A can factory requires 2 sheets of metal to make 36 cans and 10 sheets of metal to make 180 cans. The proportionality constant b
Mkey [24]
From the statement above, we can say that there is a direct relationship between the number of sheets used to the number of cans that can be made. That is, # of sheets is directly proportional to # of cans. We make an equation as follows:

let y = # of sheets
     x = # of cans

y = kx      where k is the proportionality constant

Assuming linear relationship of the two, we can use either data point as follows:

y = kx
2 = k(36)
k = 1/18

Therefore, the proportionality constant is 1/18.

A circle has a radius of square root 98 units and is centered at (5.9, 6.7). Write the equation of this circle. Please help!
weqwewe [10]

<u>Given</u>:

Given that the radius of the circle is √98 units.

The circle is centered at the point (5.9, 6.7)

We need to determine the equation of the circle.

<u>Equation of the circle:</u>

The general form of the equation of the circle is given by

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius of the circle.

Substituting the center point (h,k) = (5.9, 6.7) and r = √98, we get;

(x-5.9)^2+(y-6.7)^2=(\sqrt{98})^2

Simplifying, we get;

(x-5.9)^2+(y-6.7)^2=98

Thus, the equation of the circle is (x-5.9)^2+(y-6.7)^2=98
