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:
<u>Options B and D</u>
Step-by-step explanation:
6x² + x - 1 = 0
6x² + 3x - 2x - 1 = 0
3x(2x + 1) - 1(2x + 1) = 0
(3x - 1)(2x + 1)
x = 1/3 and -1/2
<u>Options B and D</u>
Answer:
f(x) = -x -1
Step-by-step explanation:
You can make the correct choice by seeing which equation works for the first line of the table.
f(-1) = -(-1) -1 = 0 . . . . . the first equation works
f(-1) = -(-1) +1 = 2 . . . not zero
f(-1) = -1 -1 = -2 . . . not zero
f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)
X varies directly as y
x = ky
3 = 2k
k =

when x =9
9 =

y

= y
∴y = 6
