A hovercraft takes off from a platform. Its height h (in meters), t seconds after takeoff. is modeled by
h=-(t-18/(t+4)
What is the maximum height that the hovercraft reaches?​

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

529 and 531

step-by-step explanation:

168

step-by-step explanation:

i am pretty sure that the answer is 168
