Answer:


Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the domain and the range
From the complete question, we understand that the study was carried out for 6 days. This represents the domain;
So, we have:
i.e. from day 0 to day 6
Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range
So, the range is:
i.e. from 72mL to 0mL
Answer:
135 degrees
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute


step 2
Remember that the circumference of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft
