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.
Bonjour,
answer ≈ 522.92
working
A= 2πrh+2πr^2
=2 x π x 4 x 18+2 x π x 4^2
≈552.92031
The value of f(5) is
Step-by-step explanation:
The function is
To find substitute in
Multiplying the terms, we get,
Adding the terms, we get,
Thus, the value of is
Answer:
4 C, 5 C
Step-by-step explanation:
4) Sum of all candies = 14
Total number of cherry candies = 5
probability of not getting a cherry candy = 14-5 / 14 = 9/14
5) Number of supporters for Lyshon = 14
Total number of supporters = 100
Probability that a student chosen at random will vote vote for lyshon =
14/100 = 7/50
So, if the discount was 5%, then the sale prize was equal to 95% of the original prize
so 68.40=0.95*x
we divide both sides by 0.95. Let;s start by multiplying them by 100:
6840=95*x
divide by 5 both sides:
1368=19x
now divide by 19
72=x
so the original prize was 72.
