Answer:
the answer is the first one!
because if x=-3 we know that |x|=|-3|=3
Answer:
11 feet
Step-by-step explanation:
All the sides of a square are equal
the area of a square = length²
121 ft² = length²
to determine the length find the square root of the area, 121
√121 = 11 feet
H(t) = t^(3/4) - 3t^(1/4)
The critical points can be evaluated by taking the first derivative and equating to 0.
h'(t) = 3 / t^(1/4) - 3 / 4t^(3/4)
3 / (4t^(3/4)) = 3 / t^(1/4)
4t^(3/4) = t^(1/4)
4 = 1/√t
t = 1/16, t = -1/16
Answer: 
or 
Step-by-step explanation:
You can use the following work-rate formula:
In this case let be 
the time it takes for Natalie to pick 40 bushels, 
the time it takes for Mary to pick 40 bushels and 
the time it takes to pick 40 bushels if they work together.
Based on the information given in the exercise, you can identify that:
Then, knowing this values, you need to substitute them into the formula:
Finally, you must solve for "t" in order to find its value.
The result is:
Since 
:
Therefore it would take 5 hours and 44 minutes to pick 40 bushels if they worked together.
