Answer:

y=\frac{1}{60}x^2

Step-by-step explanation:

The focus of the parabola is (0,15)

and the directrix is y=-15.

The equation of this parabola is given by:

x^2=4py

The vertex of this parabola is at the origin (0,0)

The value of p is the distance from the vertex to the focus.

p=15-0=15

The equation of the parabola is

x^2=4(15)y

x^2=60y

Or

y=\frac{1}{60}x^2

40% of the children in a sports club play badminton. 25% of the children who play badminton also play squash. There are 11 child
Keith_Richards [23]

Answer:

There are 110 children total in the sports club

Step-by-step explanation:

To get this answer, its actually easier than it seems. You might need a calculator however.

First you start with the 11 children who play both badminton and squash, then, you divide that by 0.25 (25%) to get 44.

Next you take 44 and divide it by 0.4 (40%) to get 110.

And there you go! If you want to make sure you got it right simply start with 110 and multiply it by 0.4 then multiply the number/decimal you get by 0.25. You should get 11 to confirm your answer :)

A line is shown in the graph below.
kondaur [170]

Answer:

-2/3

Step-by-step explanation:

This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2. This is why any line that is perpendicular to this line would have slope -2 /1 = -2.
