During the first decade of the century, the population of a certain city was 145,380 in 2000 and 219,135 in 2010. Find the expon

Likurg_2 [28]

Answer:

The exponential growth function is $P=145380e^{0.04103t}$

Step-by-step explanation:

Given: The population of a certain city was 145,380 in 2000 and 219,135 in 2010.

To find: exponential growth function that models the growth of the city

Solution:

The exponential growth function is given by $P=P_0 e^{kt}$

Here, P denotes total population after time t

$P_0$ denotes initial population

k denotes rate of growth

t denotes time

As $P(0)=145,380$ ,

$145380=P_0e^{0}\\145380=P_0\\P=145380e^{kt}$

As $P(10)=219135$

$219135=145380e^{10k}\\e^{10k}=\frac{219135}{145380}\\=1.507326\\k=\frac{1}{10}\ln (1.507326)\\=0.04103\\\Rightarrow P=145380e^{0.04103t}$

PLS HELP ASAP STUMPED ON THIS ONE!!!!!!! ?/? ÷ 5 = 12/50

Svet_ta [14]

Answer:

6/5 or 1.2

Step-by-step explanation:

you can solve with an equation:

x : 5 = 12 : 50

x = 5 * 12 : 50

x = 6/5 (or 1.2)

or you can solve with an expression

12/50 * 5 = 6/5 (or 1.2)

Alice's backyard is a rectangular piece of property that is twice as long as it is wide. The total area of her yard is 500 m^(2)

Alchen [17]

The approximate width of Alice's backyard is 22.36 in.

Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = 22.360679775 in or 22.36 in
