[25 POINTS] The approximate change in the value of f(x) = sqrt(2(x-1)) at x = 3 using differentials with dx = 0.01 is

otez555 [7]

Answer:

$\frac{1}{200}$

Step-by-step explanation:

<u>Find the derivative of the function when x=3</u>

<u /> $y=\sqrt{2(x-1)}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(x-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(3-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(2)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{4}}$

$\frac{dy}{dx}=\frac{1}{2}$

Since the change in the value of the function is $dy$ and we know that the change in x is $dx=0.01$ , then we have:

$\frac{dy}{dx}=\frac{1}{2}$

$dy=\frac{1}{2}dx$

$dy=\frac{1}{2}(0.01)$

$dy=\frac{1}{200}$

Therefore, the 2nd option is correct

Plssssssssssssssssssssssssssssssssssssssssssssssss

julia-pushkina [17]

Step-by-step explanation:

Total weight of all 3 books = 2 7/16 + 1 7/8 + 1/2

Finding the common denominator,

2 7/16 = 39/16

1 7/8 = 15/8 = 30/16

1/2 = 8/16

Total = 39/16 + 30/16 + 8/16

= 77/16 = 4 13/16 pounds = 5 pounds

Total is less than 6 pounds. So, Gina can ship all 3 books.

Calculate the value of x.

mars1129 [50]

Answer:

49.2°

Step-by-step explanation:

To solve for x you'll need to find the cosine of x°.

To find the cosine you will need to divide the adjacent side to it by the hypotenuse.

cos x°= $\frac{17}{26}$

Using a calculator to solve you'll get that x ≈ 49.2°
