Answer: the eastbound train had travelled 12 miles
Explanation: using Pythagoras theorem, we know that
X^2 = a^2 + b^2
Where ^ stands for raised to power.
Let
a stand for the train going towards North and
b stands for the train going towards east.
X stands for the total distance between train a and b = 20 miles.
By Pythagoras rule
X^2 = a^2 + b^2
20^2 = 16^2 + b^2
400 = 256 + b^2 so that
b^2 = 400 - 256 = 144
b = √144
b = 12 miles.

Identify the function as either a constant, direct variation, absolute value or greatest integer function f (x)=-4
boyakko [2]
Answer: Constant

No matter what the input x is, the output f(x) is going to be -4. Therefore, the output is constant. 

Note: f(x) can be interchanged with y. So we can say y = -4.

Evaluate5− t/3 when t=12 ​
Novosadov [1.4K]

Answer:

1

Step-by-step explanation:

5 -  \frac{t}{3} =  \frac{5}{1} - \frac{12}{3} = 5 - 4 = 1

or

5 -  \frac{t}{3} =  \frac{5}{1} -  \frac{12}{3} =  \frac{15 - 12}{3} =  \frac{3}{3} = 1

Hope this helps ;) ❤❤❤

Find from u.<br><br> -12u = -24
Bingel [31]
Well, to find u, we have to remove all that is attached to it so the equation can just be u=...
   To find u, you have to remove what is attached to it, and that is -12. Then you have to look at the relationship between the -12 and u. The relationship is multiplication, and the opposite of multiplication is division, so all you have to do is divide both sides by -12. So;
-12u/-12=-24/-12
   The -12 cancels the -12, leaving u and the - in 12 cancels the - in 24. Leaving 24/12. And that is 2. Written as;
u=2
   Hope i helped. If you have any more problems, let me know.
