Find all zeros of ƒ(x) = 2x^4 – 72x^2. Then determine the multiplicity at each zero. State whether the graph will touch or cross

AleksandrR [38]

Answer: See below

Step-by-step explanation:

To find the factor,

f(x) = 0

$\begin{aligned}&2 x^{4}-72 x^{2}=0 \\&2 x^{2}\left(x^{2}-36\right)=0 \\&x^{2}\left(x^{2}-36\right)=0 \\&x \times x \times(x-6) \times(x+6)=0 \\&\mathrm{x}=0,0,6,-6\end{aligned}$

So,

x = 0 multiplicity 2

x = -6 multiplicity 1

x = 6 multiplicity 1

For an even multiplicty, the graph touches the x-axis, and for an odd multiplicty, the graph crosses the x-axis

Therefore,

x = 0 multiplicty 2, Touch

x = -6 multiplicty 1, Cross

x = 6 multiplicty 1, Cross

Can some one help me factor 6x^2+4x-10

Fudgin [204]

2(3x + 5) (x - 1)

This is done through factoring 2 out of the equation first...

2(3x^2 + 2x -5)

And then cross multiplying it

What is the volume of the box if it is scaled down by a factor of 1/10

Lina20 [59]

Answer:

12 units³

Step-by-step explanation:

original volume of box = 120 units³

If the box if it is scaled down by a factor of 1/10, then we multiply the original volume by 1/10:

120 x (1/10) = 120 ÷ 10 = 12 units³
