Which equation justifies why 93-3√9?

Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression $9^{\frac{1}{3}} = \sqrt[3]{9}$ is correct is.

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

In this problem, the expression is:

$9^{\frac{1}{3}} = \sqrt[3]{9}$

And the equation that shows that this is correct is:

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

Write the expanded form of the expression. 6(4x - 8) simplify your answer.

Lynna [10]

Answer:

Step-by-step explanation:

Use distributive property,

a*(b - c) =a*b - a*c

6(4x - 8) = 6*4x - 8*6

= 24x - 48

In triangle ABC, a=7, b=3 and cos C = 1/2. The value of c is

aalyn [17]

Answer:

Correct option: 2 -> sqrt(37)

Step-by-step explanation:

To solve this problem, we just need to use the law of cosines. This law is used to find the third side of a triangle, when we have the two other sides and the angle between them.

The equation of the law of cosines is:

c^2 = a^2 + b^2 - 2 * a * b * cos(C)

So, we have that:

c^2 = 7^2 + 3^2 - 2 * 7 * 3 * (1/2)

c^2 = 49 + 9 - 21

c^2 = 37

c = sqrt(37)

Correct option: 2

Marcus bought he used 50% on tickets on rides and 1/4 of the tickets on video games and the rest of the tickets in the batting c

GalinKa [24]

Answer:

Therefore Marcus is incorrect.

Step-by-step explanation:

Total ticket that Marcus bought= 100%.

Marcus used 50% of ticket on rides.

and he used $\frac{1}{4}$ of the tickets on the video games.

The percentage form of any number x is

$=100\times x \%$

The percentage form of $\frac{1}{4}$ is

$=\frac{1\times 100}{4} \%$

=25%

Therefore rest tickets are

=Total ticket-( ticket used in rides + ticket used in video games)

=100% - (50%+25%)

=100% - 75%

=25%

Therefore he used 25% of tickets in batting cage.

But he said that Marcus said that he used 24% of ticket in batting cage.

Therefore Marcus is incorrect.
