 2 + x^2
x^2 + x + 2 = 0
a = 1, b = 1, c = 2

discriminant = b^2 - 4ac = 1^2 - (4 x 1 x 2) = 1 - 8 = -7

A 20 meter ladder rests vertically against the side of a barn. A pig that has been hitched to the ladder starts to pull the base
kirill115 [55]

Answer:

I hope my drawing explains well lol... h = 16

Step-by-step explanation:

So basically first you need to find x (the one in the drawing), by doing so, you just have to use the formula,

speed =  \frac{distance}{time}

You substitute in the speed and the time given,

0.4 =  \frac{x}{30}  \\ x = 12

Then, you use the Pythagorean theorem,

h =  \sqrt{ {20}^{2}  -  {12}^{2} } \\  h = 16
