Step-by-step explanation:
Answer:
x=3.2 ft
Step-by-step explanation:
Just subtract them and take the square root.
(50x^2 + 250) -(40x^2 + 350) = x^2=10
x=3.2 ft
Take any 2 points the answer will be the same.
For point 2 and 3 : (-4)-(2)/(0)-(-1) = -6
the answer is -6
Answer:
It simply means getting rid of the square root or radical in the denominator
Step-by-step explanation:
Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.
For example if we want to rationalize the denominator in; 3/√2
We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.
Thus;
(3/√2) × (√2)/(√2)
This gives;
(3√2)2
Answer:
781250 Square Meters
Step-by-step explanation:
Let the dimensions of the rectangular plot be x and y
Farmer Ed wants to enclose three sides of a rectangular plot with a fencing of 2500 meters.
Therefore: Perimeter, P=x+2y=2500
We want to find the largest area that can be enclosed.
Area of the plot, A(x,y)=xy
Substitute x=2500-2y
A(y)=(2500-2y)y
To maximize A, we first find its derivative
The largest area that can be enclosed(at x=1250m,y=625m) is:
1250 X 625
=781250 Square Meters
