If a ball is thrown upward at 19.6 meters per second from the top of a building that is 35 meters high, the height of the ball can be modeled by S=35+19.6t−4.9t2, where t is the number of seconds after the ball is thrown. Answer parts a through c.
a. Find the t-coordinate and S-coordinate of the vertex of the graph of this quadratic function.
The t-coordinate of the vertex of the graph of this quadratic function is t=nothing.
(Simplify your answer.)

a: 1/6, j: 1/4

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer: 5100 just subtract

step-by-step explanation:

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
