<span>The population of a species of rabbit triples every year. This can be modeled by f(x) = 4(3)^x and f(5) = 972.
The 5 that is found inside the function has a significant meaning.
It represents the population of a species of rabbit every year. It substitutes the variable x.</span>
So what your going to do us to multiple 170 times 7 because your trying to findte mile. You should get 1,120. Then roound to the nearest ten. The answer should be 1,100. If Im wrong pkease comment back and tell me my mistake. Thank You!
Let Lisa's height be x, Ian's be y and Jim's be z
x = 10 + y . . . (1)
y = 14 + z . . . (2)
y + 14 + z + 14 = 170 + x + 14
y + z - x = 170 + 14 - 28 = 156 . . . (3)
From (2), z = y - 14 . . . (4)
Putting (1) and (4) into (3) gives,
y + y - 14 - 10 - y = 156
y = 156 + 24 = 180
Therefore, Ian's height is 180 centimeters
The initial population of the town is 7000, rate of reduction is 3%, thus the function modeling the new population will be given by:
f(t)=7000(0.97)^t
thus since our t=0 is in the year 2010, in the year 2019, t=19. The new population will be:
f(19)=7000(0.97)^19
f(19)=3,924.29
Thus the estimated population will be 3,924.29
you're given all those values, h,k and r, so just plug them in
