Answer:

t=64

Step-by-step explanation:

L.C.M. of 2 and 3=6

t^{\frac{1}{6} } =x\\squaring\\ t^{\frac{1}{3} } =x^{2} \\cubing\\t^{\frac{1}{2} } =x^{3} \\x^{2} +x^{3} =12\\when~ x=2\\2^2+2^3=4+8=12\\so~ x=2~ is~ one~ root.\\

By synthetic division.

2| 1   1    0   -12

  |     2    6   12

 -------------------

     1   3    6|0

x²+3x+6=0

disc.=b²-4ac=3²-4×1×6=9-24=-15<0

so roots are imaginary.

x=2

t^{\frac{1}{6} }  =2\\t=2^6=64

if the statement is as given by Sadievigil  then he or she is correct otherwise refer to my solution.

If Courtney walks 3 miles in 80 minutes, then Courtney will walk how far
ozzi
Divide 80/3 which equals 26.6. So it take Courtney 26.6 minutes to walk 1 mile. Then divide 110/26.6 which equals 4.1.

Courtney walls 4.1 miles in 110 minutes.

State the value of the discriminant. Then determine the number of real roots of the equation. n(7n + 8) = –10
Viktor [21]

Answer:

  a.  -216, 0 real roots

Step-by-step explanation:

The discriminant of ...

  ax² + bx + c = 0

is ...

  d = b² -4ac

When we put your equation into the standard form shown above, we get ...

  7n² +8n +10 = 0

Then we can identify a=7, b=8, c=10. The discriminant is then ...

  d = 8² - 4·7·10 = 64 -280 = -216

___

The interpretation of the discriminant is ...

  • < 0; no real roots (2 complex roots)
  • = 0; one real root (multiplicity 2)
  • > 0; 2 real roots

Your discriminant is -216, so there are 0 real roots.
