The following diagram shows the path of a planet around the Sun. Kepler discovered that _____.
Phantasy [73]

The right answer is:

<em>area B = area C</em>

We can solve this problem by using Kepler's laws of planetary motion. There are three Kepler's laws. In this exercise, we need to use the second law. According to this law,<em> a line segment joining a planet and the sun sweeps out equals areas during equals intervals of time. </em>So, a certain planet sweeps out an <em>area B </em>from the point <em>P3 </em>to <em>P4</em> in an interval of time <em>t. </em>On the other hand, for the same interval of time <em>t, </em>the planet sweeps out an <em>area C </em>from point <em>P4</em> to <em>P5, </em>that is equal to the previous area according to second kepler's law.

A function is defined by f(x)=6x+1.5. What is f(2.5)
Nataly_w [17]

f(2.5) means x is equal to 2.5.

Replace x in the equation with 2.5 and solve:

6(2.5) + 1.5 = 15 + 1.5 = 16.5

f(2.5) = 16.5
