They are same side interior!! Not alternate, they’d be on opposite sides of the line
Answer:
All the three statements presented are indeed valid and satisfy the De Morgan's theorem.
Step-by-step explanation:
The truth tables are presented in the attached images.
a) The statement (X + Y + Z)' = (X'Y'Z') has its proof in the first image attached.
b) The statement (XYZ)' = (X' + Y' + Z') has its proof in the second image attached.
c) The statement (X + YZ) = (X + Y)(X + Z) has its proof in the third image attached.
Answer:
C) 3 cm , 4 cm , 5 cm
Step-by-step explanation:
Using process of elimination and Pythagora's Theorem, find which of the smaller sides, when their squares are found equal to the largest number squared.
A, B, & D are wrong because:
A: 4 + 4 ≠ 16
B: 9 + 25 ≠ 100
D: 16 + 64 ≠ 225
BUT CON THE OTHER HAND 9 + 16 = 25
Answer:
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y
