Two number cubes are rolled.

aliina [53]

Answer:

1/18

Step-by-step explanation:

Assuming the die are regular 1,2,3,4,5,6

P(2) = number of 2's/ total numbers on die

= 1/6

Roll again

Assuming the die are regular 1,2,3,4,5,6

P (numbers greater than 4) = {5,6}/total numbers on die

=2/6 = 1/3

P (2, then number greater than 4) = 1/6 * 1/3 = 1/18

Find a parabola with equation y = ax2 + bx + c that has slope 5 at x = 1, slope −11 at x = −1, and passes through the point (2,

azamat

By "slope" I assume you mean slope of the tangent line to the parabola.

For any given value of x, the slope of the tangent to the parabola is equal to the derivative of y :

$y=ax^2+bx+c\implies y'=2ax+b$

The slope at x = 1 is 5:

$2a+b=5$

The slope at x = -1 is -11:

$-2a+b=-11$

We can already solve for a and b :

$\begin{cases}2a+b=5\\-2a+b=-11\end{cases}\implies 2b=-6\implies b=-3$

$2a-3=5\implies 2a=8\implies a=4$

Finally, the parabola passes through the point (2, 18); that is, the quadratic takes on a value of 18 when x = 2:

$4a+2b+c=18\implies2(2a+b)+c=10+c=18\implies c=8$

So the parabola has equation

$\boxed{y=4x^2-3x+8}$
