aleksandr82 [10.1K]

Given

y=11(\frac{1}{2})^{\frac{t}{30}}

When t = 80

We substitute for t

y=11(\frac{1}{2})\frac{}{}^{\frac{80}{30}}

Simplify

y=11(\frac{1}{2})^{\frac{8}{3}}

Simplify further

y=1.732g

Israel added $120 to his savings. This added amount represents 1/6 of his total savings. If s represents the total savings, whic
oee [108]

Calculista Ambitious

the correct question in the attached figure


Let

s----------> total savings


case a) Israel added $80 to his savings


we know that

80=(1/8)*s-------> multiply by 8 both sides------> s=$640


the answer case a) is

the equation is 

80=(1/8)*s


case b) Israel added $120 to his savings


we know that

120=(1/8)*s-------> multiply by 8 both sides------> s=$960


the answer case b) is

the equation is 

120=(1/8)*s

The growth of a city is described by the population functionwhereis the initial population of the city, t is the time in years,
mamaluj [8]

Complete question:

The growth of a city is described by the population function p(t) = P0e^kt where P0 is the initial population of the city, t is the time in years, and k is a constant. If the population of the city atis 19,000 and the population of the city atis 23,000, which is the nearest approximation to the population of the city at

Answer:

27,800

Step-by-step explanation:

We need to obtain the initial population(P0) and constant value (k)

Population function : p(t) = P0e^kt

At t = 0, population = 19,000

19,000 = P0e^(k*0)

19,000 = P0 * e^0

19000 = P0 * 1

19000 = P0

Hence, initial population = 19,000

At t = 3; population = 23,000

23,000 = 19000e^(k*3)

23000 = 19000 * e^3k

e^3k = 23000/ 19000

e^3k = 1.2105263

Take the ln

3k = ln(1.2105263)

k = 0.1910552 / 3

k = 0.0636850

At t = 6

p(t) = P0e^kt

p(6) = 19000 * e^(0.0636850 * 6)

P(6) = 19000 * e^0.3821104

P(6) = 19000 * 1.4653739

P(6) = 27842.104

27,800 ( nearest whole number)
