1/2(18t)+12t(9)-12 = 9t+108t-12 = 117t-12 = 39t-4
Answer:
See below
Step-by-step explanation:
<em>Quadratic function is in general form of:</em>
- <em>y = ax^2 + bx + c</em>
<em>The function has a minimum if a > 0 and maximum if a < 0</em>
<em>The minimum or maximum point is a vertex of the graph</em>
- <em>A vertex is the point x = -b/2a</em>
<em>When b = 0, the min or max point equals to value of c.</em>
- 33. It has maximum of -1
- 34. It has minimum of 7
- 35. It has minimum at x = - 8/4 = -2
f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
- 36. It has maximum at x = -18/2(-3)= 3
g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
- 37. It has minimum at x = - 6/(2*3/2) = - 2
f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

Caleb has paid for 24 months of service.
Step-by-step explanation:
<u>1) based on what is written in this problem, setup an equation.</u>
26x + 215 = 839
<u>2) Subtract 215 from both sides.</u>
839 - 215 = 624
<u>3) 26x = 624</u>
Divide both sides by 26
624/26 = 24
