A toy rocket shot vertically into the air from launching pad for feet above the ground with initial velocity of 104 ft./s the height H in feet of the rocket above the ground T seconds after launch is given by the function H(t)=-16t^2+140T+4 for how long will it take the rocket to reach his maximum height and what is the maximum height

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

77

step-by-step explanation:

x + 4/7

step-by-step explanation:

use cymath

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
