Use the function below to find F(4) F(x) = 5 * (1/3) ^ x

Inessa05 [86]

The answer for the function F(4) = 5/81

Step-by-step explanation:

The given function is F(x) = 5 * (1/3) ^ x

step 1 :

The x value is given as the input to get the output from F(x)

step 2 :

Here, F(4) means that the x value is x=4

step 3 :

Now, substitute x=4 in the given function F(x)

F(4) = 5 (1/3)^4

=5 (1/81)

F(4) = 5/81

D/dx (28000-50x²-400x)

drek231 [11]

Answer:

$-100x - 400$

Step-by-step explanation:

The derivative of a sum is the sum of the derivatives by the sum rule, and this also extends to differences by the constant multiple rule

$\dfrac{d}{dx}(28000 - 50x^2 - 400x) = \dfrac{d}{dx}(28000) - \dfrac{d}{dx}(50x^2) - \dfrac{d}{dx}(400x)$

By the constant multiple rule, we have

$= \dfrac{d}{dx}(28000) - 50\dfrac{d}{dx}(x^2) - 400\dfrac{d}{dx}(x)$

The derivative of any constant is 0.

The power rule says that for any real number $n$ , $\frac{d}{dx} x^n = nx^{n-1}$ . And note that $x = x^1$ . Thus we have

$= 0 - 50(2)x - 400(1)x^0 = -100x - 400$

since $x^0 = 1$
