The ratio of male fishes to female fishes is 3 : 2
<u>Solution:</u>
Given, male punky fish = 9 stripes
Female punky fish = 8 stripes.
Total stripes = 86
<em><u>Finding the ratio of male fish to female fish:</u></em>
Let the number of male fishes be "m", and the number of female fishes be "n"
The, given that, total strips = 86
which means, total male strips + total female stripes = 86
The only values that can satisfy above equation are m = 6 and n = 4
Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2
Hence, the ratio of male fishes to female fishes is found out as 3 : 2
The range of this function is y is equal to all real numbers such that y 0.
In order to find the range of y, we must look for the minimum or maximum value. In a quadratic, this number exists at the vertex. To find the vertex, we use the equation -b/2a, where a is equal to the coefficient of x^2 and b is equal to the coefficient of x. Since there is no x, the coefficient is 0.
x value of vertex = -b/2a
x value of vertex = -0/2(1)
x value of vertex = 0
So then we can look for the minimum y value by plugging in the x value into the equation.
y = x^2
y = x^2
y = 0
Therefore the minimum is 0 and there is no maximum.
