Answer:
-3
Step-by-step explanation:
simplify the expression
Answer:
A, C, D
Step-by-step explanation:
1) A triangular pyramid has the same number of faces as vertices: 5
2) C - The sum is 5 + 6 =11
3) D - Euler's Formula tells us that if we add the number of faces and vertices together and then subtract the number of edges, we will get 2 as our answer.
Answer:
Time for bacteria count reaching 8019: t = 2.543 hours
Step-by-step explanation:
To find the composite function N(T(t)), we just need to use the value of T(t) for each T in the function N(T). So we have that:
Now, to find the time when the bacteria count reaches 8019, we just need to use N(T(t)) = 8019 and then find the value of t:
Solving this quadratic equation, we have that t = 2.543 hours, so that is the time needed to the bacteria count reaching 8019.
