Answer:
a = 5
Step-by-step explanation:
Answer: 3/10
Step-by-step explanation:
Take the derivative of
to get
. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:

There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value
8 is the answer!
Turn 1/4 into a decimal then divide 2 by .25
Answer: 11 games
Step-by-step explanation:
With $15,
First step, subtract cost of admission= $5
$15 - $5 = $10
If one game costs $0.85
× games = $10/ $0.85
=11.7
The maximum number of games he can play is 11.
I hope this is clear.
B=-6 is the correct answer
