What is the volume of a sphere with a surface area of ​ 16π ​ft²?
zheka24 [161]
Sphere Surface Area     =    <span> 4 • <span>π <span>• r²
For it to equal 16 PI, then radius must equal 2
4*PI*2*2 = 16 PI

</span></span></span>
Sphere Volume   = <span>  4/3 • <span>π <span>• r³
</span></span></span>
Sphere Volume   = <span>  4/3 • <span>π <span>• 2^3
</span></span></span>
Sphere Volume   = <span> 4/3 *PI * 8
</span>
Sphere Volume   = <span> 32 / 3 PI

</span>
Sphere Volume   = <span> 10.666 PI cubic feet AND I think that is answer B
which SHOULD read 10 (2/3) PI ft^3

I beg for someone. I need a maximum, minimum, domain, and range of polynomial:
elena-s [515]

Answer:

  • domain: all real numbers, (-∞, ∞)
  • range: all real numbers, (-∞, ∞)
  • maximum: +∞
  • minimum: -∞

Step-by-step explanation:

The function is an odd-degree polynomial. The domain and range of any odd-degree polynomial is (-∞, +∞). It has no finite maximum or minimum.

There are 3 local maxima, and 3 local minima. The ones that are non-zero are irrational. Those are about -150.018, -580.455, and 578.545. If you're seriously expected to solve for these values, no doubt you have been given a method for doing so. Use that method.

These local extreme values are reported by the Desmos on-line graphing calculator.

What are the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN¯¯¯¯¯ ?
Brut [27]
<span>(3, 4.5) and (3, 3)

       The midsegment of a triangle is a line connecting the midpoints of two sides of the triangle. So a triangle has 3 midsegments. Since you want the midsegment that's parallel to LN, we need to select the midpoints of LM and MN. The midpoint of a line segment is simply the average of the coordinates of each end point of the line segment. So:

   Midpoint LM:

   ((0+6)/2, (5+4)/2) = (6/2, 9/2) = (3, 4.5)

       Midpoint MN:

   ((6+0)/2, (4+2)/2) = (6/2, 6/2) = (3, 3)

       So the desired end points are (3, 4.5) and (3, 3)</span>
