Answer 1

Step-by-step explanation:

3)Given Question:-

Find p[V2) for the following polynomial plx) = x + 2x+ 6.

Correction:- P(x)=x^2+2x+6

Solution:-

Given Polynomial P(x)=x^2+2x+6

Now Substituting x = √2 in P(x) then

=> P(√2)=(√2)^2+2(√2)+6

=> P(√2) = 2+2√2+6

P(√2) = 8+2√2

Answer:-

The value of P(√2) for the given problem is 8+2√2

4) Given :-

The angles of quadrilateral are in the ratio 3:5:9:13.

To find:-

Find all the angles of the quadrilateral ?

Solution:-

The ratio of the angles of a quadrilateral = 3:5:9:13.

Let they be 3X° ; 5X° ; 9X° ; 13X°

We know that

The sum of all interior angles of a quadrilateral is 360°

=>3X° + 5X° + 9X° + 13X° = 360°

=>30X° = 360°

=> X° = 360°/30°

=> X°=12°

now,

3X°=3×12°=36°

5X°=5×12°=60°

9X°=9×12°=108°

13X°=13×12°=156°

Answer:-

The four angles of the given quadrilateral are 36°,60° ,108° and 156°

5) Solution:-
