Answer:
You divide 5 by 47 and then see if the fourth digit after the decimal is 5 or greater or less than 5. If it's less, the digit before it remains the same and the decimal cuts off at it. If it's 5 or greater, the digit before it goes up one and the. decimal cuts off at it. Using this, you should get 0.106, I think.
There is a typo in the equation:
The equation need to be f(t)= 28t-t2+4
You need to calculate the derivative of f(t): f'(t)= 28-2t
f is increasing if f'(t) is positive ==> 28-2t>0 ==> t<14
f is decreasing if f'(t) is negative ==> 28-2t<0 ==> t>14
f reach its maximum when f'=0 ==> 28-2t=0 ==> t=14
The concentration is increasing between for 0 < t < 14
The concentration is decreasing between for 14 < t < 24
The maximum is achieved when t=14
I hope this will help
The Second Option I know im right
Answer:
Quadrant II
Step-by-step explanation:
Sin is positive in Quad I and II
Cos is negative in Quad II and II
Therefor ∅ is in Quadrant II
The correct answer is D) Miguel: d=23t+10, Gabby d=28t
We multiply the speed of each person by t, the amount of time. This is where the 23t in Miguel's equation and the 28t in Gabby's equation come from. The starting point is added to this, which leads to 23t+10 and 28t+0 or 28t.
