How do you solve 2i and 2ii

natta225 [31]

Answer:

15 and 21

Step-by-step explanation:

Given the n th term formula

T = 2n + 5

To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula

$T_{5}$ = (2 × 5) + 5 = 10 + 5 = 15

$T_{8}$ = (2 × 8) + 5 = 16 + 5 = 21

Triss [41]

Answer:

Step-by-step explanation:

The midsegment AC is half the sum of the parallel bases, that is

AC = $\frac{DF+EB}{2}$ , then

x = $\frac{13+9}{2}$ = $\frac{22}{2}$ = 11 → D

The current (2015) population of Eugene is approximately 155,000 people. a) If the population growth rate remains at 4% per year

Olegator [25]

$\bf \textit{Amount of Population Growth}\\\\
A=Ie^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &500,000\\
I=\textit{initial amount}\to &155,000\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=\textit{elapsed time}\\
\end{cases}$

$\bf 500000=155000e^{0.04t}\implies \cfrac{500000}{155000}=e^{0.04t}\implies \cfrac{100}{31}=e^{0.04t}
\\\\\\
\textit{now, we take \underline{ln} to both sides}
\\\\\\
ln\left( \frac{100}{31}\right)=ln(e^{0.04t})\implies ln\left( \frac{100}{31}\right)=0.04t\implies \cfrac{ln\left( \frac{100}{31}\right)}{0.04}=t$

so it will have 500,000 approximately "t" years after 2015.
