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.
1/4 is 0.25 in decimal form and 25/99 is 0.252525 (repeating) in decimal form. they are alike because they are both .25, but different because the decimal form of 25/99 repeats.
Answer:
-3.52
Step-by-step explanation:
-2.2 x (-2) / (- 1/4) x 5 PEMDAS
4.4 / -1.25
-3.52
Answer:
1 I think would be because they have the same tension of 5.0 and that their wavelengths are quite similar
#2 they increase as the tension goes up
#3 The speed would be up because that's what happened in all the other experiment of the waves
