In the following figure, m || QR. Then, the measure of ∠QPR is
yulyashka [42]

Given:

m || QR

To find:

The measure of ∠QPR.

Solution:

Since m || QR and a transversal line intersect them, therefore the alternate interior angles are equal.

Let points S and T lie on the line m. S is on the right and T is on the left side of point P.

m\angle RPS=m\angle PRQ

m\angle RPS=45^\circ

Now, angles TPQ, QPR and RPS lie on the one side of a straight line. It means, their sum is 180 degrees.

m\angle TPQ+m\angle QPR+m\angle RPS=180^\circ

50^\circ+m\angle QPR+45^\circ=180^\circ

m\angle QPR+95^\circ=180^\circ

m\angle QPR=180^\circ-95^\circ

m\angle QPR=85^\circ

Therefore, the measure of angle QPR is 85 degrees.

Explain why the expression 9x^3+1/2x^2+3x^-1 is not a polynomial
Nastasia [14]

Answer:

The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.

Step-by-step explanation:

P(x,n) is a polynomial of nth degree if it is of the form,

P(x,n) = a_{0} + a_{1}x + a_{2}x^{2} + a_{3}x^{3} + ......... +a_{n}x^{n}

where n is a finite positive integer and n ∈ N

and 'a_{i}'s are fixed but otherwise arbitrary constants ∀  i = 0(1)n .

Now, the given expression is,

9x^{3} + \frac {1}{2x^{2}} + 3x^{-1}

which  doesn't fit in the above form. Hence, it is not a polynomial.

For men = 5/14*63=5/2*9
=45/2 =22.5
The men would be about 22.5 in the dance recital
