A mysterious flying superhero known as Blue Sky protects the good citizens of Allenville. Unknown to these citizens, Blue Sky is
RUDIKE [14]

Here we want to find the proportional relationship between the number of hours that Abdul charges the suit and the number of hours that he can fly.

We will get the proportional relationship:

y = 2*x

where y is the number of hours that Abdul can fly and x is the number of hours that he charges the suit.

<h3>Proportional relationships:</h3>

A proportional relationship is a linear relationship of the form:

y = k*x

Where k is the constant of proportionality.

We can define:

  • x = number of hours that he charges the suit,
  • y = number of hours that he can fly.

Now we know that if Abdul charges the suit for 1 hour, he can fly for 2 hours, then we have the pair:

  • x = 1
  • y = 2

Replacing that in the proportional relationship we get:

2 = k*1

Now we can solve this for k:

2 = k*1

2/1 = k = 2

From this, we can conclude that the proportional relationship is:

y = 2*x

Find the degree of the polynomial<br> 2x^4y^2+9x^2y^5-3x^4y^4
coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term  2\,x^4\,y^2  contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term  9\,x^2\,y^5  contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term  -3\,x^4\,y^4  contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
