Calculus

If: x+2y+3z = 4.5
Then: 1(4.5/3 )+2(4.5/6)+3(4.5/9) = 4.5 because 1.5+1.5+1.5 = 4.5
So: 1(4.5/3)*2(4.5/6)*3(4.5/9) = 3.375 because 1.5*1.5*1.5 = 3.375
Therefore as fractions: x = 3/2, y = 3/4 and z = 1/2
Check: 1(3/2)+2(3/4)+3(1/2) = 4.5
Check: 1(3/2)* 2(3/4)*3(1/2) = 3.375

R = 500/9 times r squared

You have missed off one VERY important piece of information... The SOLUTION to the equation. Without that, we cannot give an accurate answer for the value of x.

For example - substitute the number 5 for x...

52+(2x5)+3=38 - BUT substitute 8 for x, and the answer is 85 !

Two straight lines that intersect.

In the absence of any more data, I think we have to assume that the horizontal velocity (340 m/s) doesn't change. That is, nothing (air or window) slows down the bullet until it hits the wall. And we have to assume that gravity is the only force acting on the vertical velocity of the bullet.

Given those assumptions, the vertical drop of the bullet is (g * t^2) / 2 where t is the time in seconds, and g is the acceleration due to gravity, 9.8 m/sec^2.

The bullet hits the window at time t1 and the wall at time t2, and the drop between times t1 and t2 is 0.5m. Since the distance from the window to the wall is 6.9m, t2 = t1 + 6.9m / 340m/s = t1 + 0.0203 seconds.

So now we can solve (g * t1^2) / 2 + 0.5m = (g * t2^2) / 2 = y for t1 and that will give us values for x and y.

The rest is left as an exercise for the reader.

-2X + 2Y = 4

2Y = 2X + 4

Y = X +2

by inspection, 2

but, you could also 0 out X in original equation

-2(0) + 2Y = 4

2Y = 4

Y = 2

first multiply 3 & 7 then add it with 2

Motion is not infinitely continuous for the fact mass itself is balanced by gravity which creates friction in attempt to perfectly bring one another to a perfectly stable level where it reaches 0, but since they are not perfectly balancing one another it will approach 0 a few times going back and forth between negatives and positives as it slows down to reach an equilibrium. So in a sense motion is continuous in the fact that it never truly reaches a point of perfect uniform rest since it will actually have to go back and forth slowing down intensely each time but never coming to a complete stop.

The square root of 220.72 is 14.85665

-14

0 because 0 times 0 = 0 divided by the other 0 = 0

31 + 32 + 33 = 96

I'm guessing you meant consecutive numbers.

One solution is :

[9/3 x 8/2 x 7 x 6 X 4] + 1 - 5 = [3 X 4 X 7 X 6 X 4] - 4 = 2016 - 4 = 2012

It can be simplified to: 3x3+16x2+41x+4 but divided by what is not given

-14+x=23

Transposing -14 to right hand side. It becomes 14

x=23+14

x=37

Hence the required answer to the problem is 37.

Solve for y:

2x+2y=8

2y=-2x+8

y=-x+4

f(x)=-x+4

I think that's what you mean.
