By completing the square: x²-8x+19 = (x-4)²-16+19 = (x-4)²+3 so minimum point = (4,3)
By calculus: f'(x) = 2x-8. (minimum point occurs when f'(x)=0 therefore)
2x-8 = 0 means x=4 and the corresponding y value is 3.
The minimum value of this function (y) is 3 and this occurs when x = 4.
rad 128 can be broke into 64*2
square root of 64 is 8, times -5,
which leaves -40rad2
Answer:
37
Step-by-step explanation:
Highest - lowest = range
64-27= 37
360=24%0f x
360=24/100*x
360*100=24x
36000/24=x
therefore, x=1500......
The answer would be C. Mike can drive at the most 500 miles.
$200 - the rent for the week ($125)= $75
$75/($.15) the money per mile
500 miles.
Hope This Helps!
