Answer: yes lol
Step-by-step explanation:
1) 8 turning points means 8 vertices, which implies minimum degree 9 (when the polynomial is x^2 the degree is 2 and it has one turning point).
2) 5 turning points means minimum degree 6, 3 zeros means minimum degree 3, the multiplication implies minimum degree 6+3 = 9
3) 5 times crossing the x - axis is 5 zeros, then the minimum degree is 5.
4) f(x)=x^14 + x^6 + x^9 + x^3,maximum number of turning points 14 -1 = 3 (remember one less than the grade is the maximum posible number of turning points, but it could be less, for example f(x) = x^2 has one turning point).
Answer: 35.88
Step-by-step explanation: So if something is marked up by 8.7% it means, it is 108.7% of the original number.
So we can convert 108.7% to a decimal by dividing 108.7 by 100, which equals 1.087.
So if we want to find the original number, all we have to do is divide 39 by 1.087.
This will give us 35.88 as the original number rounded to the nearest tenth.
