Compute Δy and dy for the given values of x and dx = Δx. (Round your answers to three decimal places.) y = ex, x = 0, Δx = 0.4

kobusy [5.1K]

Answer:

0.492

Step-by-step explanation:

According to the given situation, the calculation of Δy and dy is shown below:-

$y = e^x, x = o, \Delta x = 0.6$

$dy = f'(x) = e^x$

$dy = e^x dx$

$= e^x (0.4)$

$dy = 0.4e^x$

$\Delta y = f(0.4) - f(0)$

$= e^{0.4} - e^0$

Now we use the scientific calculator or spreadsheet to determine the exponential value

= 1.491824698 - 1

= 0.491824698

= 0.492

Therefore for computing the Δy and dy we simply applied the above formula.

Hence, the answer is 0.4918

julsineya [31]

Answer:

Step-by-step explanation:

The height of the television is 40 inches and the length is 71.5 inches.

Part A

The part of the right angle triangle that you have been given are the legs which are also the opposite and adjacent sides. You are looking for the hypotenuse

Part B

The Pythagorean theorem is expressed as

Hypotenuse² = opposite side² + adjacent side²

The equation becomes

Hypotenuse² = 40² + 71.5²

Part C

Length ² = 1600 + 5112.25

Length ² = 6712.25

Length = √6712.25

Length = 81.9 inches

Part D

The size of the television is 82 inches
