Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.

<h3>What is the percentage increase of a value?</h3>

It is given by the increase divided by the initial value, and subtracted by 100%.

In this problem:

The initial value is of 1.2 mg.

The increase was of 1.8 mg - 1.2 mg = 0.6 mg.

Hence the percent increase is given by:

P = 0.6/1.2 x 100% = 50%.

1. What are the formulas that help determine the equation of a circle? 2. How are the center, radius and a point on the circle e

Answer: see below

<u>Step-by-step explanation:</u>

1) The equation of a circle is: (x - h)² + (y - k)² = r² where

(h, k) represents the center of the circle
r represents the radius of the circle.

2) If you are given a point on the circle and the center (h, k)

you can input those points into the equation of a circle to find r².

Then input (h, k) and r² to identify the equation of that particular circle.

3) If you divide each term in the equation of a circle by r², you will get:

$\dfrac{(x-h)^2}{r^2}+\dfrac{(y-k)^2}{r^2}=1$

(h, k) is the center of the circle
r is the x-radius and y-radius

The difference between a circle and an ellipse is that an ellipse is in the shape of an oval. In other words, the x-radius and y-radius are different.

The equation of an ellipse is:

$\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1$

(h, k) is the center of the ellipse
a is the x-radius
b is the y-radius
