Answer:

The real zeros of f(x) are x = 0.3 and x = -3.3.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this problem, we have that:

$f(x) = x^{2} + 3x - 1$

So

$a = 1, b = 3, c = -1$

$\bigtriangleup = 3^{2} - 4*1*(-1) = 13$

$x_{1} = \frac{-3 + \sqrt{13}}{2*1} = 0.3$

$x_{2} = \frac{-3 - \sqrt{13}}{2*1} = -3.3$

The real zeros of f(x) are x = 0.3 and x = -3.3.

What is the volume of a cube with a side length of 3t^5units?<br>Cube V = s^3

balandron [24]

Answer:

$V=27t^{15}\ units^3$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=s^{3}$

where

s is the side length of the cube

we have

$s=3t^5\ units$

substitute in the formula

$V=(3t^5)^{3}$

$V=(3^3)(t^5)^{3}$

Remember the power rule

$(a^m)^n=a^{m*n}$ ----> multiply the exponents

so

$V=(3^3)(t^{5*3})=27t^{15}\ units^3$
