Use substitution
Plug in 5x for y
5x = 2x - 15
Subtract 2x
3x = -15
Divide by 3
x = -5, y = -25
Solution: (-5, -25)

Consider the function g(x) = (x-e)^3e^-(x-e). Find all critical points and points of inflection (x, g(x)) of the function g.

Elden [556K]

Answer:

The answer is " $cirtical\ points \ (x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})$ "

Step-by-step explanation:

Given:

$g(x) = (x-e)^3e^{-(x-e)}$

Find critical points:

$g(x) = (x-e)^3e^{(e-x)}$

differentiate the value with respect of x:

$\to g'(x)= (x-e)^3 \frac{d}{dx}e^{e-r} +e^{e-r} \frac{d}{dx}(x-e)^3=(x-e)^2 e^{(e-x)} [-x+e+3]$

critical points $g'(x)=0$

$\to (x-e)^2 e^{(e-x)} [e+3-x]=0\\\\\to e^{(e-x)}\neq 0 \\\\\to (x-e)^2=0\\\\ \to [e+3-x]=0\\\\\to x=e\\\\\to x=e+3\\\\\to x= e,e+3$

So,

The critical points of $(x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})$

The algebraic expression 0.07d^3/2 describes the duration of a storm, in hours, whose diameter is d miles. use a calculator to d

Shkiper50 [21]

Answer:

1.30 hours

Step-by-step explanation:

Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...

duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression

= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)

= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication

≈ 1.30 . . . . rounded to hundredth

The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

___

With a suitable calculator, this can all be done at once.
