The velocity is 4. You didn’t say what you needed to find but I’m pretty sure it’s that
We are given a coordinate (4,16).
Where first coordinate is the value of x and second coordinate is the value of y for the function y=f(x).
We need to find the value of given point (4,16) for function y= 0.5f(x).
Here function f(x) is being multiplied by 0.5.
On multiplying 0.5 by y, it will effect the value of y only. It does not effect value of x . Because x value is still x. Only function f(x) is being multiplied by 0.5.
Therefore, y= 0.5f(4) = 0.5 * 16 = 8.
So, (4,8) is the point on the graph of y = 0.5f(x) corresponds to (4, 16).
The plane will descend 900 ft every minute
This is the case because we divide 4500 by 5
Hope this helps and have a great day!
Answer:
2
Step-by-step explanation:
The graphs intersect at 2 points.
The 2 solutions are x = -2 and x = 6.
