<span>The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2  =>

a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0 
576 -  3c^2 = 0 
- 3c^2 = - 576
c^2 = 192
c = 8√3

4505 x 219 standard algorithm
Ymorist [56]

After throughfall calculating the multiplication 4505 x 219 in standard algorithm, we have come to find that product is 986595

<h3>What is standard algorithm?</h3>

In elementary math, a standard algorithm or method is a particular computation technique that is typically taught for resolving particular mathematical issues. In general, these techniques include exchanging, regrouping, long division, long multiplication using a standard notation, and standard formulas for average, area, and volume.

These techniques can vary somewhat by country and time, but they typically include these techniques. Similar techniques are also available for more complex functions like square roots, but they are no longer taught in general mathematics classes because calculators are more convenient.

4505 x 219 in standard algorithm is as follows:

⇒        4 5 0 5

         <u>×    2 1 9  </u>            

        4 0 5 4 5    

    +  4 5 0 5        

  +<u> 9 0 1 0         </u>

     9 8 6 5 9 5

How does the graph of f(x)=x² compare with the graph of f(x)=|x²|
gladu [14]

Answer:

They are the same.

Step-by-step explanation:

The graphs are same because <em>x</em>² is always positive, so the absolute value part is redundant.

The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.Refer to
Dafna11 [192]

Given that

the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.

And we need to find What is the minimum weight of the middle 95% of the players?

Explanation -

Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.

Two standard deviations = 2 x 25 pounds = 50 pounds

So the minimum weight = 200 pounds - 50 pounds = 150 pounds

Hence the final answer is 150 pounds.
