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.

Answer: 363
Step-by-step explanation:
The common difference is 7, so the explicit formula is
.
Substituting in n=66,

Quantity is the amount of something you have. Quality is whether the product is good or long-lasting
