Answer:

PO = 11, LQ = 4, NQ = 12, perimeter of NLP = 24

Step-by-step explanation:

The centroid is the point where the medians intersect each other.

A median divides the side it intersects in 2 equal parts.

So, if NP = 11, then PO = 11

The medians of a triangle intersect each other in the ratio 2:1

So, if NL = 8, then LQ = 4 and NQ = 8+4 = 12

if ML = 10, LP = 5

Finally, the perimeter of the triangle NLP is

NL + NP + LP = 8 + 11 + 5 = 24

Einsteinium-253253253 is an element that loses about \dfrac23

Sedbober [7]

Answer:

$S(t)=450\times(1/3)^t$

Explanation:

The element is <em>einstenium-253</em>. That means that the mass number, i.e. numbrer of protons plus neutrons, of this isotope is 253, but that is not relevant to answer the question.

It is said that the element <em>loses about 2/3 of its mass every month, </em>then to find the remaining amount, every month you have to multiply by 1/3.

With that you can create a decaying function that gives a sample's mass in grams:

$Initial\text{ }mass=M_0\\ \\ Mass\text{ }after\text{ }1\text{ }month=M_0\times1/3\\ \\ Mass\text{ }after\text{ }2\text{ }months=M_0\times(1/3)^2\\ \\ Mass\text{ }after\text{ }3\text{ }months=M_0\times(1/3)^3\\ \\ Mass\text{ }after\text{ }t\text{ }months=M_0\times(1/3)^t$

Now you can replace the initial mass with 450 g and write the specific function for this sample:

$S(t)=450\times(1/3)^t$

"determine the ratio of the volume of a" cone to the volume of a cylinder with the same height and base radius:

hichkok12 [17]

Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence
volume of cone is 10.
