Answer:
Step-by-step explanation:
Get the perimeter of the each shape and add it all up to get the total fencing material required.
2 square flower beds = 2 x 4a = 8a
1 rectangular play ground = 2l + 2w
total fencing material = 8a + 2l + 2w
0.985 is the median.

Answer:
1944x^2.
Step-by-step explanation:
sqrt 2x^2 * sqrt18^5
= sqrt2x^2 * (sqrt(9^5*2^5))
= sqrt 2 x^2 * (sqrt9^5 * sqrt 2^5)
= sqrt2 x^2 * (243* sqrt2^5)
= 2^0.5 (243 * 2^2.5) x^2
= 2^3 * 243 x^2
= 1944x^2.

Step-by-step explanation:
How to write the rule of a function given the table of values. To write the rule of a function from the table is somehow tricky but can be made easier by having prior knowledge of the type of function. If the function is a linear function, plugging any two sets of values from the table into the equation y = ax + b, where a and b are constants to be found and x, y are values taken from the table. Solving the two equations obtained simultaneously gives the values of a and b and hence the required rule.
Similarly, if the function is a quadratic equation, plugging any three sets of values from the table into the equation y = ax^2 + bx + c, where a, b, c are constants to be found and x, y are values taken from the table. Solving the three equations obtained simultaneously gives the values of a, b and c and hence the required rule. For tables with no prior knowledge of the type of function, a series of trial and error will lead us to the solution of the problem.
