Explain a method of determining the correct degree and classification of a polynomial. Why is this polynomial (4x2y + 5xy) class
Vilka [71]
Well, let's take a peek at each term's degree then \bf 4x^2y+5xy\iff 4x^2y^1+5x^1y^1\qquad 
\begin{cases} & degree\\
4x^2y^1\to 2+1\to &3\\\\
5x^1y^1\to 1+1\to &2
\end{cases}

notice, the degree of a polynomial, is from the exponent value of their variables

The polygons in each pair are similar. Find the missing side length.
worty [1.4K]

Answer:

12

Step-by-step explanation:

We can say that two polygons are similar to each other if both of the polygons have the same shape and their corresponding sides are in the same proportion, hence the ratio of their corresponding sides are equal to each other.

As we can see from the problem since both of the polygons are similar, hence the ratio of their corresponding sides are in the same proportion, therefore let x represent the missing length, hence:

\frac{x}{15} =\frac{32}{40} =\frac{32}{40} \\\\\frac{x}{15} =\frac{32}{40} \\\\x=\frac{32*15}{40} \\\\x=12

Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equ
butalik [34]

Answer: The required point = (1.857,8.643)

Step-by-step explanation:

Equation of circle with center (h,k) and radius r: (x-h)^2+(y-k)^2=r^2

Given: Radius = 5 , center = (0,4)

Eqation of circle: (x-0)^2+(y-4)^2=5^2

x^2+(y-4)^2=25

x^2+(2.5x+4-4)^2=25  [Using equation y = 2.5 x + 4  ]

x^2+(2.5x)^2=25

x^2+6.25x^2=25

7.25x^2=25

x^2=3.44827586207

x=1.857

y= 2.5(1.857)+4

=8.6425

Hence, the required point = (1.857,8.643)

What the median 25,23,17,15,19,21,28,30,26,28
Musya8 [376]

Answer:

D

Step-by-step explanation:

the median is the middle value of a data set in ascending order

If there is not an exact middle then it is the average of the values on either side of the middle

Arrange data in ascending order

15, 17, 19, 21, 23, 25, 26, 28, 28, 30

the middle is between 23 and 25 , hence

median = \frac{23+25}{2} = \frac{48}{2} = 24
