The number of bacteria in a refrigerated food product is given by N ( T ) = 27 T 2 − 180 T + 100 N(T)=27T2-180T+100, 7 < T &l
NeX [460]

Answer:

N(T(t))=432t^2-374.4t-118.88

The number of Bactria after 5.8 hours is 12242.

Step-by-step explanation:

The number of bacteria in a refrigerated food product is given by

N(T)=27T^2-180T+100

where, T is the temperature of the food.

When the food is removed from the refrigerator, then the temperature is given by

T(t)=4t+1.6

We need to find the composite function N(T(t)).

N(T(t))=N(4t+1.6)

N(T(t))=27(4t+1.6)^2-180(4t+1.6)+100

N(T(t))=432t^2+345.6t+69.12-720t-288+100

N(T(t))=432t^2-374.4t-118.88

where N(T(t)) is the number of bacteria after t hours.

Substitute t=5.8 in the above function.

N(T(5.8))=432(5.8)^2-374.4(5.8)-118.88

N(T(5.8))=14532.48-2290.4

N(T(5.8))=12242.08

N(T(5.8))\approx 12242

Therefore, the number of Bactria after 5.8 hours is 12242.

What is the solution to the equation 4x-6= 10x-3?
Lelechka [254]

Answer:

To solve this equation we need to get x by itself.

4x-6=10x-3, (the first step would be adding 6 to both sides.)

4x=10x+3 (the next step is the subtract ten from both sides.)

-6x=3 (Last step is the divide both sides by -6.)

x=-1/2

Hope this helps ;)

Simplify the expression:<br><br> 7(1 + 2g) =
lesya692 [45]
7+14g because your multiplying seven by the parenthesis and because you don’t know the value of g you have to keep it as 2g times 7 which would be 14g
