Local wildlife experts have begun to track the population of trout in their area. the function f represents the approximate population of trout in sky lake, and the function g represents the approximate population of trout in lake cyan, where t is the number of months since experts began tracking the populations.

f(t) = 1.5t + 50

g(t) = 0.1t^2 - 4t + 70

find the expression that describes the total trout population in the area after t months, f(t) + g(t).

a. 0.1t^2 + 5.5t +120

b. 0.1t^2 - 5.5t +120

c. 0.1t^2 - 2.5t + 120

d. 0.1t^2 + 2.5t + 120

Option C.

Step-by-step explanation:

We know that

f(t) = 1.5t + 50

represents the approximate population of trout in Sky Lake

And

g(t) = 0.1t^2 - 4t + 70

represents the approximate population of trout in Lake Cyan

The total trout population in the area is described as

f(t) + g(t)

f(t) + g(t) =  [1.5t + 50] + [0.1t^2 - 4t + 70]

f(t) + g(t) =  [1.5t + 50+ 0.1t^2 - 4t + 70]

f(t) + g(t) =  [0.1t^2 -2.5t + 120]

f(t) + g(t) =  0.1t^2 -2.5t + 120

Option C.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
