What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

(3)-2<br> Evaluate exponent

olga nikolaevna [1]

Answer:

$3^{-2} = \dfrac{1}{9}$

Step-by-step explanation:

Definition of negative exponent:

$a^{-n} = \dfrac{1}{a^n}$

In our case, a = 3 and -n = -2.

$3^{-2} = \dfrac{1}{3^2}$

Now we just evaluate the power in the denominator.

$3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{9}$
