Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
How you find those is you just divide the rate and what ever answer you get you add a one on the bottom
Example: 1. 4/8
2.4÷8= 2
3. 2/1
Answer: a and b
Step-by-step explanation:
The equation given in the question is
m = <span>0.3048f
when f = 9 feet, then
m = </span><span>0.3048 * 9
= 2.7432 meters
Since the answer has to be shown to the nearest thousandth, so
m = 2.743.meters
The correct option among all the options that are given in the question is the third option or option "C". </span>
So you equal it to 90 and then minus and add the simulators to get x=25
