Assume the parabola is placed on a graph where the x-axis is the top of the dish.
The vertex is then at (0,-30) The x-intercepts or zeros are at (-30,0) and (30,0)
The equation of such parabola would be:
Plug in vertex to find value of 'a'
Now find the focus given that
Answer: the microphone should be placed 7.5 inches from vertex.

Answer:
Step-by-step explanation:
I would say 8 is the greatest number
the order from least to greatest
-9,-8,-5,-3,-2,0,1,2,4,4,5,6,7,8
Answer:
8,000
Step-by-step explanation:
First there's 2,000 and if they double every 8 years. That means in the first 8 years it will double into 4,000. Lastly, the next 8 years it would double into the population being 8,000.
Answer:
the figure made of two Ray's with a common vertex
Step-by-step explanation:
An angle is formed when two rays share a common endpoint. That common endpoint is called the vertex and the two rays are called the sides of the angle.
the first one the answer is vertex.
the last one is just simply not it.
The domain of h(x) = f(x) /g(x) will be all real numbers without -6 because for -6 will result the denominator equal zero and hence this fraction will be undefined
