Answer:
Sound requires a material medium to travel , the sound through each medium through its molecules and particles present in it .Sound travels with some speed and it's speed depends upon the nature of the medium through which it travels i.e. upon density and transparently. Speed of increases with the increase in density and decreases with the increases in temperature . Speed if sound us maximum for solid then for liquid and minimum in gases because of it's large intermolecular spaces and low density.
Kenny's score on his 72nd game played is 961
<em><u>Solution:</u></em>
Given that the first 5 score of Kenny are listed below:
38, 51, 64, 77, 90
Kenny's scores follow a pattern
<em><u>To find: Kenny's score on his 72nd game played</u></em>
Let us first find the pattern followed
38, 51, 64, 77, 90
<em><u>Find the difference between terms</u></em>
51 - 38 = 13
64 - 51 = 13
77 - 64 = 13
90 - 77 = 13
So the difference between terms is constant
So the sequence is arithmetic sequence
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant
<em><u>The formula for nth term of arithmetic sequence is given as:</u></em>
= the nᵗʰ term in the sequence
= the first term in the sequence
d = the common difference between terms
Here d = 13 and
So we get,
<em><u>To find the score of 72nd game, substitute n = 72</u></em>
Thus Kenny's score on his 72nd game played is 961
