Answer:

The number D = b2 – 4ac determined from the coefficients of the equation ax2 + bx + c = 0. The discriminant reveals what type of roots the equation has. Note: b2 – 4ac comes from the quadratic formula.

The volume of the cube below is ß cm.

Papessa [141]

Answer:

C) x = 1 / 2

Step-by-step explanation:

Formula for volume of a cube = a^3 ('a' to the power 3 or 'a' cubed)

a = side

Since volume = 1/8 ,

cube root of 1 / 8 will equal the side of the cube(which is 'x').

cube root of 1 / 8 = 1 / 2

answer = 1 / 2

What is the slope of the line that contains these points?<br> (-1,10) (0,18) (1,26) (2,34)

-BARSIC- [3]

The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) ,

(2 , 34) is 8

Step-by-step explanation:

You can find the slope of a line from any two points lie on it

The formula of the slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points lie on it

∵ A line contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34)

- To find the slope of the line chose any to points

∵ Points (0 , 18) and (1 , 26) lie on the line

∴ $x_{1}$ = 0 and $x_{2}$ = 1

∴ $y_{1}$ = 18 and $y_{2}$ = 26

- Substitute these values in the formula of the slope above

∵ $m=\frac{26-18}{1-0}$

∴ $m=\frac{8}{1}$

∴ m = 8

The slope of the line that contains these points (-1 , 10) , (0 , 18) , (1 , 26) , (2 , 34) is 8
