Answer:
Step-by-step explanation:
The relation R is x = y/2 and values of x and y must be in the set A. That is they must be 1 , 2 or 4 and satisfy the relation x = y/2.
So the ordered pairs in this relation are (1, 2) and (2, 4) . Note that 4 cannot be x as that would make y = 8 which is not a member of Set A.
I hope this helps.
Answer:
2 < h <= 3
Step-by-step explanation:
4 + h <= 7
h <= 3 (subtract 4 on both side)
h + 1 > 3
h > 2 (subtract 1 on both side)
So, 2 < h <= 3
Answer:
The rest of question m∠2 = 60°
The prove is as following:
It is given that m∥n , m∠1=65° , m∠2=60° , and BD bisects ∠ABC .
Because of the triangle sum theorem, m∠3= 180° - (65°+60°) = 55° .
∠3 =∠4 By the (Angle Bisector Theorem) ⇒ m∠4=55° .
Using the (Sum of Adjacent Angles), m∠ABC = ∠3 +∠4= 110° .
m∠5 = m∠ABC = 110° because vertical angles are congruent.
m∠5 + m∠6 = 180° ⇒ Co-interior angle property
Substituting gives 110° + m∠6 = 180°
So, m∠6 = 180° - 110° = 70°
Answer:
Step-by-step explanation:
1)
Lines X and W intersect 2 planes, while line Y intersects 3 and linen Z and V intersect one plane,
So, answer is lines X and W (don't know about Y, since it intersects more than two planes)
2) Lines Z and V intersect only one of the planes (the other lines intersect more than one, so don't know about them)
3) Line Y has points in all three planes (the rest have in either 2 or one planes)
Plug i=105, P=700, r=0.05 in the equation i=Prt
105 = 700*0.05*t
105 = 35*t
divide both sides by 35
105/35 = 35*t/35
3 = t
t = 3
