<h3>What is an
equation?</h3>
An equationi is an expression that shows the relationship between two or more variables and number.
Given that the total number of people who ate lunch is 840, hence:

Any set of 3 points is "coplanar".
![y=x^5-3\\ y'=5x^4\\\\ 5x^4=0\\ x=0\\ 0\in [-2,1]\\\\ y''=20x^3\\\\ y''(0)=20\cdot0^3=0](https://tex.z-dn.net/?f=y%3Dx%5E5-3%5C%5C%20y%27%3D5x%5E4%5C%5C%5C%5C%205x%5E4%3D0%5C%5C%20x%3D0%5C%5C%200%5Cin%20%5B-2%2C1%5D%5C%5C%5C%5C%20y%27%27%3D20x%5E3%5C%5C%5C%5C%0Ay%27%27%280%29%3D20%5Ccdot0%5E3%3D0)
The value of the second derivative for

is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of

is always positive for

. That means at

there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval
![[-2,1]](https://tex.z-dn.net/?f=%5B-2%2C1%5D)
.
The function

is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.
Answer:
The square with side 5 centimeters have a greater area.
Corrected question;
Which has the greater area: a 6‐centimeter by 4.12‐centimeter rectangle or a square with a side that measures 5 centimeters?
Step-by-step explanation:
The Area of a rectangle can be written as;
Area A = length × breadth
Given;
Length = 6 cm
Breadth = 4.12 cm
Substituting the values;
Area of rectangle = 6cm × 4.12cm = 24.72 cm^2
For the square;
Area of a square = length × length
Given;
Length = 5 cm
Substituting the values;
Area of the square = 5cm × 5cm = 25 cm^2
Since 25 cm^2 is greater than 24.72 cm^2
The square has a greater area.
