Answer:

yes

Step-by-step explanation:

If you like, you can start with ...

y = x^2

which goes through points (-1, 1) and (1, 1).

You can scale it horizontally by a factor of 10 (so it is 20 units wide) by replacing x by x/10. And you can scale it vertically by a factor of 5 by multiplying the function by 5. Together, these scalings give ...

y = 5(x/10)^2 = (1/20)x^2

The leading coefficient can be written as 1/(4p) with p=5. This (p) is the distance from the vertex to the focus. Since we want the microphone to be located at the focus, it will be 5 inches from the bottom of the dish.

A fish tank has 35 gallons of water in it, but suddenly starts leaking. Water is leaking from the tank at a rate of 1/4 gallon p

Answer:

35 - m

Step-by-step explanation:

A tank containing 35 gallons of water is leaking at a rate of gallon per minute.

"m" represents the number of minutes spent

Number of gallons left in the tank = initial amount of water present – leaked amount of water

Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.

Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute
