Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)
Ksivusya [100]
We first rewrite the line y - 3x = – 8 in <span>slope-intercept form as:

                                      y=3x-8.

The form y=mx+n is called the "</span>slope-intercept form" because m tells us the slope and n tells us the y-intercept of the line.

Thus, the slope of the line is 3. We know that if a is the slope of any line perpendicular to our line, then the product of these slopes, 3a, is -1.

This means that the slope a is equal to -1/3. We are also given that the perpendicular line contains (3, 2). Thus, we write the equation:

y-2= -\frac{1}{3}(x-3)\\\\y-2=-\frac{1}{3}x+1\\\\y=-\frac{1}{3}x+3

Answer: y=-\frac{1}{3}x+3

posledela

Answer:

  8, 9, 10, 11, 12

Step-by-step explanation:

Consecutive integer problems are often easier to work if you consider average values. Here, the middle of the 5 consecutive integers is their average, which is 50/5 = 10.

This tells you the integer side lengths are 8, 9, <em>10</em>, 11, 12.

The volume of a cylinder is 628 cm^3. Find the radius of the base if the cylinder has a height of 8 cm. Round your answer to the
dalvyx [7]
I did the problem and checked it on google and did the formula on paper. You would 628= 3.14 * x(squared) * 8, then you would undo everything, leaving you with x= 5

I tried my best, and I don't know if they wanted you to use pi or 3.14 so I hope this is correct :]

A car is on a Ferris wheel with a radius of 20 ft. To the nearest foot, how far does the car travel over an angle of
sertanlavr [38]

The car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet.

In order to determine the distance that the car has travelled, we will use the formula for calculating the circumference of a circle.

<h3>How to calculate Circumference of a circle</h3>

C = 2πr

where

r = radius

Therefore,

r is the radius of the fairy wheel

r = 20 ft

C = 2 × 3.14 × 20

C = 40 × 3.14

C = 125.6 ft

This shows that the car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet
