use algebraic manipulation to find the minimum sum-of-products expression for the function x1x2'x3' + x1x2x4+x1x2'x3x4'

Dennis_Churaev [7]

Answer:

sum of products expression = x₁x₂x₃' + x₁x₂'x₄ + x₁x₂x₄

Step-by-step explanation:

Given function ( f ) = x₁x₂'x₃' + x₁x₂x₄ + x₁x₂'x₃x₄'

using algebraic manipulation

f = x₁ [ x₂'x₃' + x₂x₄ + x₂'x₃x₄' ]

= x₁ [ x₂'( x₃' + x₃x₄') + x₂x₄ ]

next apply Boolean rules

a + bc = ( a + b )(a + c )

a' + a =1

hence

minimum sum-of-products expression = x₁x₂x₃' + x₁x₂'x₄ + x₁x₂x₄

The intercepts of the equation x^2 + 4y^2 = 16 are ___<br> PLEASE HELP

Eva8 [605]

Yintercepts are where x=0
set to zero to solve

0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2

xintercept is where y=0

x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4

yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
