Let, the time when <span>Jan cough up to Carol = x
We know, Distance = Speed * Time.
So, Equation would be: 2x + 5*2 = 6x
2x + 10 = 6x
6x - 2x = 10
4x = 10
x = 10/4 = 2.5
Distance traveled in that time = 2.5 * 6 = 15 miles
In short, Your Answer would be: 15 miles
Hope this helps!</span>
Answer:
The maximum error in the calculated area of rectangle is 5.4 cm².
Step-by-step explanation:
Given : The length and width of a rectangle are measured as 30 cm and 24 cm, respectively, with an error in measured of at most 0.1 cm in each.
To find : Use differentials to estimate the maximum error in the calculated area of rectangle ?
Solution :
The area of the rectangle is
The derivative of the area is equal to the partial derivative of area w.r.t. length times the change in length plus the partial derivative of area w.r.t. width times the change in width.
i.e.
Here,
Substitute the values,
Therefore, the maximum error in the calculated area of rectangle is 5.4 cm².
