Answer:

Step 1 is wrong

Step-by-step explanation:

$\frac{1}{4} r+ 2 = 10$

$\frac{r}{4} + 2 = 10$

$\frac{r}{4} = 10 - 2$

$\frac{r}{4} = 8$

$r = 8 \times 2$

$r = 32$

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 $P(10)=219135$

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

Solve the absolute value inequality |x+9| > 3

Studentka2010 [4]

Answer:

x>−6,x<−12

Step-by-step explanation:

Break down the problem into these 2 equations.

x+9>3x+9>3

-(x+9)>3−(x+9)>3

Solve the 1st equation: x+9>3x+9>3.

x>-6x>−6

3 Solve the 2nd equation: -(x+9)>3−(x+9)>3.

x<-12x<−12

Collect all solutions.

x>-6,x<-12x>−6,x<−12

Mary planted 5/8 rows of beans and 8/9 rows of carrots in a garden. In total,how many rows of vegetables did Mary plant?

kupik [55]

Rows of beans = 5/8
Rows of carrots = 8/9

Total number of rows = 5/8 + 8/9
= (45 + 64)/72
= 109/72
