Eben, an alien from the planet Tellurango, kicks a football from field level. The equation for the football’s height in meters,

Luden [163]

The maxima of a differential equation can be obtained by getting the 1st derivate dx/dy and equating it to 0.

Given the equation h = - 2 t^2 + 12 t , taking the 1st derivative result in:

dh = - 4 t dt + 12 dt

dh / dt = 0 = - 4 t + 12 calculating for t:

t = -12 / - 4

t = 3 s

Therefore the maximum height obtained is calculated by plugging in the value of t in the given equation.

h = -2 (3)^2 + 12 (3)

h = 18 m

This problem can also be solved graphically by plotting t (x-axis) against h (y-axis). Then assigning values to t and calculate for h and plot it in the graph to see the point in which the peak is obtained. Therefore the answer to this is:

The ball reaches a maximum height of 18 meters. The maximum of h(t) can be found both graphically or algebraically, and lies at (3,18). The x-coordinate, 3, is the time in seconds it takes the ball to reach maximum height, and the y-coordinate, 18, is the max height in meters.

Looking at the repayment time of peer to peer users how would you assume it compares to that every payment via cash or check? wh

Peer-to-peer is good for fast payment but is lacking in the transfer of funds security as there is mostly made b/w people with one unknown history or background, most people meeting for the first time, Compared to cash or check which is handled physically. This is further explained below.

<h3>Looking at the repayment time of peer-to-peer users how would you assume it compares to that every payment via cash or check?</h3>

Generally, P2P, which stands for peer-to-peer, is a method of payment that enables users to make purchases without needing to have access to their financial institution's account information. The transfer is completed quickly and, in most cases, at no cost. There is a generational divide in terms of adoption, but the vast majority of Americans today make use of mobile payment applications.

In conclusion, Peer-to-peer transactions are typically conducted between people who do not know each other's histories or backgrounds, and the majority of transactions involve people who are meeting for the first time. This makes peer-to-peer transactions less secure than cash or checks, which are physically handled. Peer-to-peer transactions are useful for making payments quickly.
