X^2 - 10x + 36 = 0;
We use the quadratic formula: x = ( - b + or - i\sqrt{ -b^{2}+4ac })/ (2a);
We have a = 1; b = -10; c = 36;
Then, x = ( 10 + or -i\sqrt{44})/2 = 5 + or - \sqrt{11})/2 ;

kirill [66]

Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

v = \frac{d}{t}

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.

This means that d = 200, t = 19.19

So his average speed was of:

v = \frac{d}{t} = \frac{200}{19.19} = 10.42

His average speed was of 10.42 m/s

Arturiano [62]

Answer:

1. <JNL

Step-by-step explanation:

Point N is the vertex of angle 1. Therefore, we can give <1 another name by using 3 letters which includes the letter of vertex point in the middle, and two other letters of the two rays that meets at the vertex point.

Thus, JN and LN meets at point N. Therefore angle 1 can be named as:

<JNL
