The height of a cone is equal to the diameter of the base. What expression represents the volume of the cone, in cubic units?
Maurinko [17]
By definition, the volume of a cone is given by:
 V = (1/3) * (\pi) * (r ^ 2) * (h)

 Where,
 r: radius of the circular base
 h: height of the cone
 Let's define a variable:
 x: diameter of the base
 We have then that the radio is:
 r = x / 2

 The height is:
 h = x

 Substituting values:
 V = (1/3) * (\pi) * ((x / 2) ^ 2) * (x)

 Rewriting:
 V = (1/3) * (\pi) * (x ^ 2/4) * (x)

V = (1/12) * (\pi) * (x ^ 3)
 Answer:
 
An expression that represents the volume of the cone, in cubic units is:
 
V = (1/12) * (\pi) * (x ^ 3)

Use polynomial division to completely factor y=x^3+3x^2-13x-15 by x+5
Salsk061 [2.6K]

Answer:

(x - 3)(x + 1)(x + 5)

Step-by-step explanation:

I'd use synthetic division instead.  If we were to find the roots of the given polynomial, we could from them write the factors as well.

The divisor x + 5 corresponds to root x = -5.  Setting up synthetic div.,

-5   )   1    3    -13    -15

               -5     10    +15

      -----------------------------

           1   -2     -3      0

Since the remainder is 0, we know that -5 is a root and (x + 5) is a factor.  Moreover, we know that the coefficients of the quotient are 1, -2 and -3.

1x² - 2x - 3 can be factored:  the factors are (x - 3) and (x + 1).

So the end result for this problem is (x - 3)(x + 1)(x + 5).
