y is inversely proportional to the squre of X.given that Y=2 when X=6, find the calue of y when x=2
Answers
Answer:
y = 2/9
Step-by-step explanation:
y=x²
y=kx²
2= k(6)²
2= 36k
k= 1/18
The connecting formula is
y= 1/18x²
when y=? , x=2
therefore,
y= 1/18x²
y= 1/18(2)²
y= 1/18(4)
y= 2/9
Answer:
y = 18 when x = 2
Step-by-step explanation:
y ∝ x^2
y = k/x^2
Substituting 'y=2' and 'x=6' to get the value of k:
2 = k/6^2
2 = k/36
k = 36*2
= 72
Hence,
y = 72/x^2
Substituting 'x=2' to get the y-value:
y = 72/2^2
= 72/4
= 18
Hence,
when x =2, y = 18

Step-by-step explanation:
(a + b + c)³ = a³ + b³ + c³ + 3a²b + 3a²c + 3ab² + 3cb² +3 ac² + 3bc² + 6abc
a = 5a ; b =y ; c = z
(5x + y + z)(5z + y + z )(5z + y +z) = (5x + y +z)³
= (5x)³ + y³ +z³ + 3(5x)²y + 3(5x)²z + 3(5x)*y² + 3*z*y² + 3*5x*z² + 3*y*z² + 6*5x*y*z

[tex] \large\underline{\sf{Solution-}}[/tex]
Given Logarithmic expression is

Let first factorize 729
[tex]\begin{gathered}\begin{gathered}\begin{gathered} \:\: \begin{array}{c|c} {\underline{\sf{3}}}&{\underline{\sf{\:\:729 \:\:}}}\\ {\underline{\sf{3}}}& \underline{\sf{\:\:243 \:\:}} \\\underline{\sf{3}}&\underline{\sf{\:\:81\:\:}} \\ {\underline{\sf{3}}}& \underline{\sf{\:\:27 \:\:}} \\ {\underline{\sf{3}}}& \underline{\sf{\:\:9\:\:}}\\\underline{\sf{}}&{\sf{\:\:3 \:\:}} \end{array}\end{gathered}\end{gathered}\end{gathered}[/tex]
So,
[tex] \purple{\rm \longmapsto\:729 = 3 \times 3 \times 3 \times 3 \times 3 \times 3}[/tex]
[tex] \purple{\rm \longmapsto\:729 = {3}^{6} }[/tex]
[tex] \purple{\rm \longmapsto\:729 = {( [{ \sqrt{3} ]}^{2}) }^{6} }[/tex]
[tex] \purple{\rm \longmapsto\:729 = {( \sqrt{3} )}^{12}}[/tex]
So,
[tex]\rm \longmapsto\: log_{ \sqrt{3} }(729) [/tex]
can be rewritten as
[tex]\rm \: = \: log_{ \sqrt{3} }( {( \sqrt{3}) }^{12} ) [/tex]
We know,

So, using this identity, we get
