Nonic polynomial
Step-by-step explanation:
Given
Required
Write in standard form
The standard form of a polynomial is:
So, we have:
The standard form is:
And the name is: Nonic polynomial (because it has a degree of 9)
The graph shows the number of each kind of book in Hero's personal library. A book is

Answer:
Step-by-step explanation:
<u>Probability</u>
The simple probability of a random event can be calculated as the ratio between the possible favorable cases and the total possible cases.
The pie chart shows the number of books in Hero's library grouped by category.
The total number of books is 14 + 10 + 4 + 2 = 30
The number of romance books is 2
Thus, the probability of randomly choosing a romance book out of the total books is:
Simplifying:
This corresponds to the first option

Answer:
1/2
Step-by-step explanation:
When you have two points you need to use the slope formula:
x1 and y1 is the first point and x2 and y2 is the second point, remember that the first number is X and the other is Y so...
1/2 is the slope of the points
the complete question is
<span>Point A has an x coordinate of −2 and lies in a circle with a center at (0, 0) and a radius of 5.
To the nearest tenth, what is the y-coordinate for point A?
A: 4.5
B: 4.6
C: 4.7
D: 4.8
see the attached figure
we know that
the equation of the circle is
(x-h)</span>²+(y-k)²=r²
(h,k) is the center---------> (h,k) is the point (0,0)
r=5 units
so
(x-h)²+(y-k)²=r²--------> (x-0)²+(y-0)²=5²------> x²+y²=25
substitute the value of x=-2 in the equation
(-2)²+y²=25------> y²=25-4------> y=(+/-)√21
the y coordinate of point A is positive----> see the picture
therefore
y=√21-----> 4.58-----> y=4.6
the answer is
the y-coordinate for point A is 4.6
