Answer:
x=12
Step-by-step explanation:
you just have to add 2 to both sides to get x by itself and 10+2=12. therefore, x=12
Answer:
d) 0.798
Step-by-step explanation:
Since we know that an exponential function is in form:
, where,
a= Initial value,
b = For growth b is in form (1+r), where r is rate in decimal form.
b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.
Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.
Answer:
x = 6
Step-by-step explanation:

Answer:
given:
principal [P]=8000
rate[r]=15%
population after t years=?
we have
population after t years=P(1+r/100)^t=8000(1+15/100)^t is your answer
