That's a progression, for each step you increase the total next number by 8+6.

So
1. 3+8=11
2. 11+8+6=25
3. 25+8+6+6=45
4. 45+8+6+6+6=71
5. 71+8+6+6+6+6=103
6.103+8+6+6+6+6+6=141
7.141+8+6+6+6+6+6+6=185
8.185+8+6+6+6+6+6+6+6=235
9.235+8+6+6+6+6+6+6+6+6=291

a rectangle is inscribed in a circle of radius r. if the rectangle has length 3x, write the area of the rectangle as the product

svetlana [45]

Based on the given condition, since the rectangle is inscribed in a circle given the length to be 3x, the width can be approximated by taking the right triangle formed by the radius and the w/2, sin 45 = w/2/r, which is equal to w = 2r sin45, therefore the Area of the inscribed rectangle = LxW = (3x)(2rsin45)

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

$P(X=x)=\lambda e^{-\lambda x}, x>0$
