Answer:

x = 20 degrees

Explanation:

With a 20 degree angle on the direct opposite side, it shows that x is also 20 degrees; and the other two angles would be 160 degrees.

Hope this helps :)

When records were first kept (t=0), the population of a rural town was 260 people. During the following years, the population gr
Firdavs [7]

Answer:

(a) The population after 15 years is 2678.

(b)Therefore the population P(t) at any time t>0 is

P(t)= 45t+30 {t^{\frac32}}+260

Step-by-step explanation:

Given that,

The population grew at a rate of

P'(t)=45(1+\sqrt t)

Integrating both sides

\int P'(t) dt=\int 45(1+\sqrt t)dt

\Rightarrow \int P'(t) dt=\int (45+45\sqrt t)dt

\Rightarrow \int P'(t) dt=\int 45\ dt+\int 45\sqrt t\ dt

\Rightarrow P(t)= 45t+45\  \frac{t^{\frac12+1}}{\frac12+1}+c              [ c is integration constant]

\Rightarrow P(t)= 45t+45\  \frac{t^{\frac32}}{\frac32}+c

\Rightarrow P(t)= 45t+45\times\frac 23 \times {t^{\frac32}}+c

\Rightarrow P(t)= 45t+30 {t^{\frac32}}+c

When t=0 , P(0)= 260

\therefore 260= 45\times0+30\times {0^{\frac32}}+c

\Rightarrow c=260

\therefore P(t)= 45t+30 {t^{\frac32}}+260

Therefore the population P(t) at any time t>0 is

P(t)= 45t+30 {t^{\frac32}}+260

To find the population after 15 years, we need to plug t=15 in the above expression.

P(15)=( 45\times 15)+30( {15^{\frac32}})+260

         ≈2678

The population after 15 years is 2678.

$4000 principal earning 6% compounded annually after 5 years
sergij07 [2.7K]
If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90
Please recheck the calculation.
