4. A rectangular football field measures 56m by 100m. Calculate the distance across the field from one corner to the corner diagonally opposite.

Step-by-step explanation:

The diagonal of the football field is like the hypotenuse of a right-angled triangle.

Therefore we can use the Pythagorean Theorem ( hypotenuse = √(side a² + side b²)

∴ the length from one corner to the next diagonally opposite

                              = √(56² + 100²)

                              = √(13136)

                              = 4 √821

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
