Answer:

5∛7 × x^{5/3} × y³ is answer.

Step-by-step explanation:

we have to simplify the given expression 3√875x⁵y⁹

we use exponent rule for radical   \sqrt[n]{xy} = \sqrt[n]{x} \sqrt[n]{y}

we use this rule is this expression

3√875x⁵y⁹ = ∛875 × ∛x⁵ × ∛y⁹

∛875 = ∛125 ×7 = 5 ∛ 7

using exponent rule for radical \sqrt[n]{x^{m}}=x^{m/n} we get

\sqrt[3]{x^{5} } =x^{5/3}

similarly

\sqrt[3]{y^{9} } = y^{9/3}

putting these values in given expression we get

3√875x⁵y⁹ =  5∛7 × x^{5/3} × y³

therefore, our expression simplifies to 5∛7 ×x^{5/3} × y³.

Answer:

5\sqrt[3]{7}*y^3*x^{\frac{5}{3}}

Step-by-step explanation:

We are asked to simplify the radical expression: \sqrt[3]{875x^5y^9}.

Using exponent rule for radical \sqrt[n]{ab} =\sqrt[n]{a}*\sqrt[n]{b} we can rewrite our expression as:

\sqrt[3]{875x^5y^9}=\sqrt[3]{875}*\sqrt[3]{x^5}*\sqrt[3]{y^9}

\sqrt[3]{875}=\sqrt[3]{125*7}=5\sqrt[3]{7}

Using exponent rules for radical \sqrt[n]{a^m}=a^\frac{m}{n} we will get,

\sqrt[3]{x^5}=(x^5)^{\frac{1}{3}}=x^{\frac{5}{3}}

Using exponent rules for radical \sqrt[n]{a^m}=a^\frac{m}{n} we will get,

\sqrt[3]{y^9}=(y^9)^3=y^{\frac{9}{3}}=y^3

Upon substituting these values in our expression we will get,

\sqrt[3]{x^5}*\sqrt[3]{y^9}=5\sqrt[3]{7}*x^{\frac{5}{3}}*y^3

Therefore, our radical expression simplifies to 5\sqrt[3]{7}*y^3*x^{\frac{5}{3}}.

A 95% confidence interval for the proportion of students achieving a reading achievement score that is above the standard set by
gizmo_the_mogwai [7]
Answer:

0.03

Explanation:

First, you subtract the upper bound of the confidence interval by the lower bound of the confidence interval. Then, you divide that number by 2 to get the margin or error.

In this case: (0.49 - 0.43)/2 = 0.03

finding the distance from (–6, 2) to the origin. Use (0, 0) as (x1, y1). d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1)
Naddik [55]

Answer:

2√10

Step-by-step explanation:

Given the coordinates (-6, 2) and (0,0)

We are to find the distance between the coordinates. Using the distance formula;

d = √(x2-x1)²+(y2-y1)²

d = √(0-2)²+(0+6)²

d = √(-2)²+(6)²

d = √4+36

d = √40

d = √4*10

d = 2√10

Hence the required distance is 2√10

Plz plz plz plz plz plz plz help help help me plz help me I’m begging you plz help me plz
RUDIKE [14]

C.

A doesn't work because x + x + x = 3x, not x^3.

B doesn't work because 14x + 10 - 2x has like terms, 14x and -2x can be combined, bit when you do so you get 14x - 2x, or 12x + 10. (So not 16x + 10)

D doesn't work because 12x^2 + 5x + 10 doesn't simplify; it can only be factored, and you cannot combine 12x^2 and 5x because their variables have different powers.

C, however, works fine. All they did is factor out a 3; if you distribute that 3 again, you get 12x + 16x back, so the two are equal.

A local pizza shop has a membership program for frequent buyers. The membership costs $5 per month and members get a discounted
Len [333]

Answer: Nazim have to pay $35 for 20 slices of pizza.

Monthly cost for x slices =  5+1.5x

Step-by-step explanation:

Let x = number of slices

As per given,

Total monthly cost for x slices = (membership cost) +(discounted price) ×(x)

i.e. Total monthly cost for x slices = 5+1.5x

If x=20

Then, Nazim have to pay = 5+1.5(20)

= 5+30= $35

i..e Nazim have to pay $35 for 20 slices of pizza.

Monthly cost for x slices =  5+1.5x
