Given that the book value of the automobile that was purchased is 30,000 and is to be depreciated for 3 years using MACRS method of depreciation the value of the automobile at the end of the year is 8,640 dollars. This is computed by summing up the depreciation for the firswt 3 years which is equal to 71.2 per cent less 100 then it will be multiply to 30,000.

Given:

Differentiate with respect to x, we get

The given point is (3,9)
Substitute x=3 in the derivative, we get

Hence the slope is 3.

Given:

Differentiate with respect to x, we get

The given point is (0,4)
Substitute x=0 in the derivative, we get

Hence the slope is 0.
Answer:
The hypotenuse of the triangle measures 13 inches.
Step-by-step explanation:
Since the Pythagorean theorem states that in any right triangle the lengths of the three sides are related by the equation A ^ 2 + B ^ 2 = C ^ 2, to determine the length of the hypotenuse in a right thangle with legs 5 inches and 12 inches the following calculation should be performed:
5 ^ 2 + 12 ^ 2 = X ^ 2
25 + 144 = X ^ 2
√169 = X
13 = X
Therefore, the hypotenuse of the triangle measures 13 inches.
He messed up in the beginning with the 4.
It's supposed to be
(3 - -4)
(3 + 4)
and not
(3-4)
That's where he messed up.
I find it interesting how he uses Xa Ya and Xb Yb. In my school we use X1 Y1 and X2 Y2.
