Answer:
This is the graph I inputted into desmos.
Step-by-step explanation:
Next time, using a graphing calculator will work! However, making a table for the x and y outputs will also make it easier to graph points.
For example: see attached image of table.
X/y (3/-1 just look at where the a is if it is o. ln the x axis or y axis then look to see if it's positive or negative
Lets start with finding the volume of the pool
The formula for the volume of a rectangular prism is
V=l*w*h where l=length w=width and h=height
plug in the data we know
V=40*20*4
V=3200ft³
Now for the hot tub.
3200ft³*1/4=800ft³
Add the volumes together
3200+800=4000ft³
Answer=4000ft³
Answer:
<em>V = 65.9 cubic millimeters</em>
Step-by-step explanation:
<u>The Volume of a Right Circular Cone</u>
Given a right circular cone of radius r and height h, its volume is calculated as follows:

The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:

Taking pi as 3.14:

Calculating:
V = 65.9 cubic millimeters
Simplified :(5x+4y)(5x−4y)
=(5x+4y)(5x+−4y)
=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)
=25x2−20xy+20xy−16y2
=25x2−16y2
hope this helps!
