Answer:

<h2>1/6</h2>

Step-by-step explanation:

The slope of perpendicular line to the a given line with a known slope is the opposite inverse of that slope. An opposite inverse is the number written as fraction flipped around and its sign changed. (negatives become positives and positives become negatives)

-6 can be written as -6/1

The opposite inverse is 1/6

Answer:

  1/6

Step-by-step explanation:

Perpendicular lines have slopes whose product is -1. That is ...

  -6m = -1

  m = 1/6 . . . . . divide by -6

What is the domain and range of the relation shown?
Helga [31]

Answer:

A.

{-4 ≤ x ≤ 4}

{-4 ≤ y ≤ 4}

Step-by-step explanation:

We’ll domain is the amount of x values,

Range is the amount of y values

_______________________________

Domain:

Starts from -4 to 4

{-4 ≤ x ≤ 4}

I made the sign less than or equal to because the circle lines are solid.

Range:

This starts from -4 to 4 also.

{-4 ≤ y ≤ 4}

<em>Thus,</em>

<em>answer choices A. is correct</em>

Given gif and GHF, write three proportions involving geometric mean.<br>​
almond37 [142]

Answer:

\frac{z}{h}=\frac{h}{y}\\\\\frac{a}{x}=\frac{x}{z}\\\\\frac{a}{w}=\frac{w}{y}

Step-by-step explanation:

For this exercise it is important to remember that a Right triangle is a triangle that has an angle that measures 90 degrees.

According to the Altitude Rule, given a Right triangle, if you draw an altitude from the vertex of the angle that measures 90 degrees (The right angle) to the hypotenuse, the measure of that altitude is the geometric mean between the measures of the two segments of the hypotenuse.

In this case, you can identify that the altitude that goes from the vertex of the right angle (\angle G=90\°) to the hypotenuse of the triangle, is:

GF=h

Then, based on the Altitude Rule, you can set up the following proportion:

\frac{z}{h}=\frac{h}{y}

According to the Leg Rule, each leg is the mean proportional between the hypotenuse and the portion of the hypotenuse that is located directly below that leg of the triangle.

Knowing this, you can set up the following proportions:

\frac{a}{x}=\frac{x}{z}\\\\\frac{a}{w}=\frac{w}{y}

What is the approximate circumference of a semicircle with a radius of 35 inches?
kakasveta [241]

If it were a complete circle, its circumference would be

             (π) x (diameter) = (π) x (2R)  =  70 π inches .

Since it's only half of the circle, the length of the curved part is

                              70 π / 2  = 35 π  =  <em>109.9 inches</em> .

Which equation represents a line that has a slop of 3/4 and passes through the point (2,1)??
Veronika [31]

Answer:

  (B)  4y = 3x-2

Step-by-step explanation:

Divide by the coefficient of y to see the slope. It will be the resulting coefficient of x. Only choices B and D match requirements.

Check to see which equation is satisfied by the given point:

  B: 4(1) = 3(2) -2 . . . . true

  D: 4(1) = 3(2) +5 . . . .false

The appropriate equation is ...

  4y = 3x-2
