Y-4=4/3 (x-3)
standard form would be where you is singled out giving the y intercept form
solve for y
y-4=4/3 (x)-4/3 (3)
y-4=4/3 (x)-4
y=4/3 (x)-4+4
y=4/3 (x)
The equation is <span>h(t) = -16t2 + 1600</span>.
When the package hits the ground, h(t) = 0: 0 = -16t2 + 1600 To solve by factoring: 0 = -16(t2-100)0 = -16(t+10)(t-10) t = -10 and +10 seconds.
Since we aren't interested in negative time, t = 10 seconds.
.75x + 8 = y (x being the number of lines) (8 being the initial charge) Then substitute x with any of the numbers above (multiply 0.75 with any) then add 8 dollars in the end..
14+30=44 (from his head to his waist)
76-44=32(he is 76 inch tall so substract 44 from 76 to find the length of feet-waist)
answer is 32
