Answer:
If you want to know what b is then it is 16
Step-by-step explanation:
38 + b = 54
54- 38 = 16
38 + 16= 54

Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation
![{f\left( x \right) \approx L\left( x \right) }={ f\left( a \right) + f^\prime\left( a \right)\left( {x - a} \right).}](https://tex.z-dn.net/?f=%7Bf%5Cleft%28%20x%20%5Cright%29%20%5Capprox%20L%5Cleft%28%20x%20%5Cright%29%20%7D%3D%7B%20f%5Cleft%28%20a%20%5Cright%29%20%2B%20f%5E%5Cprime%5Cleft%28%20a%20%5Cright%29%5Cleft%28%20%7Bx%20-%20a%7D%20%5Cright%29.%7D)
Linear approximation is a good way to approximate values of
as long as you stay close to the point
, but the farther you get from
, the worse your approximation.
We know that,
![a=2\\f(2) = 5\\f'(x) = \sqrt{3x-1}](https://tex.z-dn.net/?f=a%3D2%5C%5Cf%282%29%20%3D%205%5C%5Cf%27%28x%29%20%3D%20%5Csqrt%7B3x-1%7D)
Next, we need to plug in the known values and calculate the value of
:
![{L\left( x \right) = f\left( 2 \right) + f^\prime\left( 2 \right)\left( {x - 2} \right) }=5+\sqrt{3(2)-1}(x-2) =5+\sqrt{5}(x-2)](https://tex.z-dn.net/?f=%7BL%5Cleft%28%20x%20%5Cright%29%20%3D%20f%5Cleft%28%202%20%5Cright%29%20%2B%20f%5E%5Cprime%5Cleft%28%202%20%5Cright%29%5Cleft%28%20%7Bx%20-%202%7D%20%5Cright%29%20%7D%3D5%2B%5Csqrt%7B3%282%29-1%7D%28x-2%29%20%3D5%2B%5Csqrt%7B5%7D%28x-2%29)
Then
.
