What is the degree and classification or the following 8x^2y + 5xy

2 answers:

5 0

I believe the degree of this is 3, assuming that y isn't part of the exponent, and this is a binomial because it has 2 terms.

You need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

8x²y has a degree of 3 (x has an exponent of 2, y has 1, and 2+1=3)
5xy has a degree of 2 (x has an exponent of 1, y has 1, and 1 + 1 = 2)
So, degree = 3

The polynomial has 2 terms, so it's binomial ← classification

The speed of wind and speed of plane in still air are 23 and 135 km/h respectively.

Step-by-step explanation:

Let the speed of wind and speed of plane in still air are w and p km/h respectively.

The effective speed on onward journey was

$p+w=158$ ................(1)

The effective speed on return journey was

$p-w=112$ ..............(2)

Adding equation (1) and equation (2) we get,

⇒ $(p+w)+(p-w) = 158+112$

⇒ $2p = 270$

⇒ $p = 135$

Putting value of $p = 135$ in $p+w=158$ we get:

⇒ $p+w=158$

⇒ $135+w=158$

⇒ $w=23$

Therefore ,The speed of wind and speed of plane in still air are 23 and 135 km/h respectively.

Answer: 3, -3, 3i, -3i

Step-by-step explanation:

$x^4-81=0\\\\Factor:\\(x^2-9)(x^2+9)=0\\(x-3)(x+3)(x^2+9)=0\\\\\text{Apply the Zero Product Property:}\\x-3=0\qquad x+3=0\qquad x^2+9=0\\\boxed{x=3}\qquad \qquad \boxed{x=-3}\qquad \quad x^2=-9\\.\qquad \qquad \qquad \qquad \qquad \qquad x=\sqrt{-9}\\.\qquad \qquad \qquad \qquad \qquad \qquad \boxed{x=\pm 3i}$
