Solve x2 – 8x 41 = 0 for x. x = –4 ± 5i x = 4 ± 5i
Ede4ka [16]
X^2 - 8x + 41 = 0
x = \frac{-(-8)\pm\sqrt{(-8)^2-(4\times41)}}{2}=\frac{8\pm\sqrt{64-164}}{2}\\=\frac{8\pm\sqrt{-100}}{2}=\frac{8\pm10i}{2}=4\pm5i

Please oh please help me I don’t want too fail!
SCORPION-xisa [38]

Answer:

D

Step-by-step explanation:

The best bet would be D because if its going counterclockwise 360 degrees then it would make a full rotation going back to the same position although I would work out the problem to the best of your ability just to make sure because I'm not entirely sure about my answer.

How to solve question 15 and 16
Svet_ta [14]

Answer:

Step-by-step explanation:

16 is especially important, so start with it.

F = 5/9 * C + 32                       Subtract 32 from both sides.

F - 32 = 5/9 C + 32 - 32          Combine

F - 32 = 5/9 C                          Multiply both sides by 9/5

9/5(F - 32) = 9/5 * 5/9 C         Combine

9/5(F - 32) = C

Fifteen

V = pi * r^2 * h / 3                    Multiply both sides by 3

3V = 3*pi * r^2 * h/ 3               Combine

3V = pi * r^2 * h                       Divide by pi

3V/(pi ) = r^2 * h                      Divide by r^2

3V / (pi * r^2) = r^2 * h / r^2   Combine

3V / (pi * r^2) = h
