A. If you disassemble the shapes and add the numbers, you can get the answer :).
Answer:
Option A.
Step-by-step explanation:
Definition of Boyle's law: a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. There is thus a relationship between volume and pressure of the gas thus option B and C are incorrect.
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
Set up a ratio of height over shadow length:
3.2/1.29 = X/39.25
Cross multiply:
1.29x = 3.2 * 39.25
Simplify:
1.29x = 125.6
Divide both sides by 1.29:
x = 97.364 meters
Round to the nearest meter = 97 meters
