Answer:
There is just one simple rules for find other side
Step-by-step explanation:
Think about a triangle and this triangle has 3 side it must have 90° on one edge. We assume the longest side is hipotenus x²+y²=hipotenus² . Look at your question hipotenus is 15 lets try to find other side. X²+12²=15² x=9
Answer:
The volume of cylinder is calculated by:
V = base area x height = pi x radius^2 x height
=> 3617.28 = 3.14 x 12^2 x height
=> 3617.28 = 452.16 x height
=> height = 3617.28/452.16 = 8 (cm)
Hope this helps!

First we need to find the value of constant k in equation. To find k we use the formula:
![\int\limits^{100}_0 {ke^{-0.01x}} \, dx =1\\Integrating:\\k\int\limits^{100}_0 {e^{-0.01x}} \, dx =1\\\frac{k}{-0.01}[e^{-0.01x}]_0^{100}=1\\-100k [e^{-0.01x}]_0^{100}=1\\-100k[e^{-0.01*100}-e^{-100*0}]=1\\-100k[e^{-1}-e^0]=1\\-100k(-0.632)=1\\63.2k = 1\\k=0.0158](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B100%7D_0%20%7Bke%5E%7B-0.01x%7D%7D%20%5C%2C%20dx%20%3D1%5C%5CIntegrating%3A%5C%5Ck%5Cint%5Climits%5E%7B100%7D_0%20%7Be%5E%7B-0.01x%7D%7D%20%5C%2C%20dx%20%3D1%5C%5C%5Cfrac%7Bk%7D%7B-0.01%7D%5Be%5E%7B-0.01x%7D%5D_0%5E%7B100%7D%3D1%5C%5C-100k%20%5Be%5E%7B-0.01x%7D%5D_0%5E%7B100%7D%3D1%5C%5C-100k%5Be%5E%7B-0.01%2A100%7D-e%5E%7B-100%2A0%7D%5D%3D1%5C%5C-100k%5Be%5E%7B-1%7D-e%5E0%5D%3D1%5C%5C-100k%28-0.632%29%3D1%5C%5C63.2k%20%3D%201%5C%5Ck%3D0.0158)
the probability that a person age 20 will live for at least 20 more years = P(40 ≤ x <∞).
The person would live for at least 40 years
Therefore:
P(40 ≤ x <∞) =
