Y_Kistochka [10]

Answer: 4.5 metres

Step-by-step explanation:

Using Hooke's Law ()

We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.

Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.

Describe how to sketch the graph of y=2sec(x)-3 using its reciprocal function

blagie [28]

The reciprocal function referred here is the inverse trigonometric function identities. The inverse or reciprocal function of sec x is 1/cos x. Replacing secant with cosine, the equation becomes:

y = (2/cos x) - 3

To graph this, assign random values of x, then you'll get corresponding values of y. Plot the points and connect them together. The graph is shown in the attached picture.
