ser-zykov [4K]

Answer:

55%

Step-by-step explanation:

We have to divide the new price by the original price

4500/2900 = ca. 1.5517

Take away 100% from this answer and we get 0.5517 over the original price

This is the same as 55.17% can be rounded to 55%

What is the simplified form of (2x^1/2y^2/3)(4x^1/4y^5/6).

Zielflug [23.3K]

Answer:

The simplified form is: $\frac{1}{2}x^{\frac{1}{4}}y^{-\frac{1}{6}}$ or $\frac{x^{\frac{1}{4}}}{2y^{\frac{1}{6}}}$

Step-by-step explanation:

So we need to find the simplified form of:

$\frac{2x^{\frac{1}{2}}y^{\frac{2}{3}}}{4x^{\frac{1}{4}}y^{\frac{5}{6}}}$

We know that:

(a^m)/(a^n) = a^(m-n)

Then:

$\frac{2}{4}x^{\frac{1}{2} - \frac{1}{4} }y^{\frac{2}{3}-\frac{5}{6}}$

Simplifien the expression:

$\frac{1}{2}x^{\frac{1}{4}}y^{-\frac{1}{6}}$

So, the simplified form is:

$\frac{1}{2}x^{\frac{1}{4}}y^{-\frac{1}{6}}$ or $\frac{x^{\frac{1}{4}}}{2y^{\frac{1}{6}}}$

Help urgent calcus question

KatRina [158]

Answer:

Step-by-step explanation:

The awnser must be c, since you can only get a quadratic polynomial function if you derive a polinomial of the 4th degree twice. C is the only polynomial of the 4th degree here, the other ones are of the 3rd degree.
