Answer:

x = 8

Step-by-step explanation:

f(x) = \sqrt{3x}

g(x) = \frac{1}{x+3}

(f o g)(x) = f[g(x)]

             = \sqrt{\frac{3}{x+3} }

This function is defined for (x + 3) > 0

(x + 3) - 3 > 0 - 3

x > -3

From the given options x = 8 is the only solution which is greater than -3.

Therefore, x - 8 is in the domain of the given function.

State if the three numbers can be the measures of the sides of a triangle.
4vir4ik [10]

Answer:

No. They cannot be the measures of the sides of a triangle.

Step-by-step explanation:

<em>Using Pythagorean Theorem (a² + b² = c²) we can find out if these measures match.</em>

<em>The order for </em><em>a</em><em> and </em><em>b</em><em> doesn't matter, but the measure for </em><em>c</em><em> does. </em><em>c</em><em> is the hypotenuse, the longest side of a triangle. With these measures, </em><em>10</em><em> will be the hypotenuse because it is the longest.</em>

6² + 9² = 10²  <em>If this is true, then the measures can be sides of a triangle.</em>

117 = 100   <em>6 squared plus 9 squared equals 117 but 10 squared equals 100. They do not match so the answer is no.</em>
