The best answer is (x-2)x(x-7) and by solving it you do
x^2-9x+14
x^2-2x-7x+14
xx(x-2)-7x+14
(X-2)x(x-7)

Find the missing factor x^2-11x+18=(x-2)( )
tia_tia [17]
I'd use synthetic div. here, with 2 as my divisor:

      ________________
2   /   1    -11    18
                  2   -18
     ----------------------------
         1     -9      0

Note that the coefficients of the missing factor are given here and are 1 and -9.  Thus, (x-9) is the missing factor.

How far is a chord of length 8 cm from the centre of a circle of radius 5 cm
ivann1987 [24]
  • Answer:

<em>OB = 3 cm</em>

  • Step-by-step explanation:

<em>AO = radius = 5 cm</em>

<em>AB = 8cm/2 = 4 cm</em>

<em>Pythagora</em>

<em>OB² = AO² - AB²</em>

<em>= (5cm)² - (4cm)²</em>

<em>= 25cm² - 16cm²</em>

<em>= 9 cm²</em>

<em>OB = √9cm²</em>

<em>= 3 cm</em>

F(x) = 1 / 2<br> g(x) = x - 4<br> Can you evaluate (g o f) (0)? Explain why or why<br> not.
Vitek1552 [10]

For this case we have the following functions:

f (x) = \frac {1} {2}\\g (x) = x-4

We must find (g_ {o} f) (x). For definition of composition of functions we have to:

(g_ {o} f) (x) = g (f (x))

So:

g (f (x)) = \frac {1} {2} -4 = \frac {1-8} {4} = \frac {-7} {4} = - \frac {7} {4}

Then, for any value of "x", the composite function has a value of- \frac {7} {4}.

Thus,(g_ {o} f) (0)cannot be evaluated, it will always be obtained - \frac {7} {4}.

ANswer:

For any value of "x", the composite function has a value of- \frac {7} {4}.
