It will hit the ground when h(t)=0. Since the hammer is simply dropped its initial velocity, v0, is equal to zero and we are told that the initial height, h0, is 25m so our equation is:
h(t)=-4.9t^2+25, we want h(t)=0 so:
4.9t^2-25=0 add 25 to both sides
4.9t^2=25 divide both sides by 4.9
t^2=250/49, since t>0
t=+√(250/49) seconds
t≈2.3 seconds (to the nearest tenth of a second)
x-7> -9
x> -2 (add seven to nine)
Answer:
AB
Step-by-step explanation:
The diameter is the line that goes from one side of the circle to the other passing through the center
The diameter is AB
It could also be named BA
Y-y1=m(x-x1)
y-5=1/6(x-8)
y-5=1/6x-4/3
-1/6x+y=11/3
multiply both sides by -6
x-6y=-22
Answer:
im pretty sure all you have to do is switch the signs (if its negative it will become positive) but only for the points on the x axis so basically (-12,13) would become (12,13)
