Answer:

Step-by-step explanation:
Given
Shape: Circle
Required
The area and the circumference (relationship)
This implies that, we write an expression that relates the area and the circumference.
Circumference is calculated as:

Area is calculated as:

The area can be rewritten as:

Further rewrite as:

Recall that:
So, the expression becomes


C. (–2, –2), (1, 7), (0, 4) is the correct answer. All three solutions match.
Answer:
Step-by-step explanation:
C=2
Answer:
The answer is D
Step-by-step explanation:
- The resulting number is smaller than the original. This is true because if you take 20 times 0.5 it will equal ten. A decimal is pretty much a fraction in another form.
- The reason why A is false is because if the number isn't being multiplied by 1 then it can't stay the same.
- The reason why B is false is because that is not true as in the example above, 20 times 0.5, it equaled 10 and not less than one.
- The reason why C is false is because the the resulting number simply cannot be higher than the original when being multiplied by a decimal smaller than 1.
