First of all, thanks for using parentheses. Your doing so made the problem so much clearer than it would have been otherwise.
g(x) = -2 + √(1-x).
What's the domain of this function? Focus on √(1-x). Recall that the domain of the square root function is [0, infinity); in other words, the domain consists of the set of all real numbers equal to or greater than zero (0).
What's the domain of √(1-x)?
Borrowing the comments above, (1-x) must be ≥ 0.
Let's solve this inequality: Add x to both sides. We get 1 - x + x ≥ 0 + x.
Then x ≤ 1 is the domain of the given function.
Answer:
The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the hospital is .
Step-by-step explanation:
We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.
As we know that the Distance-Speed-Time formula is given by;
Here, Distance = 80 miles
Speed = 172 miles per hour
Time = m (the number of minutes)
Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;
Time =
So,
m = 27.91 ≈ 28 minutes.
Hence, it will take 28 minutes for the helicopter to reach the hospital.
The answer is 1,360 square inches :)
