The quadratic function g(x) = ax^2 + bx + c has the complex roots (-5+9i) and (-5-9i). (you may assume that a = -1) what is the

gavmur [86]

Answer:

b = -10, c = -106

Step-by-step explanation:

<h3>Given</h3>

<u>Quadratic function </u>

g(x) = ax^2 + bx + c

with the roots:

(-5+9i) and (-5-9i)

b and c if a = -1

<h3>Solution</h3>

<u>As we know the sum of the roots is -b/a and the product of the roots is c/a. Substituting values and solving for b and c:</u>

(-5 + 9i) + (-5 - 9i) = -b/-1
-10 = b
b = -10

And

(-5 + 9i)(-5 - 9i) = c/-1
(-5)² - (9i)² = -c
25 - 81(-1) = -c
- c = 25 + 81
- c = 106
c = -106

g(x) = -x² -10x - 106

A digital clock displays military time in hh:mm format. Find the probability that the number made up of the first two digits on

egoroff_w [7]

Answer: The probability that the number made up of the first two digits on the clock is less than 25 is 1.

Step-by-step explanation:

The probability of an event is a number which describe the chances of the event will happen.

We know that on digital clock, the first two digits always show as number less that 25.

Therefore, the event that the number made up of the first two digits on the clock is less than 25 is certain. [Since An event that is certain to happen has a probability of 1.]

Hence, the probability that the number made up of the first two digits on the clock is less than 25 is 1.
