Step-by-step explanation:
12/23 ≈ $0.52
Answer: 120 seconds
Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.
f'(x)=(-3x^2 + 12x)'=-6x+12=0
x=2
When x is 2, the function will reach its maximum value.
f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12
The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.
You have to distribute the parentheses first. Since there is a negative sign in front of the parentheses, it counts as a negative 1. After you distribute you should get: -5+6x=20x+12, but that is not your final answer. After you add like terms: 17x=-17. Divide 17 on both sides: x=-1. X=-1 is your final answer.
The answer is 2 hopefully this helped
Answer:
6 6/25
Step-by-step explanation:
6 24/100 = 6 (6·4)/(25·4) = 6 6/25
_____
You reduce a fraction by removing the common factors from numerator and denominator. Of course, you know that 0.24 is twenty-four hundredths, also written as 24/100.
