(x²+9)*(25(x²-4x+4))
x=±√-36/2, so x=±3i
x=4±√(16-16)/2, so x=2 is a double root
depends on how your teacher instructed you to county roots. there are 2 complex solutions and two real solutions because 2 is a double root. that would be D. however there are only 3 DISTINCT roots, , 3i, -3i, and 2 which would be C. The CORRECT answer to a mathematician would be D
Answer:
1. 8.576%
2. Yes
Step-by-step explanation:
1. Use the calculator
Enter: normalcdf(8, E99, 0, 5.9)
This is equal to .08756.
Convert this number into a percent = 8.756%
2.
First, calculate the residual
Residual = Observed - Predicted = 165 - 2.599(20) + 105.08 = 7.94
Use the calculator
Enter: normalcdf(7.94, E99, 0, 5.9)
This is equal to .0892.
Convert this number into a percent = 8.92%
This would be surprising, because the chance of this happening is very low.
Answer:
Area is the total surface covered by the shape and perimeter is the total length of the shape.
Answer: they are neither
Step-by-step explanation: since none of the points remain side by side but don’t cross at a 90° angle they can be neither parallel or perpendicular
