It takes the high-speed train x hours to travel the z miles from Town A to Town B at a constant rate, while it takes the regular

e-lub [12.9K]

Answer:

$\Delta d =\frac{y-x}{y}*d_{Hs}\$

Step-by-step explanation:

Fist the velocity of high-speed train will be given by:

$V_{Hs} =\frac{z}{x}$

And the velocity of the regular will be given by:

$V_{R} =\frac{z}{y}$

The position equations of each movement will be given by:

$d_{Hs} =\frac{z}{x} t$

$d_{R} =z-\frac{z}{y} t$

We can get the encounter point isolating t in the first equation and reepalcing it in the second one:

First isolating:

$d_{Hs}\frac{x}{z} = t$

Second reeplacing t:

$d_{R} =z-\frac{z}{y}*d_{Hs}\frac{x}{z}$

$d_{R}=z-\frac{x}{y}*d_{Hs}\$

In the moment of the encounter the high-speed train have gone round $d_{Hs}\$ and the regular one $\frac{x}{y}*d_{Hs}\$

Then the difference between the distance traveled the high-speed train and the regular one is:

$\Delta d =d_{Hs}-\frac{x}{y}*d_{Hs}\$

$\Delta d =\frac{y-x}{y}*d_{Hs}\$

Answer:

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

1. 0.008

2. Square root of 64 is 8 and cube root of 64 is 4. The difference is 4.

3. Area=100 sq.cm. The side is 10 cm. so the perimeter is 4 x Side= 4x10=40 cm.

4. the two square roots of 25 are 5 and 5. Cuz 5 and 5 gives 25.

Given f (x) = -4x+6, find f (10)

Marina CMI [18]

f ( x ) = - 4x + 6

f ( 10 ) = - 4 ( 10 ) + 6

f ( 10 ) = - 40 + 6

f ( 10 ) = - 34
