Find the real solution(s) of the equation. Round your answer to two decimal places when appropriate. 5x^6=30
Elina [12.6K]

Answer:

The real solutions are

x=\sqrt[6]{6}\approx 1.35\\\\\:x=-\sqrt[6]{6}\approx -1.35

Step-by-step explanation:

The solution, or root, of an equation is any value or set of values that can be substituted into the equation to make it a true statement.

To find the real solutions of the equation 5x^6=30:

\mathrm{Divide\:both\:sides\:by\:}5\\\\\frac{5x^6}{5}=\frac{30}{5}\\\\\mathrm{Simplify}\\\\x^6=6\\\\\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}\\\\x=\sqrt[6]{6}\approx 1.35\\\\\:x=-\sqrt[6]{6}\approx -1.35

A bag contains 10 tiles with the letters A, B, C, D, E, F, G, H, I, and J. Five tiles are chosen, one at a time, and placed in a
lora16 [44]
I assume in this item, we are to find at which step is the mistake done for the calculation of the unknown probability. 

For the possible number of arrangement of letter, n(S), the basic principles of counting should be used.
                       = 10 x 9 x 8 x 7 x 6 = 30,240

This is similar as to what was done in Meghan's work.

For the five tiles to spell out FACED, there is only one (1) possibility.

Therefore, the probability should be equal to 1/30,240 instead of the 1/252 which was presented in the steps above.

4) 4x + 3y = 56<br> 2x + y = 24<br> Solve using elimination please show work
lesya [120]

Answer:

x = 8     y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now  4x + 3y = 56

         <u>-6x - 3y = -72</u>

         -2x      =  -16

            x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check:  Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56  So we have the correct values for x and y
