The dimensions would be 2 by 3 because 15 divided by 5 would be there and 10 divided by 5 would be 2 so the final answer would be 2 by 3 :)

The population of a certain species of insects increases exponentially according to the model, P(0) = 952e0.12t where P is the n

NeX [460]

Answer:

A) 952 insects are in the original colony

B) 10494 insects are in the colony after 20 weeks

C) 25 weeks

Explanations:

The model representing the population of the species of insects

$P(t)=952e^{0.12t}$

An exponential growth is of the form:

$P(t)=P_0e^{kt}$

where P₀ is the original population

t is the time taken in weeks

Comparing the two equations:

$P_0=\text{ 952}$

952 insects are in the original colony

B. The number of insects that will be in the colony after 20 weeks

Substituting t = 20 into the function given

$\begin{gathered} P=952e^{0.12(20)} \\ \text{P = }10494 \end{gathered}$

C) If the population, P = 20000

$\begin{gathered} 20000=952e^{0.12t} \\ e^{0.12t}=\text{ }\frac{20000}{952} \\ e^{0.12t}=21.008 \\ 0.12t\text{ = ln(21.008)} \\ 0.12t\text{ = }3.04 \\ t\text{ = }\frac{3.04}{0.12} \\ t\text{ = }25 \end{gathered}$

On Wednesday, mr. miles walked and ran 9/10 of the trail. Then he walked 1\8 of the trail back and stopped to rest. What fractio

valentinak56 [21]

Answer:

31/40 of the trail

Step-by-step explanation:

he completed 9/10 of the trail (or 72/80 because 9*8 is 72)

He went back 1/8 of the trail (or 10/80 because 1*10 is 10)

72-10 is 62

he went 62/80, simplified is 31/40 of the trail

Given that x^2+y^2=9 and xy=5, find the value of (x - y)^2.

Ede4ka [16]

Answer:

$(x -y)^2 = -1$

Step-by-step explanation:

$(x - y)^2 = x^2 + y^2 - 2xy$

$= (x^2 + y^2 ) - 2(xy)\\\\=(9) - 2( 5)\\\\= 9 - 10 \\\\ = -1$
