![\texttt{Area = Length x Width}\\\\\texttt{Area =}x\times (30-x)=30x-x^2\\\\\texttt{Area =}30x-x^2](/tpl/images/0686/1045/3bde5.png)
Area, A(x) = 30x - x² , as a function of the length (x).Step-by-step explanation:
Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.
If the garden is X yards long, express the Gardens area as a function of length
Let x be the length of garden
So perimeter of rectangle = 60 yard
Perimeter = 2 * ( Length + width)
60 = 2 * ( x + width)
Width = 60/2 - x
Width= 30 - x
![\texttt{Area = Length x Width}\\\\\texttt{Area =}x\times (30-x)=30x-x^2\\\\\texttt{Area =}30x-x^2](/tpl/images/0686/1045/3bde5.png)
Area, A(x) = 30x - x² , as a function of the length (x).Ответ:
the value of the variance is 36
Step-by-step explanation:
The formula for determining variance is
Variance of a set of data = square of the standard deviation. If the standard deviation of a set of data is 6, then the value of the variance would be
Standard deviation^2 = 6^2 = 36
