Answer:

Surface Area = Surface Area of triangle + SA of rectangle

Surface Area = 3 × (6 × 10) + 2 × ½ × 8 × 10

Surface Area = 3 × 60 + 80

Surface Area = 180 + 80

Surface Area = 260 cm ³

F (x) = - eˣ Baseline (x - 4) What is(are) the critical point(s) of f?

Ber [7]

Answer

given,

$f(x) = \dfrac{-e^x}{x - 4}$

to find the critical point of the given expression

fist differentiating the function

$f'(x) = -\dfrac{(x-4)e^x+ e^x}{(x - 4)^2}$

$f'(x) = \dfrac{-(x-4)e^x- e^x}{(x - 4)^2}$

$f'(x) = \dfrac{-e^x(x-3)}{(x - 4)^2}$

now equating differential equation to zero

$\dfrac{e^x(-x+3)}{(x - 4)^2}=0$

$e^x(-x+3)=0$

now,

-x + 3 = 0 and eˣ ≠ 0

x = 3

the critical number will be equal to x = 3

$y = \dfrac{-e^3}{3 - 4}$

$y =e^3$

x = $\frac{In (2) + In (3)}{In (2) - In (3)}$

Or

x ≈ - 4.41902258
