Answer:

  y=\dfrac{1}{36}x^2

Step-by-step explanation:

Where p is the distance from focus to vertex, the equation of the parabola with focus at (0, p) is ...

  y=\dfrac{1}{4p}x^2

Your parabola has p=9, so the equation is ...

  y=\dfrac{1}{4\cdot 9}x^2=\bf{\dfrac{1}{36}x^2}

A viewfinder has a triangular lens. Some of the measurement of the length are shown below. Which of the following best represent
S_A_V [24]

Answer:

A

Step-by-step explanation:

First, we need to find the unknown angle of the triangle.

40 + 20 = 60

180 - 60 = 120

So the unknown angle is 120.

Then, we can use the law of sines to create a proportion.

sin(120)/8 = sin(40)/a

Then, we can simplify this.

a is about 5.9, or answer choice A.
