Answer:

Y=5x

Step-by-step explanation:

Y=mx+b, or y=rise/run+starting value

as there is no starting value, we would simply add no variable

rise/run in this equation would 5/1 because when it rises 5, it goes right 1, simplifying that would be 5

A given field mouse population satisfies the differential equation dp/dt=.4p-450 where p is the number of mice and t is the time

Flura [38]

Answer:

a) 7.78 months

b) 1116

Step-by-step explanation:

Given -

$\frac{dP}{dt} = 0.4p-450$

Integrating the above equation with respect to time, we get -

$\int\ \frac{dP}{0.4p-450} = \int\ dt\\$

let us define new variable x

$x = 0.4p - 450 \\dx = 0.4 dy$

substituting these values in above integral equation, we get -

$\frac{1}{0.4} \int\ \frac{dx}{x} = \int\ dt\\ln x = 0.4 t + C\\x = ce^{0.4t}$

$P (t) = \frac{C}{0.4} e^{0.4t} +1125\\$

at t = 0, P (0) = 1075, using this condition, we get -

$\frac{c}{0.4} = -50\\P(t) = 50 e^{0.4t} +1125 \\t = 7.78\\P(0) = 1125 - \frac{1125}{e^{4.8}} = 1116$

Simplify the expression completely. x squared over x to the power of 6

andrezito [222]

$\frac{{x}^{2} }{ {x}^{6} }$
using one of the law of indices:
${x}^{2 -6} \\ = {x}^{ - 4}$
which can also be written as
$\frac{1}{ {x}^{4} }$
