a)
so, if the population doubled in 5 years, that means t = 5. So say, if we use an amount for "i" or P in your case, to be 1, then after 5 years it'd be 2, and thus i = 1 and A = 2, let's find "r" or "k" in your equation.
b)
A = 10,000, t = 3
Formula :
Base²= Hypotenuse² - Perpendicular ²
Remember the a² in formula has nothing to do with the a we have to find. :)
Y intercept is -6
Y= 5x^2-X-6
Y= 5(0)^2-0-6
Y= 0-0-6
28% decrease
Solution:
Calculate percentage change
from V1 = 25 to V2 = 18
(V2−V1)|V1|×100
=(18−25)|25|×100
=−725×100
=−0.28×100
=−28%change
=28%decrease
Hi there!
Use the kinematic equation to solve for acceleration:
Where:
vf = final velocity
vi = initial velocity
t = time
Plug in the given values:
