The given equation is in point-slope form.
The general form of an equation in point slope form is:
Here m is the slope and
and
are the coordinates of the point.
So in given equation the slope is 2/3, and the coordinates of point are (1,3)
Wait what? I don’t understand!! Is that English or..
Answer:
3cube long 2 cube wide and 5 cube prism.
Step-by-step explanation:
-The number that has only 3 absolute divisors
-Since we already know this factors, Sally can create a different prism by altering the dimensional attributes.
-She can create a 3cube long 2 cube wide and 5 cube high prism.
-The new prism still has the same volume of 30 cubic units.
Answer:
s = height above ground
s = 60 + 20 t - 4.9 t^2 (standard physics equation on earth)
at t = 0
s = 60 (clearly :)
now when does it hit the bleak earth?
That is when s = 0
4.9 t^2 - 20 t -60 = 0
solve quadratic and use the positive t (the negative t was back before you threw it if you had thrown it from the ground)
t = 6.09 or - 2.01
use t = 6.09
now to do the last part there are two obvious ways to get t at the peak
1. look for vertex of parabola
2. look for halfway between t = -2.01 and t = 6.09
I will do it the hard (11) waay by completing the square
4.9 t^2 - 20 t = -(s-60)
t^2 - 4.08 t = -.204 s + 12.2
t^2 - 4.08 t +2.04^2 = -.204 s +12.2 + 4.16
(t-2.04)^2 = -.204(s-80.2)
so
top at 80.2 meters at t = 2.04 s
===============
quick check on time
should be average of 6.09 and -2.01
=4.08 /2 = 2.04 check
