Nookie1986 [14]

Given:

The expression is

\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=

To find:

The simplified form of the expression.

Solution:

We have,

\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=

The expression \sqrt[3]{48} can be written as

\sqrt[3]{48}=\sqrt[3]{8\cdot 6}

\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}       [\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}]

\sqrt[3]{48}=2\cdot \sqrt[3]{6}

\sqrt[3]{48}=2\sqrt[3]{6}

Therefore, \sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}.

Which equation represents the polar form of x² + (y + 4)² = 16?
Paraphin [41]

x^2+y^2=r^2\hspace{5em}x=r\cos(\theta )\hspace{5em}y=r\sin(\theta ) \\\\[-0.35em] ~\dotfill\\\\ x^2+(y+4)^2=16\implies x^2+\stackrel{binomial~expansion}{y^2+8y+16}=16 \\\\\\ \underset{x^2+y^2}{r^2} + 8(~\underset{8y}{r\sin(\theta )}~)=16-16\implies r^2+8r\sin(\theta)=0 \\\\\\ r^2=-8r\sin(\theta )\implies \cfrac{r^2}{r}=-8\sin(\theta )\implies r=-8\sin(\theta )

Dmitrij [34]

Answer:

2.749

Step-by-step explanation:

Use the polar distance formula:

\sqrt{r_{1}^{2}+{r_{2}^{2}-2 r_{1} r_{2}cos(theta_{1} -theta_{2})

\sqrt{10^{2}+{3^{2}-2(1) (3)cos(225-(-91))

A clothing store pays $89.47 for a dress. The store’s percent of markup is 50% and the tax is 7.6%. Find the selling price for t
Goryan [66]
Hi,
<span>SP=Selling Price
</span>CP of dress= $ 89.47
percent of mark up = 50%
SP without tax= 100+ mark up % /100 * CP
<span>SP without tax= 100+50/100 * 89.47
</span>SP without tax= 150/100 * 89.47
SP without tax= 1.5 * 89.47
<span>SP without tax= $ 134.205
</span>tot. SP(SP with tax)= 100 + tax %/100 * SP
<span>SP=100 + 7.6/100 * 134.205
</span>SP= 107.6/100 * 134.205
SP= 1.076 * 134.205
<span>SP=  $144.40458
Hope this helps you.</span>
