Answer:

Therefore

i^{110}=-1

i^{92}=1

i^{245}=i

i^{347}=-i

Step-by-step explanation:

Complex Number :

A complex number is a number that can be expressed in the form

a + bi

where a and b are real numbers, and

' i ' is called an imaginary number.

The value of i is given as

i=\sqrt{-1}

Squaring both the side we get

i^{2}=(\sqrt{-1})^{2}\\\therefore i^{2}=-1

Therefore on substituting we get

For i^110

i^{110}=(i^{2})^{55}=(-1)^{55}=-1

Similarly for i^92

i^{92}=(i^{2})^{46}=(-1)^{46}=1

Similarly for i^245

i^{245}=(i^{2})^{122}\times i=(-1)^{122}\times i=1\times i =i

Similarly for i^347

i^{347}=(i^{2})^{173}\times i=(-1)^{173}\times i=-1\times i =-i

Therefore

i^{110}=-1

i^{92}=1

i^{245}=i

i^{347}=-i

Consider triangle ABC where AB=X+5, BC=X-2, area is 30cm squared. Find X by solving X^2+3X-70=0, and find the perimeter.
klasskru [66]

Answer:

What the hell AC is not given so you can't find the Perimeter

Step-by-step explanation:

  • x^2+3x-70=0
  • (x-7)(x+10)=0
  • x-7=0

       x+10=0

  • x=7

       x=-10

AB=x+5

  • AB=12

        AB=-5

BC=x-2

  • BC=5

        BC=-12

Area of ABC = 30cm2

<u>Perimeter of ABC = AB+BC+</u><u>AC</u>
