<u>Answer:</u>

The correct answer option is \frac{25}{9}.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to evaluate it when a = 5 and k = -2:

[\frac{3^2a^{-2}}{3a^{-1}} ]^k

Substituting the given values of  a and k to get:

[\frac{3^2(5)^{-2}}{3(5)^{-1}} ]^{-2}

\frac{3^{(2\times -2)}.5^{(1\times-2)}}{3^{(-1\times-2)}.5^{(2\times-2)}}

\frac{3^{-4}.5^{-2}}{3^{-2}.5^{-4}}

3^{-2}.5^2

\frac { 1 } { 3 ^ 2 } . 2

\frac { 1 } { 9 } . 2 5

\frac { 2 5 } { 9 }

A rectangular piece of paper has a width that is three inches less than it’s length. It is cut in half along a diagonal to creat
mrs_skeptik [129]

Answer:

(Measure ) L+W :  11 and 8 inches.

These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2

Step-by-step explanation:

Two congruent triangles of 44 sq inch = base 8  height  11  

or base 11 height 8

Finding that both numbers find the same area.

Note for future areas either measure for triangle base + height

8 x 11 or 11 x 8 = 88  when halved its the same answer.  

where 7 x 10 = 35

13 x 10 = 65

and so on;

No other number multiplies its length and height to show 44

What is the slope, m, of the line through (-7, -2) and (-6, 7)?
Nataliya [291]

Answer:

Slope = 9

Step-by-step explanation:

(-7 , -2) ;  x₁ = -7  and  y₁ = -2

(-6 , 7) ;  x₂ = -6  and y₂ = 7

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

          =\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9

sqrt(15+3)

sqrt(18)

sqrt(9*2)

sqrt(9)sqrt(2)

3sqrt(2)

Choice C


2.  6/sqrt(x)

6/sqrt(3)

no radicals in the denominator, multiply by 1 in the form of the radical

6/sqrt(3) * sqrt(3)/sqrt(3)

6sqrt(3)/ (sqrt(3)*sqrt(3))

6sqrt(3)/3
