Answer:

The denominator of the fraction is 2x and the answer is a= - $\frac{b}{2x}$

Step-by-step explanation:

Suppose we have a quadratic equation of the form:

ax²+bx+c

The axis of symmetry of the parabola is given by:

$x= \frac{-b}{2a}$

From here, we must clear the value of a.

For this, we follow the following steps:

1) Pass 2a multiplying to the other side of the equation:

2ax=-b

2) Clear the value of a by passing 2x to divide:

$a= \frac{-b}{2x}$

WARRIOR [948]

The given triangle is a Right angled triangle 

So, by applying Pythagoras theorem :

here's the solution,

=》

$13 {}^{2} = b {}^{2} + 5 {}^{2}$

=》

${b}^{2} = 13 {}^{2} - {5}^{2}$

=》

${b}^{2} = 169 - 25$

=》

${b}^{2} = 144$

=》

$b = \sqrt{144}$

=》

$b = 12$

value of b = 12 yards

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 49.0 and 59.

yKpoI14uk [10]

To find the probability of the statistic class that it could be done at the period at 50.5 and 51.25 minutes and not their usual duration of 49 and 49 minutes so to get the probability you must subtract the time and would come up with 0.75 minutes and then divide it by 10 so the probability is 0.075
