What are the real or imaginary solutions of the polynomial x^3=9x​

Mathematics
1 answer:
dem82 [27]3 years ago
8 0

Hello from MrBillDoesMath!

Answer:

 x = 0, +\-3


Discussion:

x^3 = 9x              => subtract 9x from both sides

x^3 - 9x = 0         => factor x from both terms

x(x^2-9) = 0        => x = 0 or x^2 - 9 = 0

x = 0, +\-3

Thank you,

MrB

Someone please help me with #28 and #30 I got myself super confused.
bogdanovich [222]

<u><em>Question 28:</em></u>

S-2\pi r^2=2\pi rh                     Subtract 2\pi r^2 on both sides

\frac{S-2\pi r^2}{2\pi r} =h         Divide 2\pi r on both sides

<u><em>*(Answer)*=</em></u>  \frac{S-2\pi r^2}{2\pi r} =h


<u><em>Question 30:</em></u>

a*t=v_{1}+v_{0}                  Multiply t on both sides

a*t+v_{0} =v_{1}                 Subtract v_{0} on both sides

<u><em>*(Answer)*=</em></u> a*t+v_{0} =v_{1}

Hope This Helps

What is 0.057×10 equal
lbvjy [14]
0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
