War your work, please.

Goshia [24]

Answer:

1.) 7. (7 x 7 = 9)

2.) IDK, sorry

3.) 8/27

Apply the product rule to 2/3

2^3/ 3^3

Raise 2 to the power of 3.

8/27

4.) 9

1. Exponentiation: 3 ^ 4 = 81

2. Exponentiation: 3 ^ (-2) = 0.111111111111 = 1/9

3. Multiple: the result of step No. 1 * the result of step No. 3 = 81*1/9 = 81 · 1/1 · 9 = 81/9 = 9 · 9/1 · 9 = 9

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(81, 9) = 9. Cancelling by a common factor of 9 gives 9/1.

In words - eighty-one multiplied by one ninth = nine.

4. Exponentiation: 3 ^ 0 = 1

5.Multiple: the result of step No. 4 * the result of step No. 5 = 9 * 1 = 9

5.) 1/125

5 ^ (-3) = 0.008 = 1/125

6.) IDK, sorry

Evaluate the determinant for the following matrix: 1 4 4 5 2 2 1 5 5

Elina [12.6K]

A Laplace expansion along the first row gives

$\begin{vmatrix}1&4&4\\5&2&1\\1&5&5\end{vmatrix}=1\begin{vmatrix}2&1\\5&5\end{vmatrix}-4\begin{vmatrix}5&1\\1&5\end{vmatrix}+4\begin{vmatrix}5&2\\1&5\end{vmatrix}$
$=1(10-5)-4(25-1)+4(25-2)$
$=1$

The measure of an exterior angle of a regular polygon is 2x and the measure of an interior angle is 4x Find the measure of one i

kolbaska11 [484]

Answer:

Part a) The measure of an exterior angle is 60°

Part b) The measure of an interior angle is 120°

Step-by-step explanation:

step 1

Find the value of x

we know that

A regular polygon has equal sides and equal interior angles

The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)

so

$2x+4x=180$

solve for x

$6x=180$

$x=30$

step 2

Find the measure of an exterior angle

2x

substitute the value of x

$2x=2(30)=60\°$

step 3

Find the measure of an interior angle

4x

substitute the value of x

$4x=4(30)=120\°$

In this problem the regular polygon is a hexagon
