Given the table below, determine if the data represents a linear or an exponential function and find a possible formula for the

posledela

The answer is C, the function is not following constant change, so not linear, and if it was .1^x, then it would be 1.4 instead of 12.6. So C is correct.

Answer:

$L\left(te^{2t }sin3t\right)=\frac{6s-12}{(s^2-4s+13)^2}$ .

Step-by-step explanation:

If F(s)= L{f(t)}

Then $L\left\{(t^nf(t)\right\}=(-1)^n\frac{\mathrm{d^n}F(s)}{\mathrm{d^n}s}$

$L\left\{te^{2t}sin3t\right\}$

f(t)= $e^{2t}sin3t$

$L\left\{e^{at}sinbt\right\}=\frac{b}{(s-a)^2+b^2}$

Therefore, $L\left\{e^{2t}sin3t\right\}=\frac{3}{(s-2)^2+(3)^2}$

$L\left\{e^{2t}sin3t\right\}=\frac{3}{s^2-4s+13}$

$L\left\{te^{2t}sin3t\right}=-\frac{\mathrm{d}F(s)}{\mathrm{d}s}$

=- $\frac{\mathrm{d}e^{2t}sin3t}{\mathrm{d}s}$

$L\left\{te^{2t}sin3t\right\}$

$=\frac{3(2s-4)}{(s^2-4s+13)^2}$

$L\left\{te^{2t}sin3t\right\}=\frac{6s-12}{(s^2-4s+13)^2}$ .

tatuchka [14]

Answer:

A. 0.083%

Step-by-step explanation:

Total population=60,000

Total infected=600

Percentage of total infected=600/60,000×100

=0.01×100

=1% of the total population

50 people died out of total infected

Percentage of death of total infected=50/600×100

=8.33%

Total death from all causes=110

Percentage of total death from all causes to the total population=110/60,000×100

=0.1833%

Proportionate mortality rate(PMR) of dengue in the population can be calculated as:

Percentage of death from total infected to the total population

=50/60,000×100

=0.0833%

Approximately 0.083%
