Answer:
3 boxes of maracas
Step-by-step explanation:
9 x 2 = 18
18 ÷ 6 = 3 boxes of maracas
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)
If that is a negative three then the slope is .5 But if the three is not a negative then the answer is -0.1
Area 1st rectangle = 10 * 7 = 70 cm^2
length of 2nd rectangle is 2*7 = 14 cm
Area 2nd = 10 * 14 = 140 cm^2
140/70 = 2
The 2nd triangle was twice as big as the 1st. Answer A
