What is the equation, in standard form, of a parabola that contains the following points?
(-2, -11.5), (0, -2., -20.5)

y = -1.5x2 + 1.5x - 2.5
y = 1.5x2 - 1.5x - 2.5
y = 2.5x2 + 1.5x + 1.5
y = 1.5x2 - 1.5x + 2.5

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

sorry i just need to anwers this to get points
