Answer:
MArginal productivity:
We can interpret this as he will reduce his time an <em>additional </em>0.0002 seconds for every <em>additional </em>yard he trains.
Step-by-step explanation:
The marginal productivy is the instant rate of change in the result for an increase in one unit of a factor.
In this case, the productivity is the time he last in the 100-yard. The factor is the amount of yards he train per week.
The marginal productivity can be expressed as:
where dt is the variation in time and dL is the variation in training yards.
We can not derive the function because it is not defined, but we can approximate with the last two points given:
Then we can interpret this as he will reduce his time an <em>additional </em>0.0002 seconds for every <em>additional </em>yard he trains.
This is an approximation that is valid in the interval of 60,000 to 70,000 yards of training.
Answer:
A.)D23
Step-by-step explanation:
ANSWER: x=$125 to make it equal to 7,000
working the problem:
7,000-1,250=5,750
5,750÷46=125
1,250+46×125 is greater than or equal to 7,000
Answer:
175 minutes
$43.75
Step-by-step explanation:
Let y = total cost
x = minutes
Plan A charges $0.17 per minute, so we multiply x by 0.17 like this: 0.17x
$14 is also already added on
y = 0.17x + 14
Plan B charges $0.13 per minute, so we multiply x by 0.13 like this: 0.13x
$21 is already added on
y = 0.13x + 21
Now we have to find where both x'es in both equations are the same
0.17x + 14 = 0.13x + 21
First, subtract 14 from both sides
0.17x + 14 = 0.13x + 21
- 14 - 14
0.17x = 0.13x + 7
Then subtract 0.13x from both sides
0.17x = 0.13x + 7
-0.13x -0.13x
0.04x = 7
Finally, divide both sides by 0.04
0.04x/0.04 = 7/0.04
x = 175
175 minutes of phone calls will need to be made on both plans for their costs to equal.
To find the price of those plans, we need to plug in the new x in one of the starting equations. We'll use the equation from Plan A.
y = 0.17(175) + 14
y = 29.75 + 14
y = 43.75
If both costs of the plans were to equal, they would cost $43.75
