Answer:
The correct option is 4.
4) Doing two distance formulas to show that adjacent sides are not the same length.
Step-by-step explanation:
Parallelogram is a quadrilateral which has opposite sides equals and parallel. Example of a parallelogram are rhombus, rectangle, square etc.
We can prove that a quadrilateral MNOP is a parallelogram. If we find the slopes of all four sides and compare those of the opposite ends, same slopes would indicate the opposite sides are parallel, hence the quarilateral is a parallelogram. We can also find the distance of two opposing sides, and slopes of twp opposing sides to determine whether it is a parallelogram or not. The most difficult approach is that diagonals bisect each other at same point.
However, using only two distance formulas will not give us enough information to determine whether a side is parallel or not.
The question is a bit ambiguous: you may mean
or
Anyway, in both cases, the domain of a function involving a square root is found by imposing the content of the root to be greateer than or equal to zero. So, in the first case you have
In the second case, you have
$91 because 10% of 70 is $7 and 20% of 70 is $14 so 7+14+70= $91
Answer:
A=-3/2
B=3
c=3/2
a=-2
Step-by-step explanation:
Knowing that for 
, 
when t<0 and using the definition of charge
The first term corresponds to q(0), the charge accumulated before t=0, in this case it luckily gives zero so we don't have to worry about it.
Let's proceed and integrate 
then when t>0
![i(t)=3\int_0^t \left[ \int_0^tdt'-\inte_0^t e^{-2t'}dt' \right]dt'=3\left[ t+\frac{1}{2}\left( e^{-2t}-1 \right) \right]=3t+\frac{3}{2}e^{-2t}-\frac{3}{2}\,\, C](https://tex.z-dn.net/?f=i%28t%29%3D3%5Cint_0%5Et%20%5Cleft%5B%20%5Cint_0%5Etdt%27-%5Cinte_0%5Et%20e%5E%7B-2t%27%7Ddt%27%20%5Cright%5Ddt%27%3D3%5Cleft%5B%20t%2B%5Cfrac%7B1%7D%7B2%7D%5Cleft%28%20e%5E%7B-2t%7D-1%20%5Cright%29%20%5Cright%5D%3D3t%2B%5Cfrac%7B3%7D%7B2%7De%5E%7B-2t%7D-%5Cfrac%7B3%7D%7B2%7D%5C%2C%5C%2C%20C)
It is clear that:
A=-3/2
B=3
c=3/2
a=-2
Answer:
<h2>1</h2>
Step-by-step explanation:
t < 2 - t is less than 2
1 is the positive integer as the solution of the inequality t < 2.
