Rain : sunny : overcast
7:11:3
7x + 11x + 3x = 366
21x = 366
x = 366/21
x = 17.43
7(17.43) = 122.01 days rain
11(17.43) = 191.73 days sunny
3(17.43) = 52.29 days overcast
The equation based on the information given will be 2x⁴ + 9x³ - x⁴ - 36x - 16 = 0
<h3>How to illustrate the error?</h3>
It should be noted that the information is simply to compute the value properly. This will go thus:
(x + 4)(x + 2)(2x + 1)(x - 2) = 0.
She multiplied (x + 2)(x - 2) correctly and got x² - 4.
She then made a mistake in multiplying (x + 4)(2x ,+ 1).
Therefore, the second step should be (x² - 4)(2x² + 9x + 4).
The next step will be:
2x⁴ + 9x³ + 4x² - 8x⁴ - 36x - 16 = 0
Therefore, the equation based on the information given will be 2x⁴ + 9x³ - x⁴ - 36x - 16 = 0

The distance between the two coordinates is 9.434
Answer:
$221,990.70
Step-by-step explanation:
here we need to apply the formula for future value ,,,,
Future Value = Present value (1+r/m)^mt
we insert the values we have in their respective positions. 4 29% = 0.0429 when we convert it by dividing by 100%
340, 000 = PV (1+0.0429/4)^4×10
340, 000/1.5322 = PV
PV = $221,990.70
