We are given with the polynomial function <span>f(x) = 3x3 + 8x2 − 87x + 28 and is asked for the roots of the equation. The function given is a third order polynomial because the highest degree among the polynomials is 3.
In this case, to find the roots of the equation, we equate the function to zero, and then find the values of x.
Thus, the equation becomes </span><span>3x3 + 8x2 − 87x + 28 = 0. We can use an online polynomial finder to determine the roots of the equation. There are three roots of this equation since the order of this polynomial is 3 which are the following:
</span><span><span>Root 1: -7
Root 2: 1/3
Root 3: 4
All factors are real numbers, not imaginary.

To convert a decimal to a percentage, you move the decimal place two spaces to the right.
2.5 would become 250%.
I hope this helps!

1650(1+i)^3 = 2262.7
<span>divide both sides by 1650, take the cube root, then subtract 1 to get i, the annual rate expressed as a decimal. </span>
Sonal went to school for 219 days in a full year. if her attendance is 75 percent find the number of days on which the school was open
700 children, because 1000 times 4 is 4000. 5050-4000=1050. 1050/1.50= 700.
