ANSWER
96 yd
EXPLANATION
Let the width of the rectangle be w, then, the length of the rectangle will be:
The area of a rectangle is calculated using the formula:
It was given that, the area of the rectangle is 320yd²
Divide both sides by 5.
Take square root of both sides to get:
This means the length is
The perimeter of a rectangle is given by:
P=2(w+l)
We plug in the values to get:
The perimeter is 96yd
Answer:
Impossible
Step-by-step explanation:
In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:
a = 5; b = -4; c = 3
The quadratic formula is
(ignore the weird capital A)
Substitute a b and c:
Simplify:
Because is the square root of a negative number, the answer would be imaginary.
Therefore, there are not solutions to this equation.
A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.
The graph never meets the x-axis. It looks like this:
Compute the volume of :
Integrate over
:
So the average value of over
is 2/(4/3) = 3/2.
