P³ = 1/8 please help me if anybody can .

ivanzaharov [21]

Answer:

$p= \dfrac{1}{2}$

Step-by-step explanation:

Given equation:

$p^3=\dfrac{1}{8}$

Cube root both sides:

$\implies \sqrt[3]{p^3}= \sqrt[3]{\dfrac{1}{8}}$

$\implies p= \sqrt[3]{\dfrac{1}{8}}$

$\textsf{Apply exponent rule} \quad \sqrt[n]{a}=a^{\frac{1}{n}}:$

$\implies p= \left(\dfrac{1}{8}\right)^{\frac{1}{3}}$

$\textsf{Apply exponent rule} \quad \left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}:$

$\implies p= \dfrac{1^{\frac{1}{3}}}{8^{\frac{1}{3}}}$

$\textsf{Apply exponent rule} \quad 1^a=1:$

$\implies p= \dfrac{1}{8^{\frac{1}{3}}}$

Rewrite 8 as 2³:

$\implies p= \dfrac{1}{(2^3)^{\frac{1}{3}}}$

$\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:$

$\implies p= \dfrac{1}{2^{(3 \cdot \frac{1}{3})}}$

Simplify:

$\implies p= \dfrac{1}{2^{\frac{3}{3}}}$

$\implies p= \dfrac{1}{2^{1}}$

$\implies p= \dfrac{1}{2}$

Find solutions to the equation y=−4x+1 for the x-values −1,0, and 1.

Helga [31]

Answer:

(-1, 5), (0, 1), (1, -3)

Step-by-step explanation:

y = -4x + 1

Let x = -1:

y = -4(-1) + 1 = 4 + 1 = 5

(-1, 5)

Let x = 0:

y = -4(0) + 1 = 0 + 1 = 1

(0, 1)

Let x = 1:

y = -4(1) + 1 = -4 + 1 = -3

(1, -3)

Diego bought a pair of jeans that cost $50. He turned around and sold them to a friend with a 5% markup. How much did the jeans

frez [133]

Hi there! To find the total cost after the markup, all you have to do is multiply by 105% (1.05), because you’re incorporating the cost of jeans bought plus the markup. 50 * 1.05 is 52.5. The jeans costed $52.50 after the markup.

Length of required side is n = 5 cm

Step-by-step explanation:

We need to find length n of the triangle.

In the given triangle all the three angles are equal and have value =60° So, A triangle that have same angles and angle is equal to 60°, then the triangle is equilateral triangle.

An equilateral triangle has same sides and same angles.

We are given length of one side = 5 cm, the length of required side will also be 5 cm So, n = 5 cm
