Answer:
After 46 years, the population of this country will be doubled.
Step-by-step explanation:
Given that,
The population of a certain country is growing rate 1.5%.
The formula for this is
t= time in years
k=population growth rate.
Here k=1.5% 
= 0.015
≈46 years
After 46 years, the population of this country will be doubled.
Answer:
x = pi n
Step-by-step explanation:
6 sec^2(x) − 6 = 0
Add 6 to each side
6 sec^2(x) − 6+6 = 0+6
6 sec^2(x)=6
Divide by 6
sec^2(x) = 1
Take the square root of each side
sqrt( sec^2(x) ) = ±sqrt(1)
sec(x) =± 1
sec (x) = 1 sec(x) = -1
Take the inverse sec of each side
sec^-1(sec (x)) = sec^-1(1) sec^-1(sec (x)) = sec^-1(-1)
x = 2 pi n x = pi + 2 pi n where n is an integer
Combining
x = pi n
Answer: a screw
Step-by-step explanation:
Answer:
your answer is b 8/10 - 5/10
Step-by-step explanation:
Hey! What you can do is plug them in or solve for x.
This is how you solve for x:
since its x is divided by -4 and you want to get x alone you should multiply -4 to the other side and so it would be x = -4*8.
That is -32.
The answer is A!
Hope this helps!
