Your nephew is standing on his deck, which is 4 feet off the ground. He tosses his toy up into the air at an initial velocity of 7 feet per second. The equation h = -2t^(2) + 7t + 4 models the toy's height h in feet from the ground at t seconds after he threw it. a) How high is the toy after 0-4 seconds?

Step-by-step explanation:

The height attained by the toy as a function of time t is given by :

h is in feet and t is in seconds

Height of the toy at t = 0

Height of the toy at t = 4 seconds is :

So, between 0 to 4 seconds, height of the toy is 4 feets.

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
