A simple ratio will probably work. 10=3
x=9?
Cross multiply. 3x= 90 This x=30

X will equal 30. If y equals 9, then that means it was multiplied 3 times, so you do the same with x. 10*3=30.

One of the roots of the equation 5x2−36x+t=0 is five times as big as the other root. Find the value of t.
Bas_tet [7]

Answer:

  t = 36

Step-by-step explanation:

If one of the roots is "a", the equation can be factored as ...

  (5x -a)(x -a) = 0

  5x^2 -6ax +a^2 = 0

Comparing terms to the given equation, we see that ...

  -6ax = -36x

  a = 6 . . . . . . . . divide by -6

Then ...

  a^2 = t

  36 = t . . . . . . . substitute 6 for a

_____

The roots are 6 and 6/5.

The following equation f(x) = x³ + 0.5x² + 4.5 has only 1 real root. It lies between the interval [-1,0].
melisa1 [442]
We are asked in this problem to find the real root of the polynomial f(x) = x3 + 0.5x2 + 4.5. in this case, to find the root of the equation, we equate the equation to zero. 
<span>f(x) = x³ + 0.5x² + 4.5 = 0 
        2x3 + x^2 + 9 = 0
</span><span>x1=−1.83557
</span>x2=0.66779+1.41619∗i
x3=0.66779−1.41619∗i

answer is -1.84
