A quadratic equation is an equation whose leading coefficient is of the second degree. The given quadratic equation can be matched with its solution as shown below.

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

The given quadratic equation can be matched with its solution as shown below,

2x² − 32 = 0 → x = √(32/2) → x = {-4, 4}

4x² − 100 = 0 → x = √(100/4) → x = {-5,5}

x² − 55 = 9 → x = √(9+55) → x = {-8,8}

x² − 140 = -19 → x = √(-19+140) → x = {-11,11}

2x² − 18 = 0 → x = √(18/2) → x = {-3, 3}

Type the correct answer in each box. Round your answers to two decimal places. Subtract vector v = &lt;2, -3&gt; from vector u =
expeople1 [14]

u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>

given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is

θ = tan^{-1}(\frac{v}{u})

thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )

Θ = tan^{-1}(\frac{5}{3}) = 59.04° ( to 2 dec. places )

Someone help me please!

Answer:

7/3

1

1/2

undefined

Step-by-step explanation:

1/1 ÷ 3/7 = 7/3 because you multiply the 1st fraction by the reciprocal of the 2nd

1/1 = 1

1/2 = 1/2

1/0 = undefined;  anything divided by zero is considered to be undefined
