Well when she hits the water h=0 so
2t^2-t-6=0 factor
2t^2-4t+3t-6=0
2t(t-2)+3(t-2)=0
(2t+3)(t-2)=0, since t>0
t=2 seconds...
However it should be noted that h(t)=-2t^2+t+6 implies that
v(t)=dh/dt=-4t+1 and
a(t)=dv/dt=-4
Since this is a free fall equation, this would suggest that the acceleration due to gravity is -4, whether that is supposed to be -4ft/s^2 or -4m/s^2, it certainly is not on this planet! :D If it is -4ft/s^2 it could be on the Moon or if it is -4m/s^2 it could be on Mars.
Answer:
69%
Step-by-step explanation:
Overall grade = 0.35*minor grade + 0.65*major grade
major grade: 0.65*61 = 39.65
minor grade: 0.35*84 = 29.4
total: 39.65+29.4 = 69.05
Rounded = 69%
8.25h= 206.25, this equation would show that however many hours worked times 8.25 needs to equal 206.25 for marvin to be able to buy the game system he wants. Another equation would be 8.25h is greater than or equal to 206.25 or E. Hope i helped.
Answer:
48
Step-by-step explanation:
7-1=6 6 times height which is 8 is 48.
Answer:
the sum deposited was 6000
Step-by-step explanation:
let the sum deposited be p
now we know,
P = (Simple interest × 100 ) / ( rate × time )
- p = 900×100 / ( 5 × 3 )
- p = 90000 / 15
- p = 6000
so the sum deposited was Rs. 6000
