Answer:
%
Step-by-step explanation:
Surface area of a human body is given by -

Taking integral on both sides, we get -

Since, the at most error in the surface area of a human body is
%
Substituting this in above equation, we get -
![\frac{dS}{S} \leq [0.425*0.02 + 0.725*0.02]\\\frac{dS}{S} \leq0.023\\](https://tex.z-dn.net/?f=%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq%20%5B0.425%2A0.02%20%2B%200.725%2A0.02%5D%5C%5C%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq0.023%5C%5C)
Thus, the maximum error is surface area is equal to
%
Answer: a = 36 and b = 9
Explanation:
(6x-3)(6x+3)
= 36x² - 18x - 18x - 9
= 36x² - 9
(6x-3)(6x+3) = ax² - b
36x² - 9 = ax² - b
a = 36 and b = 9
Hope it helps!
Answer:
Step-by-step explanation:
44 = 2 * 2 * 11
= 2² *11
Answer:
Step-by-step explanation:
m∠1 = 3 times of m∠2
m∠2 = (1/3) times of ∠1

m∠2 = 24°
Answer:
21
Step-by-step explanation:
I shall change the pictures to letters
a + a + b = 40 --(1)
b - c = 7 --(2)
c + a = 19 --(3)
a - c + b = ?
From (1):
2a + b = 40
b = 40 - 2a --(4)
From (2):
b = 7 + c --(5)
Sub (4) into (5):
40 - 2a = 7 + c
c = 33 - 2a --(6)
Sub (6) into (3):
33 - 2a + a = 19
a = 14
Sub a = 14 into (4) and (6):
b = 40 - 2(14) = 12
c = 33 - 2(14) = 5
therefore, a - c + b = 14 - 5 + 12 = 21
