Answer:
Step-by-step explanation:
Given
Height H = 4 feet
Velocity = 14ft/s
Required
Time the pumpkin will hit the ground
Using the equation of mottion
H = ut + 1/2gt²
4 = 14t + 1/2(9.8)t²
4 = 14t + 4.9t²
4.9t²+14t-4 = 0
t = -14±√196+16(4.9)/2(4.9)
t = -14±√196+78.4/2(4.9)
t = -14±16.57/9.8
t = -14+16.57/9.8
t = 2.57/9.8
t = 0.2seconds

Answer:
x=2; y=-1
Step-by-step explanation:
Hello,
(1) 6x+7y=5
(2) 2x-3y=7
We multiply equation (2) by 3, it gives
6x-9y=21 and we subtract from (1)
6x-9y-6x-7y=-16y=21-5=16
So y = -1
we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2
thanks
