Answer:
The value of Y is 2.09443
Step-by-step explanation:
We have to find the value of Y for the given value of x.
The equation of Y is given by
[tex]Y=\frac{4}{x}+\sqrt x+0.2-5x[/tex]
And the value of x is 4/5. On substituting this value of x in the equation of y, we get
[tex]Y=\frac{4}{\frac{4}{5}}+\sqrt {\frac{4}{5}}+0.2-5\cdot \frac{4}{5}[/tex]
[tex]Y=5+\frac{2}{\sqrt5}+0.2-4[/tex]
Add/subtract the numbers, we get
[tex]Y=2.09443[/tex]
Therefore, the value of Y is 2.09443
By substituting the value of X as X=4/5 and calculating the value of Y in the formula [tex]Y=\frac{4}{x}+\sqrt{x}+0.2-4x[/tex], we get, the value of Y is 2.094.
Given information:
The value [tex]X=4/5[/tex]
The expression [tex]Y=\frac{4}{x}+\sqrt{x}+0.2-4x[/tex]
Now, to get value of y By substituting the value of X as X=4/5 and calculating the value of Y
Put the value of X in the given expression.
[tex]Y=\frac{4}{5}+\sqrt{\frac{4}{5}}+0.2-5(\frac{4}{5)} \\ \\Y=5+\frac{2}{\sqrt{5} }+0.2-4\\\\Y=2.094[/tex]
Hence, the value of Y is 2.094
