Answer: The length of the second arc is 12 feet.
Step-by-step explanation:
Since we know that
A rope is swinging in such a way that the length of the arc is decreasing geometrically,
Length of first arc = 18 feet
Length of third arc = 8 feet
Let the length of second arc be x
As we know that

Hence, the length of the second arc is 12 feet.

Answer:
The temperature rose by 5 degrees celcius between 11 am and 4 pm
Step-by-step explanation:
Here in this question, we want to find the integer which represents the temperature change from 11 am to 4 pm.
Initially, in the morning, the temperature was -2 . By 11, it had decreased by 3 degrees. What this means is that the temperature went down further by 3 degrees.
Mathematically, the temperature at 11 will be -2-3 = -5 degrees celcius
Now at 4 pm, the temperature went from -5 to 0 degrees.
The temperature change between 11 am and 4 pm will be; 0-(-5) = 0 + 5 = 5 degrees celcius
This means that the temperature rose by 5 degrees celcius between 11 am and 4 pm
