<h2>Answer with Explanation </h2>

The pipette is used in chemistry and biological labs. The pipettes are of two types that are volumetric pipette and graduated pipette. The pipette is used to safely handle the chemicals and move liquids from one jar to another. By keeping the finger at the top of pipette the liquid remains inside it as soon as reaching the desired beaker remove the finger the liquids pushed down directly. The pipettes are helpful for measuring the smallest amount of liquid.

The stomata are small openings that can be found on both the upper and the down part of the leaf and they are connected to the plant's vascular system.
These openings enable the plant to get rid of excess water in the form of vapor and to take CO2 from the atmosphere that is essential for the process of photosynthesis. </span>

A model for a company's revenue from selling a software package is R(p)=-2.5p² + 400p, where p is the price in dollars of the software. What price will maximize revenue? Find the maximum revenue.

Answer: p = $80, R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x= $\frac{-b}{2a}$

R(p) = -2.5p² + 400

a= -2.5 b=400

$p=\frac{-(400)}{2(-2.5)}$

= $\frac{-400}{-5}$

=80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

= -16,000 + 32,000

= 16,000
