To calculate the time it takes for the penny to hit the ground, we use the formula given relating time and the height of the penny. We calculate as follows:
h = 4.9 (t²) + v0 t + h o
150 = 4.9 (t²) + 0 t + 0
0 = 4.9 (t²) - 150
t = 5.53
t = -5.53
Since in reality there is no time that is negative, the answer would be 5.53 units of time.
The values of the coefficient are ax^2+bx+c=
48x^2-24x+84 and A= 48, B=-24, C=84.
(4x-2)•6(2x+7)=
6•2x+ 6•7
(4x-2)(12x+42)=
4x•12x= 48x^2 4x•42= 168.
-2•12x= -24x -2•42=-84
48x^2-24x+168-84=
48x^2-24x+84=
A= 48, B=-24, C=84
ax^2+bx+c= 48x^2-24x+84.
