Hi there, first we change the mixed numbers into improper fractions, 9 5/9=86/9 and 6 5/6=41/6. Second, we solve the problem now. 86*6-41*9÷9*6, 516-369/54=147/54. Third, we simplify 147/54 into 49/18. Fourth, we make 147/54 into a mixed number. 147/54 as a mixed number is 2 13/18
Answer:
(0, inf)
Step-by-step explanation:
The average rate of change of a function is related to it's first derivative. When the first derivative is positive, the average rate of change is positive, which means that the function is crescent.
Now, when the first derivative is negative, the average rate of change will be negative too, and the function is going to be decrescent.
In your function.
We have: f'(x) = 2x
2x > 0 when x > 0. So when x > 0 the average rate of change of your function is positive, and it's values increases as the time increases. When x < 0, the average rate of change is negative, so, as the time increases, the values of f decrease.
You can use a graphic tool to plot f and visualize this better.
48 divide by 4 sides = 12
12 x 12 = 144cm squared
Answer:
Step-by-step explanation:
(0, 4) (2, 0)
(0-4)/(2-0) = -4/2 = -2
y - 4 = -2(x - 0)
y - 4 = -2x + 0
y = -2x + 4
