Answer:

Step-by-step explanation:

we have a two right triangle, with one side 115

lets say that the other side of the big right triangle is y

-in the big triangle find the third angle

180 -90 -35 = 55, because the sum of all interior angles in a triangle is 180

tan 55 = opp. /adj= y / 115

y = 115 * tan 55

-in the small right triangle

tan 56 = opp./ adj. = 115 / y-x

y-x = 115/ tan 56 , subtract y from both sides

- x= -y +( 115/tan 56), multiply by -1 both sides

x= y -(115/tan56), substitute y for 115 * tan 55

x= (115*tan 55)- (115/tan56)

x≅86.6685

If, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial

Brut [27]

Answer:

If the electron keeps that speed, then yes.

Step-by-step explanation:

The electron is given an initial position in the space, and is given a positive velocity and a direction towards the origin. Since the distance is finite, eventually, by keeping the same velocity and direction it will reach the origin At some time.

If the speed gradually decreases, it may be the case that the particle will never reach the origin (even though it may never stop), but since the problem doesnt state anything i am assuming that is not the case.

A company reported $50,000 net cash provided by operating activities. It invested $1,000 in equipment and paid $1,000 in dividen

Vinvika [58]

Answer:

The answer is c. $48,000

Step-by-step explanation:

To find the free cash flow, we need to take into account the money that is entering the company and the money that is being used. Money that we are earning is possitive, and money being spend goes with a minus.

The net cash, the $50,000 is our sales column. And is money entering the company.

The Investment would be our CAPEX or directly we can use it as investment. And this money is being spended.

The dividends, are the payments that we are doing to the board of directors or the share holders. Since we are paying others, we know this money is being used.

The equation here is:

Sales - Investment - Dividends = Free Cash Flow

So it $50,000 - $1,000 - $1,000 = $48,000
