For first question, you can let t=1.5 and calculate h=140 ft. For second question, we can change the equation to the form of h=-16[(t-2)^2-9]. So you can see from the equation that the maximum height is created when t=2, equals to 144 ft. For question 3, let h=128. From equation, we can get t=3 or t=1. For last question, the rocket hit the lake means h=0, so t=5 or t=-1(not applicable). So the answer is t=5. You can also draw the graphic for the equation to help.
Answer:
HI hydrogen iodide
Step-by-step explanation:
H2(gas)+I2(gas)---------->2HI(gas)
Answer:
None of the options are correct
О E. 289.2 cm
Step-by-step explanation:
Volume of a cylinder = v = л r² h
л = 3.1416 (aprox)
r = radius
h = height
8177 = 3.1416 * 3² * h
8177 = 3.1416 * 9 * h
8177 = 28.2744 * h
8177/282744 = h
h = 289.2 cm
So u Line them up like the photo then you multiply 2 x 4 = 8 and multiply 3 x 1 = 3 so you get 8/3 then simply 8/3 the answer is 2 2/3
He needs 4 eggs, 6 divided by 3 it 2, and 2 times 2 is 4
