Step-by-step explanation:

f(x) = x² - 4

y = x²-4

x = y²-4

x + 4 = y²

y =  \sqrt{x + 4}

In a laboratory experiment a student obtained the following values for the mass density of a metal sample: 5.13 g/cc, 4.98 g/cc,
VMariaS [17]

Answer:

5.104%

Step-by-step explanation:

Given:

The accepted value for the mass density = 4.80 g/cc

Observed values:

5.13 g/cc

4.98 g/cc

5.06 g/cc

5.01 g/cc

Total number of observed values = 4

Mean of the observed values = ( 5.13 + 4.98 + 5.06 + 5.01 ) / 4 = 5.045 g/cc

Now,

The percentage error is calculated as:

\textup{Percent Error}=\frac{\left |\textup{Accepted value-Mean value} \right |}{\left |\textup{Accpeted value} \right |}\times100%

on substituting the values, we get

\textup{Percent Error}=\frac{\left |4.80-5.045\right |}{4.80}\times100%

or

Percentage error = 5.104%

Find the inverse of y=100-x^2
AnnyKZ [126]

Answer:

The inverse  is ±sqrt(100-x)

Step-by-step explanation:

To find the inverse, exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x - 100 = -y^2

Divide by -1

-x +100 = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) =y

The inverse  is ±sqrt(100-x)
