You can eliminate 81 because we know $\sqrt{81} =9$

The dot is on approximately 9.32 (my estimate) so I would square that number:

(9.32)² = 86.8624 so if you round this you get 87

Imagine that the number line between 9.3 and 9.4 were divided into 5 = parts. Then the red dot would be 1 part to the right of 9.3, which translates into the value

9.32. Find the square of this to determine the value of x: √9.32 = 86.86.

Of the four given possible answers, 87 is the best representation of x.

Use synthetic division to determine whether the number k is an upper or lower bound (as specified for the real zeros of the func

mote1985 [20]

Solution:

The given Polynomial is :

$f(x) = 5x^4 + 4x^3 - 2x^2 + 2x + 4=5( x^4 + \frac{4}{5}x^3 - \frac{2}{5}x^2 + \frac{2}{5}x + \frac{4}{5})$

By Rational Root theorem the of Zeroes of the Polynopmial are:

$\pm\frac{1}{5},\pm\frac{2}{5},\pm\frac{4}{5},\pm1,\pm2,\pm4$

But , $f(\pm\frac{1}{5},\pm\frac{2}{5},\pm\frac{4}{5},\pm1,\pm2,\pm4)\neq 0$

So, no root of this polynomial is real.

Therefore, All the four roots of Polynomial are imaginary.

So, we can't say whether the number k=2, is an upper or lower bound of the polynomial $f(x) = 5x^4 + 4x^3 - 2x^2 + 2x + 4=5( x^4 + \frac{4}{5}x^3 - \frac{2}{5}x^2 + \frac{2}{5}x + \frac{4}{5})$ .

SOVA2 [1]

First you have to make the assumption that these are the only two outcomes. There is also the possibility of hitting the ball and getting out.

However, if we assume that these are the only two cases, we know that the probability is 58.3%. This is because it has been on base 7 times out of 12.
