Answer: 25
Explanation:
The 1st factor is 1.
The 2nd factor is the number itself.
The 3rd factor must be a factor that multiplies itself to get to the number.
The number must be 25, factors = 1, 5, 15
Answer: 
Step-by-step explanation:
Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.
Set up a system of equations:

Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":

Answer: 
Step-by-step explanation:
Given
The length of the shadow is 78 ft
the angle of elevation is 
Suppose the height of the building is 
From the figure, we can write

The height of the building is 45.03 ft
The statement "<span>The rate of change of y with respect to x is inversely proportional to y^4" can be written mathematically as dy/dx = k/y^4
To solve the differential equation, we use variable saparable method.
y^4 dy = kdx
Integrating both sides gives,
y^5 / 5 = kx + A
y^5 = 5kx + 5A = Bx + C; where B = 5k and C = 5A
![y= \sqrt[5]{Bx+C}](https://tex.z-dn.net/?f=y%3D%20%5Csqrt%5B5%5D%7BBx%2BC%7D%20)
