On a rectangular hyperbola, if one point is (2, 3) and y varies inversely to x, find y when x is 6.
pickupchik [31]

Answer:

y = 1

Step-by-step explanation:

y is inversely proportion to x means that ,

y ∝ 1/x or ,

y\  \alpha\  \frac{1}{x}

When we remove the proportionality sign we get,

y=k(\frac{1}{x})\\y=\frac{k}{x} \\

now we know the point is (2 , 3) which means it corresponds to (x , y) which furthermore means y=3 when x=2,

so we insert these values and get the value of k.

y=\frac{k}{x} \\\\3=\frac{k}{2}\\\\6=k\\

now the equation becomes,

y=\frac{6}{x}

now we need to find y when x is 6 so just replace x with 6

y=\frac{6}{x}\\\\y=\frac{6}{6} \\\\y=1

so we get the value of y is 1

James is playing his favorite game at the arcade. After playing the game 33 times, he has 88 tokens remaining. He initially had
zalisa [80]

Answer:

t = 64g

Step-by-step explanation:

This is quite straightforward

Let n be the number of tokens he is charged per game.

88 = 2200 - 33n

33n = 2200 - 88

33n = 2112

n = 2112/33 = 64

Now, we write the relation. The number of tokens t at any point in time is 64 multiplied by the number of games

t = 64g

the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
mestny [16]
<h3>Answer:    18pi</h3>

============================================================

Explanation:

The area 81pi square meters leads to the radius 9 meters

Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.

-----------------

Once you know the radius, you can determine the circumference C

C = 2*pi*r

C = 2*pi*9

C = 2*9*pi

C = 18pi

The circumference is the perimeter, or distance, around the circle.
