weeeeeb [17]

Answer:

Probability = 0.135

Step-by-step explanation:

AB¯ is the diameter of circle T. Point A is located at (-4,2) and point B is located at (2,-8). What are the coordinates of the
postnew [5]

Centre is at the middle or the midpoint of the diameter.

And the formula of midpoint is

( \frac{x_{1} +x_{2}}{2},\frac{y_{1} +y_{2}}{2})

For the given question, x1=-4, y1=2, x2=2, y2=-8

So we will get

( \frac{-4+2}{2}, \frac{2-8}{2} ) = (-1, -3)

And that's the required centre .

What is the discriminant of 3x2 - 10x = -2?<br> 76<br> 94<br> 106<br> 124
rewona [7]

Answer:

76

Step-by-step explanation:

Applying the formula to calculate the discriminant Δ=b2−4(a)(c)

Δ=b2-4(a)(c) with : a=3, b=−10, c=2

Δ=(−10)2−4⋅(3)⋅(2) = 100−24 = 76

The discriminant of the polynomial is equal to 76.
