Answer:
16x^2 -8x +1
Step-by-step explanation:
The square of a binomial expands as ...
(a +b)^2 = a^2 +2ab +b^2
So, you need to look for a trinomial with first and last terms that are perfect squares and a middle term that is double the product of the roots of those terms.
This pattern matches ...
16x^2 -8x +1 = (4x -1)^2
Answer:
In order to increase humidity by 49.17 grams per kilogram, the increase in temperature will be 18 degree Celsius approx.
Step-by-step explanation:
Initial humidity = 5.75 g/kg
Final humidity= 49.17 g/kg
Percentage increase in humidity= (49.17-5.75)/5.75 *100= 755.13
Increase in temperature= 755.13/43 = 17.56
Increase in temperature = 18 degree Celsius approx.
Use the equation of motion under gravity:-
s = 16t^2 where s is the distance and t = time
2063 = 16t^2
t^2 = 2063 / 16 = 128.94 s
t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second
No decimal can be whole number but the rational number
