900 / 60 = 15
So, the plane traveled 360,000 meters in 15 minutes.
Generally, we do per hour. So, 15 mins * 4 = 60 mins or 1 hour. Because we multiplied the time by 4, we also need to multiply the distance by 4. 360,000 * 4 = 1440000 meters. The plane was traveling at 1440000 meters per hour.
However, it does not make sense to use meters for this long of a distance. I am going to convert it into miles (let me know if the question asks for a different unit of distance). 1 mile equals 1609.34 meters. Divide 1440000 by 1609.34 to get how many miles. 1440000 / 1609.34 = 894.7767408.
Therefore, the plane is going about 895 miles per hour--pretty fast!

5^0 = 1; 5^1 = 5; 5^2 = 25; 5^(-1) = 1/5; 5^(-2) = 1/25
This is an exponential function since the exponent is a variable.
Function: f(x) = 5^x
Recursive:
f.
Look at f(x) = x^2 for x = -2, -1, 0, 1, 2
f(-2) = 4
f(-1) = 1
f(0) = 0
f(1) = 1
f(2) = 2
Now look at the y-values in the table. They are the same we have here added to 5.
Your function is a quadratic function.
f(x) = x^2 + 5
I think it’s 9.10 but I’m not really sure
Answer:
See explanation
Step-by-step explanation:
The question is incomplete, as the function is not given. So, I will make an assumption.
A quadratic function is represented as:

If
, then the function has a minimum x value
E.g.
------ 
Else, then the function has a maximum x value
E.g.
----
The maximum or minimum x value is calculated using:

For instance, the maximum of
is:


So, the maximum of the function is:
