Answer:
133,787 residents
Step-by-step explanation:
First thing we need to do here is calculate the number of 5 years between 2020 and 1990
That would be 2020-1990 = 30/5 = 6
Now to estimate the present population, we will be needing an exponential equation
P = I(1-r)^n
where P is the present population at 2020
I is the population at 1990 which is 182,000
r is the percentage decrease every 5 years which is 5% or simply 5/100 = 0.05
n is the number of 5 years between 1990 and 2020 which is 6
Plugging all these values we have;
P = 182000(1-0.05)^6
P = 182000(0.95)^6
P = 133,786.724
To the nearest whole number, P = 133,787 residents
Answer:
C; 17.156
Step-by-step explanation:
a rational number is a number you could put in a ratio or fraction
Yes it is when you graph it it makes a linear line
Let's solve for x and z ~
[ they form co - exterior angle pair ]
now, it's time for x :
First angle z is equal to its vertical opposite angle, and then that angle forms co - interior angle pair with (3x - 28)
That's all... let me know if you have questions ~
