Answer:
for points sorry nsm km dj
1. 924.849971 rad s
2. 2031.6719 rad s
Answer:
u+v=7-7i
u-v=3+3i
Step-by-step explanation:
u+v
(5-2i)+(2-5i)
Put like terms together:
(5+2)+(-2i-5i)
Simplify:
7+-7i
7-7i
u-v
(5-2i)-(2-5i)
Distribute:
(5-2i)+(-2+5i)
Put like terms together:
(5-2)+(-2i+5i)
3+3i
Hey there!
To start, the domain of a function is the set of x values a function has, in other words, the values the function has on the x-axis.
In this function, the graph appears to have a function going on infinitely in both directions (left and right). Because of this, your domain in interval notation would be (-∞,∞)
**Your interval notation would be in parenthesis because you cannot include negative or positive infinity as one of your values since while your graph is approaching these values, it never really reaches it.
Hope this helps and have a wonderful day! :)
Solution :
Let the distance of the stick from one break be X
And let us assume that 
.
Here, l = length of stick
Therefore, 
We know that, 
, so by definition we get
The cumulative distribution function for R is
When it starts at zero, then r =0. It ends at one when the r has a maximum
value of one.
The probability density function is given by
Now integrating, we find E(R) and 
gives :
Therefore, Var(R)=
