A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25cm long. What are the l
Bas_tet [7]

Answer:  x =  14.43

Step-by-step explanation:

The Pythagorean Theorem states the following:  

a^2 + b^2 = c^2  

Make one side of the triangle x  

Make the second side of the triangle 2x  

Now, you can plug the values into the equation,  right?  

x^2 + 2x^2 = 25^2 or 625  

3x^2 = 625

Divide each side by 3 and you are left with:  

x^2 =  208.33

Now, take the square root of 208.33

x =  14.43

That is the shorter side. The longer side is twice that value: Therefore, 14.43 x 2 = 28.86 14.43 is one side of the triangle. The other is that same value times two. Therefore, the sides of your triangle are: 14.43 Shorter side 28.86 Longer side

The graph below plots a function f(x):
Karolina [17]
By definition we have that the average rate of change of the function is given by:
 AVR =  \frac{f(x2) - f(x1)}{x2 - x1}

 Substituting values we have:
 AVR = \frac{100 - 50}{2 - 0}
 Rewriting we have:
 AVR = \frac{50}{2}
 AVR = 25
 Answer:
 If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.
