A quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root. Write the equation in general form
andrey2020 [161]
<span>The general form of quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root
=> x = <u>-b  + </u></span><u>√ b^2 – 4 ac</u><span>
                    2a

It is also written as:
=> ax^2 + bx + c = 0

Quadratic equation involves unknown numbers which is x, the numbers which a, b and c are called coeffecients.
There are also quadratic factorization where you factor the polynomial give to be able to get the value of the equation.</span>

Moira said, "If a right triangle has one side with a length of 3 units and one side with a length
Dima020 [189]

If the two sides with length 3 and 4 are the two legs, then the missing side, i.e. the hypotenuse, is indeed 5.

But it could also be the case that 4 is the hypotenuse and 3 is one of the legs. In this case, the missing side is the other leg, so we calculate it using

\sqrt{4^2-3^2}=\sqrt{16-9}=\sqrt{7}

So, a right triangle with legs \sqrt{7} and 3 has an hypotenuse of 4.

Sinxcosxtanx=1-cos^2x
ycow [4]

Step-by-step explanation:

sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ LHS \\= sin  x \: cos  x \: tanx \\  =sin  x \: cos  x \: \times  \frac{sin  x}{cos  x}  \\  = sin  x \: \times  \frac{sin  x}{1} \\  ={sin}^{2}  x \\  = 1 -  {cos}^{2} x \\  = RHS \\  \therefore \: sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ Hence \: Proved.

A wire 48 m long carries a current of 18 A from west to east.
Arisa [49]

Step-by-step explanation:

Given that,

The length of a wire, L = 48 m

Current in the wire, I = 18 A (west to east)

The magnetic field in the wire, B = 8.3\times 10^4\ T (towards south)

The magnetic force acting on the wire is given by :

F=I(L\times B)\\\\F=48\cdot18\cdot8.3\cdot10^{-4}\ N\\\\F=0.71\ N

Using right hand rule, the direction of magnetic force is upwards.
