Answer:
20160 pounds
Step-by-step explanation:
20 * 15 * 12 = 3600 feet^3 = Volume
3600 feet^3 * 5.6 pounds = 20160 lbs
Answer:
you can divide the answers by the time duration of the exam and get your answer
Step-by-step explanation:
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
Answer:

Step-by-step explanation:
Hello,
We know that when the parabola equation is

the vertex is (h,k) and the focus is

Here, the equation is

so

So,

Then, the focus is

I attached the graph, included the focus so that you can see it :-)
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Since the altitude started at 240 ft then that will be the constant, and, since it descends 30 ft/min, then 30 will be your slope.
