Q: Determine whether the relation is reflexive, symmetric and transitive:Relation R is the set N of natural numbers defined as, ㅤㅤㅤ R = {(x, y) : y = x + 5 and x < 4} |
Answer» EXPLANATION.R is set of N NATURAL number defined as, ⇒ R = {(x, y) : y = x + 5 and x < 4}. As we know that, x and y ∈ N. ⇒ x < 4. Values of x = {1, 2, 3}. ⇒ y = x + 5. Put the value of x = 1 in the equation, we get. ⇒ y = 1 + 5. ⇒ y = 6. Put the value of x = 2 in the equation, we get. ⇒ y = 2 + 5. ⇒ y = 7. Put the value of x = 3 in the equation, we get. ⇒ y = 3 + 5. ⇒ y = 8. ⇒ R = {(1,6), (2,7), (3,8)}. For reflexive. ⇒ x ∈ (a, a) for every a ∈ N. ⇒ (1,1), (2,2), (3,3) ∉ R. So, it is not a reflexive. For transitive. If (a, B) ∈ R then (b, C) ∈ R and (a, c) ∈ R. In this equation no one pair is matched. So, it is not a transitive. For symmetric. If (a, b) ∈ R then (b, a) ∈ R. In this equation no one pair is like this. So, it is not a symmetric. |

abcd is a square of side 8 , m is the centre of the circle taking ad as diameter , E is a point on the side ab such that Ce is tangent to the circle . find the area of the triangle cbe it's urgent no spam please give right answer I will mark brianlist |
|
Answer» Step-by-step explanation: (i)AB, BC and AC are tangents to the circle at E, D and F. BD=30cm,DC=7cm,∠BAC=90 From the theorem stated, BE=BD=30cm Also FC=DC=7cm Let AE=AF=x …. (1) Then AB=BE+AE=(30+x) AC=AF+FC=(7+x) BC=BD+DC=30+7=37cm Consider right TRIANLGE ABC, by Pythagoras theorem we have BC 2 =AB 2 +AC 2
(37) 2 =(30+x) 2 +(7+x) 2
1369=900+60x+x 2 +49+14x+x 2
2x 2 +74x+949–1369=0 2x 2 +74x–420=0 x 2 +37x–210=0 x 2 +42x–5x–210=0 x(x+42)–5(x+42)=0 (x–5)(x+42)=0 (x–5)=0or(x+42)=0 x=5orx=–42 x=5[SINCE x cannot be negative] ∴AF=5cm[From (1)] ThereforeAB=30+x=30+5=35cm (II) AC=7+x=7+5=12cm Let ‘O’ be the centre of the circle and ‘r’ the radius of the circle. Join point O, F; points O, D and points O, E. From the figure, 2 1 ×AC×AB= 2 1 ×AB×OE+ 2 1 ×BC×OD+ 2 ×AC×OC AC×AB=AB×OE+BC×OD+AC×OC 12×35=35×r+37×r+12×r 420=84r ∴r=5 Thus the radius of the circle is 5 cm. |

Find the measure of an angle which is 34° less than its supplement. |
|
Answer» Answer: Let the measure of the ANGLE be x o and the measure of its SUPPLEMENT be (x+34) o . Then, ⟹x = 180 o −(x+34) o
⟹x+x = 146 o
⟹2x = 146 o
⟹x = 146 o /2 ⟹x = 73 o
Hence, the supplement of the GIVEN angle measures 73 o . Step-by-step explanation: |
