[input]1- sqrt(10000 / 57000, 5)[/input]

1- sqrt(10000 / 57000, 5) = 1- sqrt(10 / 57, 5) = 1- sqrt(5.7, 5) = 1 - 5.7^(1/5)

Normally * and / are done before + and -. However,1 and 5/16 is taken to be one complete number, as well as 2 and 7/8. Therefore, the terms 21/16 and 23/8 is a division problem.
(21/16)/(23/8)=21/16*8/23=21/2*1/23=21/46.Normally, we are instructed to leave the answer as a fraction unless instructed otherwise.Also, if an answer other than a fraction was asked for there would be a note of how many places to the right of the decimal point were needed. Therefore,my best answer would be 21/46.

A(3x+5x, 3y) and B(x-1, -y)

I hope this answer is correct!!

If there is a typo in the x co-ords of A
such that it should read:

A(3x+5, 3y) and B(x-1, -y).

then

Midpoint x
= (3x+5 + x-1) /2
= (4x+4)/2
= 2x+2

Midpoint y
= (3y + (-y)) /2
= (3y -y) /2
= 2y/2
=y

So, Midpoint AB = (2x+2, y)

However, if it wasn't a typo
then

Midpoint x
= (3x+5x + x-1) /2
= (8x + x-1) /2
= (9x-1)/2
= 4.5x - 0.5

Midpoint y
= (3y + (-y)) /2
= (3y -y) /2
= 2y/2
=y

So, Midpoint AB = (4.5x - 0.5, y)

the answer is simple: run over the function. now, every time you see "x", fill in 2 instead. using the new simple form, calculate the answer. formally, the x is 2, and the y is the answer calculated from the function with the respective "x"es filled in. x=2, y=-11.

Suppose the shadow x feet
Then 16 : 6 = (12 + x) : x
16x = 6 (12 + x)
16x = 72 + 6x
10x = 72
x = 7,2 feet
