step 2 to step 3
Step-by-step explanation:
step 2
2x - 7 = 3 ( add 7 to both sides )
2x = 10 ( error was made here in that they had - 4 )
Answer:
The answer is 4.
Step-by-step explanation:
Using the formula S = ut +1/2at²
S=h= 20ft, u = 2ft/s, and a = 10m/s²
Thus; 20 =2t + 20t²
Therefore; 20t²+2t-20=0
Solving the equation quadratically for the value of t,
we get; t = 1.057 or t=-1.182
But t can not be negative,
Therefore, t= 1.1 seconds (to the nearest tenth)
Bioenergetics it's<span> the term that refers to the study of the biological systems and mechanisms. The study discussed the transformation of energy between living organisms and with their environments. It involves processes and interactions of living organisms, the tracking of the flow of energy from one body into another body.</span>
