Answer: -245
Step-by-step explanation: The reason is because if you add -245 to -130 you will get her present score which is -375.
-245 + (-130)
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.
The fireworks display occur at 550.331 ft.
