Answer:
≠
Step-by-step explanation:
- 6,2 × 10² = 0 × t + ½ × (-9/8) × t² + 2582,91
- 6,2 × 100 = 0 + ½ × (-9/8) × t × t + 2582,91
- 620 = ½ × (-9/8) × t × t + 2582,91
- 620 = (-9/16) × t × t + 2582,91
- 620 = (-9/16 t²) + 2582,91
- 6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91
Conclusion:
6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91
In order for the polynomial to be a degree of 4, it must have exactly 4 roots. According to the fundamental theorem of algebra: "The number of roots in a function is equivalent to the degree of the function"
These roots do not have to be real numbers, which means they can be imaginary or complex.
In this case, (-11 - √2i), (3 + 4i), and 10. There are three roots, which means that the polynomial can be a third of fourth degree polynomial. It is wrong for Patricia to assume that this is a fourth degree polynomial when only three roots are known.
<h3><u>The degree of the polynomial will at least be three, but could be higher.</u></h3>

Answer:
Correct answer is : $220
Step-by-step explanation:
Here, cost price = $66
Let the selling price be $x.
According to the statement given in problem,
Selling price - cost price = 70% of selling price
i.e. x - 66 = 70% * x
x - 70x/100 = 66
30x / 100 = 66
x = 6600 / 30 = $220
i.e Selling price = $220
