Answer:

x = 12

Step-by-step explanation:

(7x+4)+(2x+5)+(5x+3) = 180

so if you take out the brackets it would be:

7x+4+2x+5+5x+3 = 180

Then you add the similar variables together which would look like:

14x+12=180

Take away 12 from both sides

14x = 180 - 12

14x = 168

Divide 14 from both sides

x = 168/14

x = 12

Answer:

x=12

Step-by-step explanation:

2x+5+5x+3+7x+4=180

14x+12=180

180-12=168

14x=168

x=12

A particular country's exports of goods are increasing exponentially. The value of the exports, t years after 2008, can be ap

Alex_Xolod [135]

Answer:

a) For 2008 we have that t = 2008-2008 = 0 and we have:

$V(0)= 1.4e^{0.039*0}= 1.4$

For 2022 we have that t = 2022-2008=14 and if we replace we got:

$V(12) = 1.4 e^{0.039*14}=2.417$

b) $2.8 = 1.4 e^{0.039 t}$

We can divide both sides by 1.4 and we got:

$2 = e^{0.039 t}$

Now natural log on both sides:

$ln (2) = 0.039 t$

$t = \frac{ln(2)}{0.039}= 17.77 years$

Step-by-step explanation:

For this case we have the following model given:

$V(t) = 1.4 e^{0.039 t}$

Where V represent the exports of goods and the the number of years after 2008.

Part a

Estimate the value of the country's exports in 2008 and 2022

For 2008 we have that t = 2008-2008 = 0 and we have:

$V(0)= 1.4e^{0.039*0}= 1.4$

For 2022 we have that t = 2022-2008=14 and if we replace we got:

$V(12) = 1.4 e^{0.039*14}=2.417$

Part b

What is the doubling time for the value of the country's exports.

For this case we can set up the following condition:

$2.8 = 1.4 e^{0.039 t}$

We can divide both sides by 1.4 and we got:

$2 = e^{0.039 t}$

Now natural log on both sides:

$ln (2) = 0.039 t$

$t = \frac{ln(2)}{0.039}= 17.77 years$
