Answer:

The acceleration with which particle travel after 1 sec is - 2 mps²  

Step-by-step explanation:

Given as :

The acceleration of particle moving as a(t) = - 3 t + t²

Now, for time period of acceleration = 1  unit

So, At t = 1

A( 1 ) = - 3 ×( 1 ) + ( 1 )²  

Or, A( 1 ) = - 3 + 1

∴   A( 1 ) = - 2  meter per sec²

Hence The acceleration with which particle travel after 1 sec is - 2 mps²  Answer

James believes the honor roll students at his school have an unfair advantage in being assigned to the math class they request.
ivolga24 [154]
If the system is fair, one would expect that the same proportion of students received their requested math class, independent of whether they are on the honor roll or not. We have that from the 356 students on the honor roll, 315 received their requested class. This percentage is around 88.5%, hence 88,5% of honor students get the class they requested. Of the 144 students not on the honor roll, 64 get their requested class. The ratio is 64/144=44.4%. We see that the percentage is a lot smaller, almost half of the percentage for the honor students. Hence, we have that there is actually injustice since if you are an honor student you have almost double the chance to get your preferred class.

The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the following​ equation,
miskamm [114]

Answer: 2008

Step-by-step explanation:

Given : The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the equation y =1.18x +1.58 , where x is the number of years after 2000.

To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get

10.68 =1.18x +1.58\\\\\Rightarrow\ 1.18x=10.68-1.58\\\\\Rightarrow\ 1.18x =9.1\\\\\Rightarrow\ x=\dfrac{9.1}{1.18}=7.7118644067\approx8

The required year will be = 2000+8=2008.

Hence, in 2008  the federal debt will be $10.68 trillion.
