Answer:

  \sqrt[n]{x^a}=x^{a/n}

Step-by-step explanation:

While the "law"

  \sqrt[n]{x^n}=x

may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...

  \sqrt{x^2}=|x|\ne x \quad\text{for x $

The graph of a relation is shown.
Rudik [331]

The values which could be the slope of the line are numbers > 0.

<h3>Which values could be the slope of the line?</h3>

According to the task content, it follows that the given line originates from the lower left quadrant and continues through the upper right quadrant.

It therefore follows that the line is ascending from left to right in which case, the slope of the line is positive.

Hence, the possible values of the slope include the set of numbers greater than 0.

gavmur [86]

Answer:

The value of a is 7.4833. The value of A=29.9262^0 and B=60.0735^0.

Step-by-step explanation:

Consider the provided information.

The required figure is shown below:

We need to find the value of a.

Calculate the value of a by using Pythagorean theorem.

a^2+b^2=c^2

a^2+(13)^2=(15)^2

a^2=225-169

a^2=56

a=7.4833

Hence, the value of a is 7.4833.

Now find the value of angle A as shown:

\sin A=\frac{a}{c}

\sin A=\frac{7.4833}{15}

A=sin^{-1}(0.4989)

A=29.9262^0

Find the value of angle B as shown:

\sin B=\frac{b}{c}

\sin B=\frac{13}{15}

B=sin^{-1}(0.8667)

B=60.0735^0

Hence, the value of A=29.9262^0 and B=60.0735^0.
