Runners in a long distance race start out going 6 kilometers east and then head north for the remainder of the race. the finish line is 10 kilometers from the starting line. how far did the runners travel north?

Step-by-step explanation:

alright lets get started.

Please refer the diagram I have attached.

the runner traveled, six kilometers east.

Next, they turn to north and suppose they run x kilometers.

The starting and the ending points distance is 10 kilometers.

There will be a right triangle formed, we can find the value of x by using Pythagorean theorem.

Subtracting 36 from both sides

So, the runners travel 8 kilometers to the north.     :    answer

Hope it will help.  :)

8 km

Step-by-step explanation:

Data

Then, a rectangular triangle is formed, 10 km is the hypotenuse, 6 km is one side and x km is the other side. From Pythagoras theorem:

10^2 = 6^2 + x^2

100 - 36 = x^2

x = sqrt(64)

x = 8 km

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
