Firs month         A

Second month  3A

Third month      3*3A = A (3^2)

Fourth month    A(3^3)

Fith month        A (3^4)

nth month        A (3 ^ (n-1) )

That is an exponential model, because the variable (time, n) is the exponent of the formula.

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
