Answer:

  • f(x) = - (x + 3)² + 12

Step-by-step explanation:

<u>The vertex form:</u>

  • f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola and a-  the leading coefficient

<u>We have on the graph:</u>

  • (h, k) = (-3, 12)

<u>Substitute into equation:</u>

  • f(x) = a(x - (-3))² + 12 = a(x + 3)² + 12

<u>Use the point (0, 3) to find the value of a:</u>

  • 3 = a(0 + 3)² + 12
  • 3 = 9a + 12
  • 9a = 3 - 12
  • 9a = - 9
  • a = -1

<u>So the function is:</u>

  • f(x) = - (x + 3)² + 12

choli [55]

Answer:

The number of boys are 18 and the number of girls are 30.

Step-by-step explanation:

The ratio of number of girls to the boys = 3 : 5

Let the number of girls is g and boys is b initially.

b : g = 3 : 5

5 b = 3 g ..... (1)

Now, girls are 6 + g and boys are b - 9

So, the ratio is

(b - 9) : (6 + g) = 1 : 4

4 b - 36 = 6 + g

4 b - g = 42 .... (2)

From ( 1 ) and ( 2 )

4 b - \frac {5 b}{3}= 42\\\\\frac{7 b }{3} = 42\\\\b = 18

And , g = 5 x 18/3 = 30

So, the number of boys are 18 and the number of girls are 30.
