Study. also, i would leave the answer there, but it says i need 20 words to answer so thats why i included this extra bit, but yeah just study.
You would have to take 6336 steps because 63360 inches is one mile and that divided by 10 is 6336
Answer:
f(x) = - 8
Explanation:
The given function is
f(x) =2x^2 -4x -6
The first step is to find the derivative of the function. Recall, if
y = ax^b
y' = abx^(b - 1)
Thus,
f'(x) = 4x - 4
We would equate f'(x) to zero and solve for x. We have
4x - 4 = 0
4x = 4
x = 4/4
x = 1
We would substitute x = 1 into the original function and solve for f(x) or y. It becomes
f(1) =2(1)^2 -4(1) - 6 = 2 - 4 - 6
f(1) = - 8
Thus, the minimum value is f(x) = - 8
Answer:
24 Bricks.
Step-by-step explanation:
We know the radius is 6 feet and that the diameter is twice that.
We also know the radius is 12 'bricks' in length.
If we divide both numbers by 12, we get that 1 'brick' is half a foot.
Since that's the radius and we want the diameter, we multiply the radius by 2 to get the diameter.
This results in 12 feet, or 24 'bricks'.
