8/24= b/12
The denominator in the first fraction is 2 times greater than the denominator in the second fraction. Thus, this must be the case for the numerators.
b=8/2=4
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.
<h3>Equations of quadratic function</h3>
The standard quadratic function is given as;
ax²+bx + c = 0
From the equation shown above, the leading degree of the equation is 2. The following are condition that must be met before you can use
the quadratic formula to find the solutions of an equation.
- There can be no term whose degree is higher than 2.
- The coefficient of the x²-term can't be zero.
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.

<u>Answer:</u>
The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north.
<u>Step-by-step explanation:</u>
• To find the magnitude of the resultant vector, we have to use Pythagoras's theorem:
where:
a ⇒ hypotenuse (= resultant vector = ? mi)
b, c ⇒ the two other sides of the right-angled triangle (= 452 mil North, 767 mi West).
Using the formula:
resultant² =
⇒ resultant =
⇒ resultant = 890.3 mi
• To find the direction, we can find the angle (labeled <em>x</em> in diagram) that the resultant makes with the north direction:
⇒
⇒
∴ The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north .
