I'm studying Calculus and I think these formulas would be practical for everyday life. Can anyone give me Calculus formula and an example so I can fully understand?

A) Expression
B) Linear equation
C) Equation which is not linear

2)Solve. 11x + 6 = 10x

3)Solve. 4(7x + 10) = 3(9x – 5) + 20

4)Find the mean.
2, 3, 8, 9, 13


5) Solve. 12 – 4x = 20

6) Solve. 6x + 4(3x – 2) = 6x + 2

Suppose M is the center of a circle and A and B two points on the circle circumference. (AB is not a diameter)

The tangent lines on the circle from A and B intersect in C.

CM intersects with the circle in D.

The tangent line of circle from D, intersects with AC and BC in E and F respectively.
***************************
Please show that the area of ADBM is the geometric mean of the areas of ABM and ACBM.

I've always wondered why people bleed so badly when they get cut by broken glass. Does it have to do with the composition of glass (i.e. what substances glass is made of)?

If the present Earth holds a population that is far greater than it ever has been, and also the fact that our technology is getting bigger and bigger; Skyscrapers, oil rigs, piping houses, it all adds up. Would that added weight have any significant affect to the Earth's total weight, and if so would that then cause the Earth's gravitational pull to increase while also lowering the Sun's gravitational pull on the Earth due to it being a bigger mass?
