You can find out BD by using cosine formula which turns out to be 9 cm. Then apply pythagoras theorem on triangle CDA with AD = 5 (14 - 9), to obtain 13 the length of AC. Hence after adding up all the sides perimeter is 42.

An experiment was conducted, and it was determined that plants that received more than two hours of sunlight per day grew larger
8090 [49]

Answer:

C). This is an example of causation

Step-by-step explanation:

Causation : It can be defined as the one event is the result of the other event. It is simply the cause and its effect. There is a causal relation between the two events.

Correlation : It can described the direction of the relation between two or more events or variables.

The conclusion of the experiment is that the plant that received more than two hours of sunlight in each day grew more than the plants that received less than two hours of sunlight in each day.

This is the cause of one event and its effect on the other event.

So option C is correct because sunlight causes plants to grow.

So option C). This is an example of causation.
