A population of insects increases at a rate 230 + 8t + 0.9t2 insects per day (t in days). Find the insect population after 6 day

____ [38]

Answer:

The insect population after 6 days is of 1639 insects.

Step-by-step explanation:

A population of insects increases at a rate 230 + 8t + 0.9t2 insects per day

This means that $r(t) = 230 + 8t + 0.9t^2$

The population of insects after x days is given by:

$P(t) = \int_{0}^{x}r(t)dt$

$P(x) = \int_{0}^{x} (230 + 8t + 0.9t^2)$

$P(x) = 230t + 4t^2 + 0.3t^3 + K|_{0}^{x}$

$P(x) = 230x + 4x^2 + 0.3x^3 + K$

In which K is the initital population(which is 50). So

$P(x) = 230x + 4x^2 + 0.3x^3 + 50$

After 6 days:

$P(6) = 230*6 + 4*6^2 + 0.3*6^3 + 50 = 1638.8$

Rounding to the nearest insect, 1639

The insect population after 6 days is of 1639 insects.

Temperature in degrees Fahrenheit can be converted into degrees Celsius using the formula C=5(F-32)/9

aksik [14]

Answer:

F= (9C+160)/5

Step-by-step explanation:

C=5(F-32)/9

make F the subject of the formula= isolate F

5(F-32)=9C

5F-160=9C

5F=9C+160

F= (9C+160)/5

check: a, b, c are all positive integers (a=9, b=160, c=5)
