The population of a town grows exponentially. After 1 year, the population is 34,560. After 2 years, the population is 37,325. W
Vladimir [108]
Exponential growth has the form:

F=Ir^t, F=final amount, I=initial amount, r=rate, t=time.

First let's solve for the rate, r, using the points provided...

37325/34560=(Ir^2)/(Ir^1)

r≈1.08  

Now find the initial amount...

34560=I(1.08)^1

I=32000 so now we have the entire equation, using x and y...

y=32000(1.08)^x

Gnesinka [82]

Answer:

<em>36%</em>

Step-by-step explanation:

"8 kg of mixed nuts containing 26% peanuts"

weight of peanuts: 26% * 8 kg = 0.26 * 8 kg = 2.08 kg

"5 kg ... that contain 52% peanuts"

weight of peanuts: 52% * 5 kg = 0.52 * 5 kg = 2.6 kg

Total weight of peanuts: 2.08 kg + 2.6 kg = 4.68 kg

Total weight of mixed nuts: 8 kg + 5 kg

percent of peanuts: (4.68 kg)/(13 kg) * 100% = 36%

Answer:

<em>R</em><em>M</em>79 608.51

Step-by-step explanation:

First year,

<em>RM</em>505 050.00×5%=<em>RM</em>505 050.00×5/100

=<em>RM</em>25 252.50

second year,

(<em>RM</em>505 050.00+<em>R</em><em>M</em>25 252.50)×5%=<em>RM</em>530 302.50×5/100

=<em>RM</em>26 515.13

third year,

(<em>R</em><em>M</em>530 302.50+<em>R</em><em>M</em>26 515.13)×5%=<em>R</em><em>M</em>556817.63×5/100

=<em>R</em><em>M</em>27840.88

three years interest,

<em>RM</em>25 252.50+<em>RM</em>26 515.13+<em>RM</em>27840.88=<em>RM</em>79608.51
