A ray, 𝑅, that emanates from the origin and forms the angle 𝜃 (0 < 𝜃 < 𝜋/2) with the 𝑥-axis intersects the unit circle in point 𝑇. The straight line that touches the unit circle in 𝑇 is a tangent of the unit circle. This line intersects the 𝑥-axis ...Khan Academy. You can learn anything for free. Forever. Try Now.

Both 6 and 9 are divisible by 3. So just like we can reduce fractions, we can also reduce ratios. So if you divide 6 and 9 both by 3. 6 divided by 3 is 2. 6 divided by 3 is 2. And 9 divided by 3 is 3. So we could also say that the ratio of apples to oranges is 2 to 3. Or if we want to use this notation, 2 to 3. 2 to 3. Calculus 1 8 units · 171 skills.

Inductive reasoning starts from the bottom to the top (in this case, 1950 to 2020), and deductive reasoning goes from the top back to the bottom. We can only make a generalization about the future, but to make a prediction about history would use deductive reasoning since we know there was a decrease every year.
