Answer: 4 / 5

Explanation:

1) For a right triangle, the ratio sine is defined as:

sin(x) = opposite-leg / hypotenuse

2) x is the angle. In this case: A

3) As per the figure, the opposite leg to tha angle A measures 28

4) As per the figure, the hypotenuse measures 35

5) Calculations:

sin(A) = 28 / 35

Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5

The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 bx c, is shown.step 1: –c = ax2 bxwhich b
Ksju [112]

Answer:

option (b) is correct.

First step to solve for deriving the quadratic formula from the quadratic equation is completing the square.

Step-by-step explanation:

Given : the quadratic equation ax^2+bx+c=0

We have to find the first step for deriving the quadratic formula from the quadratic equation.

Quadratic formula  is given by \frac{-b\pm\sqrt{b^2-4ac}}{2a}

Consider the given quadratic equation ax^2+bx+c=0

Divide the equation by a, we get,

x^2+\frac{b}{a}x+\frac{c}{a}=0

Take \frac{c}{a} to other side, we get,

x^2+\frac{b}{a}x=-\frac{c}{a}

Add (\frac{b}{2a})^2 to both side, we get,

x^2+\frac{b}{a}x+(\frac{b}{2a})^2=(\frac{b}{2a})^2-\frac{c}{a}

Thus, the left side is in the form of (a+b)^2=a^2+b^2+2ab

On solving, we get,

(x+\frac{b}{2a})^2=(\frac{b}{2a})^2-\frac{c}{a}

Then solve for x , we get quadratic formula \frac{-b\pm\sqrt{b^2-4ac}}{2a}

Thus, first step to solve for deriving the quadratic formula from the quadratic equation is completing the square.

Thus, option (b) is correct.
