If the flare is launched with an initial velocity of 144 feet per second, find the height after 2 seconds. the answer is not 288!

The height = 223.6 ft

Step-by-step explanation:

∵ Initial velocity (u) = 144 ft/sec

∵ t = 2 sec

∵ a = - 32.2 ft/sec²

∵ h = ut + 1/2 at²

∴ h = 144(2) +1/2 (-32.2 × 4) = 288 + 1/2( -128.8) = 223.6 ft

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
