Rewrite the polynomial in standard form
-x^2/10 +10 -x^3

the figure is a concave pentagon.

step-by-step explanation:

in mathematical context, a pentagon is a flat, two-dimensional closed shape (polygon) with 5 straight sides and 5 angles.

now a pentagon is said to be concave if one or more corners bend inwards and at least one of its angles is 180 degrees or more than 180 degrees.

in the given figure, we can see that we have a corner which is bending inwards and an angle which is clearly greater than 180°. therefore, it is a concave pentagon.

step-by-step explanation:

ok so here is a breif explanation for irrational number,"an irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. instead, the numbers in the decimal would go on forever, without repeating".

first answer,d

2nd=a

3rd=c

example of rational "a rational number is a number that can be written as a ratio. that means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. the number 8 is a rational number because it can be written as the fraction 8/1".

so it would be either c or d.
