52.8 is the answer.
Hope this helps!
Answer:X=-4
Step-by-step explanation:
We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
Answer: e. An experiment imposes treatments on the subjects, but an observational study does not.
Step-by-step explanation:
Experiment is scientific procedure that is undertaken by an individual or a researcher in order for the person to either make a discovery, or test a hypothesis.
Observational studies are the studies whereby the researchers just observe the impact of a treatment or risk factor e.g. cohort studies. In observational study, the researchers just collect data based on what they've either heard or seen and they've no control over such variables collected whole for an experiment, treatments are applied to a group and the effects are recorded.
Answer:
Therefore my account balance will be in 10 year=$6,750
Step-by-step explanation:
Simple interest: Simple interest is calculated on the same principal each year.

I= simple interest.
r = rate of interest per annum.
t= time
Compound interest: The principal is not same each year. The principal will change from the second year.
The principal of 2nd year = Principal+ interest of 1st year.
The principal of 3rd year = Principal of 2nd year+ interest of 2nd year.
and so on
The Amount 
Here P= $5,000
r=3.5%
and t=10 years

=$1750
Therefore my account balance will be in 10 year=$(5,000+1750)=$6,750.
