N(t) = 25t + 150 for 0< =t< 6, (200 + 80t)/(2 + 0.05t) for t> =8

the number of fish in a pond at time t years is modeled by the function n defined above, where f is a continuous function such that f(0)=80.

a) find limt→[infinity]n(t). explain the meaning of limt→[infinity]n(t) in the context of the problem.

justin bieber ml.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

we are given polynomial 2x^2 +4x +7.

we need to determine the number of roots of the given polynomial using the fundamental theorem of algebra.

a) for the given polynomial 2x^2+4x+7, we have degree =2.

b) let us find the roots of the given polynomial.

2x^2+4x+7= 0

question: the type of image formed by a convex lens is determined by the objects?

answer: it depends on the shape of the lens and the position of the object.

explanation: because if it was not positioned correctly it would have a diffrent image of what you were expecting to see
