The area that the plane can fly and be in the zone known as the Bermuda is; 346952 mile²
<h3>How to use the area rule to find the area of a triangle?</h3>
The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.
Now, from the question, we are give;
Side 1 = 900 miles
Side 2 = 930 miles
Angle between two sides = 56°.
Thus, by the area rule we have;
Area = (1/2) * 900 * 930 * sin 56°
Area = 346952 mile²

Y-intercept: -3
Slope: 2
Equation: y = 2x - 3
Step-by-step explanation:
I just answered one since it was only for 5 points. :)
By definition, the span of two vectors is the set of all possible linear combinations of said vectors. So, any element in W is obtaining by choosing two numbers a,b and building
(a)
So, you can show a nonzero polynomial in W by choosing any values of a and b, as long as they're not both zero. To keep it as simple as possible, we can choose for example a=1, b=0 and we obtain one of the base vectors of W:
(b)
Factoring the powers of x, we see that a generic polynomial in W looks like
So, we must build a polynomial
such that it is not possible that
For example, let's try the polynomial 
We should solve the system
And you can check that it has no solutions. So, the polynomial does not belong to W. On the other hand, it surely belongs to V, because it is a polynomial with degree less than 3. So, the polynomial belongs to V/W.
