Answer:
a.
b.
Step-by-step explanation:
a. From the information provided, we can deduce that the population death's follows a Geometric sequence in the form 
where 
and 
#Since the population is reducing, 
can is obtained as 
#The 
term is obtained using the formula 
, given a=1200
The number of ants alive after every month (in first 4 months)
The ant's alive after 4 months is obtained as the value of 
Hence, 936 ants are alive after 4 months.
b. As with the above question, the kitten population follows a geometric sequence: .
#Since it's a growing population , the common ration is the sum of 100% + the growth rate,
and 
and
The population after 4weeks will be:
I’m so confused. Is there any other part to the question?
$4 an hour
5 hours per week times 8 weeks is 40 hours
$160 divided by 40 hours is $4/hr.
It’s addition

Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s
