A microwaveable cup-of-soup package needs to be constructed in the shape of cylinder to hold 350 cubic

const2013 [10]

Answer:

x = r = 3,12 cm

h = 11,45 cm

C(min) = 10,09 $

Step-by-step explanation:

Let x be radius of base and h height of cylinder

Let A₁ be Cylinder area of base + lateral area

A₁ = π*x² + 2*π*x*h Now V = 350 cm³ 350 = π*x²*h

h = 350/ π*x²

Then

A₁ = π*x² + 700/x

A₂ area of the top

A₂ = π*x²

Now we write the expression of cost as fuction of x

C(x) = 0,03 * ( π*x² + 700/x) + 0,08*π*x²

C(x) = 0,03* π*x² + 21/x + 0,08*π*x²

C(x) = 0,11* π*x² + 21/x

Taking derivatives on both sides of the equation

C´(x) = 2*0,11*π*x - 21 / x²

C´(x) = 0 0,22*π*x - 21 / x² = 0

0,22*π*x³ - 21 = 0 0.6908* x³ - 21 = 0

X³ = 21/0,6908 X³ = 30,40

x = 3,12 cm

And

h = 350/π*x² h = 350 / 30,57

h = 11,45 cm

C(min) = 0,11* π*(3,12)² + 21/3,12

C(min) = 3,36 + 6,73

If x=5^a, find the value of 5x

Harrizon [31]

Answer:

The given expression is written as $5^{1+a}$

Step-by-step explanation:

Given as :

The expression is written as x = $5^{a}$

Now foe 5 x , the expression is written as

$5^{1}$ × $5^{a}$

Now <u>from base indices method </u>

here base is same so, power should be added

∴ $5^{1+a}$

Hence The given expression is written as $5^{1+a}$ , Answer
