The fireworks display occur at 550.331 ft
The generic equation for a hyperbola provided by: is the best method for solving the problem in this instance.
-
We presume that the y-axis is where the hyperbola's longer axis lies.
In this instance, the sound traveled a total of 1100 meters, and the value of a can be calculated as follows:
2a = 1100
a = 550ft
Given that the two people are 3 miles apart, we can calculate the value of c in feet as follows:
1 mile = 5280 feet
∴ 3 miles = 15840 ft = c
And this is how we may determine what b is worth:



Our equation is thus given by:

And for this case we want to find the value of x when y = 3ft=15840ft and solving for x we get,





x = 550.331 ft.

You have to multiply 2.5 with 3.5 to get the area.
all the other numbers are just nonsense so to find the area you just need to multiply those 2 numbers.
2.5 km×3.5 km=8.75 km²
Answer: A or B
Step-by-step explanation:
First we look for the slope of the line. We know it is parallel to 4x-2y=6. Putting this into slope-intercept form, we get: y=-2x-3. From this we know the slope of the line is -2.
We then find the y-intercept, by plugging in 1 for x and 2 for y in y=-2x+b, and get that 2=-2+b. We now solve for b, which is 4
