Answer:

x= -2/5 and x= 3

Step-by-step explanation:

Given equation is,

5x^2 - 13x - 6 = 0

Or, 5x^2 - 15x + 2x - 6 = 0 ( using middle term method)

Or, 5x( x- 3) + 2 (x-3) = 0

Or, (x-3) (5x+2) = 0

Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.

So, x= 3 or, 5x = -2

Or, x= -2/5

So, the answer is x= -2/5 and x= 3.

1.a sphere with a radius of three units

By definition, the volume of a sphere is:
$V = ( \frac{4}{3} ) (\pi) (r ^ 3)
$
Substituting values we have:
$V=(\frac{4}{3})(\pi)(3^3)$
Rewriting we have:
$V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi$

2.a cone with a diameter of twelve units and a height of three units

By definition, the volume of a cone is given by:
$V = \frac{1}{3} (\pi) (r ^ 2) (h)
$
Substituting values we have:
$V = \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)
$
Rewriting we have:
$V = (\pi) (6 ^ 2)

V = 36\pi$
