Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] $ y =
Advocard [28]

Answer:

The answer is "\frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}".

Step-by-step explanation:

Given:

y = e^{{\color{\red}5}\sqrt{x}}

let

\to  t= 5\sqrt{x}\\\\\frac{dt}{dx}= 5 \frac{1}{2\sqrt{x}}\\\\\frac{dt}{dx}=  \frac{5}{2\sqrt{x}}\\\\

and

\to y=e^t\\\\\to \frac{dy}{dt}=e^t\\

\to \frac{dy}{dt}=e^{5\sqrt{x} }\\

So,

\to \frac{dy}{dx}=  \frac{dy}{dt} \times \frac{dt}{dx}

         =e^{5\sqrt{x} }\times  \frac{5}{2\sqrt{x}}\\\\= \frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}

OR

\to g(x) = 5\sqrt{x} \\\\\to f(x) = e^{(x)}\\\\

Derivate:  

\to f''g' = \frac{e^{(5\sqrt{x})}5}{(2\sqrt{x})}

Tatesville had x inches of rainfall in April, (x + 1.3) inches of rainfall in May, and (2x + 0.5) inches in June. If x=2 inches,
inna [77]

Answer: 9.8 inches

Step-by-step explanation:

Since x = 2 inches

Rainfall in April = x inches = 2 inches

Rainfall in May = x + 1.3 = 2 + 1.3 = 3.3 inches

Rainfall in June = 2x + 0.5 = 2(2) + 0.5 = 4.5

Total rainfall = 2 + 3.3 + 4.5 = 9.8 inches
