Answer: George needs to work 12 hours to have enough money to buy the bicycle.
Step-by-step explanation
Needs $140
Saved $44
Makes $8hr
Step One: Make an equation
8h + 44 = 140
Step Two: Solve for h
8h + 44 = 140
-subtract 44 on both sides'
8h = 96
-divide 8 on both sides
h = 12
Step Three: Check your work
8h + 44 = 140
8(12) + 44 = 140
96 + 44 = 140
140 = 140

integrating the values by parts:
Therefore, the moment value generating by the function is
In point b:
Using formula:
form point (a):
Differentiating the value with respect of t
when
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
