Derivative Rule [Chain Rule]: $\displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Derivative: $\displaystyle \frac{d}{dx} [e^u]=e^u \cdot u'$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle J(x) = e^{f(x)}$

Step 2: Differentiate

eˣ Derivative [Derivative Rule - Chain Rule]: $\displaystyle J'(x) = \frac{d}{dx}[e^{f(x)}] \cdot \frac{d}{dx}[f(x)]$
Simplify: $\displaystyle J'(x) = f'(x)e^{f(x)}$

Step 3: Evaluate

Substitute in x [Derivative]: $\displaystyle J'(3) = f'(3)e^{f(3)}$
Substitute in function values: $\displaystyle J'(3) = -e^{0}$
Simplify: $\displaystyle J'(3) = -1$

Answer:

#See solution and attached for details

Step-by-step explanation:

Straight line method assumes a gradual depreciation in value of an asset's useful life.

-It's calculated by dividing the difference between an asset's cost and its expected salvage value by the number of years it is expected to be used.

$Dep/yr=(A-Salvage)/n\ \ \ \ \ \ n=15, A=32000\\=(32000-2000)/15\\=2000$

From our calculation, depreciation is $2,000 per year

Accumulated depreciation=8*2000=$16,000

On one side of a football stadium are 30 suites on the circle level. Fourteen of the suites have 24 seats each, and the rest hav

hram777 [196]

The simplest form of a fraction occurs when the numerator and denominator cannot get any smaller (while still being integers)

In the stadium there are 30 suites.

14 suites.............24 seats
16 suites..............18 seats

The suites with 24 seats are 14 out of 30 which can be represented as 14/30.

However, the simplest fraction would be

7*2 7
------- = ------
15*2 15

This is why Tyler is incorrect
