The expert phase is different for different tasks. The calculator tries to calculate the sizes of three sides of the triangle from the entered data. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual parameters of the triangle. These are successively applied and combined, and the parameters of the triangle calculate. Calculator iterate until the triangle has calculated all three sides. For example, the appropriate height is calculated from the given area of the triangle and the corresponding side. From the known height and angle, the adjacent side, etc., can be calculated. They use knowledge, e.g., formulas (relations) Pythagorean theorem, Sine theorem, Cosine theorem, Heron's formula, solving equations and systems of equations.The second stage is the calculation of the properties of the triangle from the known lengths of its three sides.

A ball rolls down an inclined plane such that the distance (in centimeters) that it rolls in t seconds is given by s(t) = 2t^3 +
IRISSAK [1]
The ball's velocity will be represented by the derivative of its distance function:

s'(t)=6t^2+6t

Now find the times t for which this is equal to 30, i.e. solve

6t^2+6t=30\implies t^2+t-5=0

This has two solutions, t=-\dfrac{1\pm\sqrt{21}}2, but only one is positive and falls in the interval [0,3]. So the velocity reaches 30 cm/s when t=-\dfrac{1-\sqrt{21}}2\approx1.79.

A carton can hold 1,000 unit cubes that measure 1 inch by inch.describe the dimensions of the carton using unit cubes
Romashka-Z-Leto [24]
You've told us the volume of the carton. 
That doesn't tell us the dimensions.

If the unit cubes have to exactly fit the dimensions,
then all we know is that the dimensions are integers,
and their product is 1,000.

The carton could be

1 by 1 by 1,000
1 by 2 by 500
1 by 4 by 250
1 by 5 by 200
1 by 8 by 125
1 by 10 by 100
1 by 20 by 50
1 by 25 by 40

2 by 2 by 250
2 by 5 by 100
2 by 10 by 50
.
.
and several other possible sets.
