Notice the picture below
so.. whatever the parabola y= -3x²+k is, will pass over (3,-2) and (-3,-2)
so.. .let us pick say hmmm 3,-2
thus
solve for "k"
The solution would be like this for this specific problem:
<span>Area = L * W = 600
Length = W + 25</span>
<span>Substitute and solve for "W":
(W + 25)W = 600</span>
<span>
w^2 + 25w - 500 = 0
(w - 15) (w + 40) = 0
Positive solution:
Width = 15 meters
Length = 15 + 25 = 40 meters</span>
<span>So, the dimensions of the playground using an
algebraic solution is 15 meters by 40 meters.</span>
To add, the minimum number of coordinates needed to
specify any point<span> within it is the informal definition of the dimension
of a mathematical space.</span>
Step-by-step explanation:
hope, it's right

<span>Well, that depends on how you measure it. If you're simply asking what a drop from 75 to 50 is, that's a drop of 25, which is 33 1/3% of 75. </span>
