Answer:


Step-by-step explanation:
Given

Require
Solving (a):

Subtract 24 from both sides


Divide both sides by 2



Solving (b):
Substitute 330 for P un the expression in (1)

Evaluate the bracket


<em>Question c; seem irrelevant</em>
Derive the equation and equate the derivative to zero.
dan/dt = -2n + 6 = 0
The value of n in the equation is 3. We substitute 3 to the original equation,
an = -(3)² + 6(3) - 7 = 2
The answer to this item is letter B.
A = 30
B = 41
C = 70
A < B + C
30 < 41+70 ==> 30 < 111 (TRUE)
B < A + C ==>
41 < 30 + 70 ==> 41 < 100 (TRUE)
C < A+B
70 < 30 + 41 ==> 70 < 71 (TRUE)
Yes, can!
