Answers

Answer:

75 ft

Step-by-step explanation:

Here we are given a right angled triangle with a known angle of 20°, length of the hypotenuse to be 80 and we are to find the length of the base x.

For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.

cos \alpha =(base)/(hypotenuse)

So putting in the given values to get:

cos 20=(x)/(80) \n\nx= cos 20*80\n\nx=75.17

Therefore, the value of x is the closest to 75 ft.

A cylindrical can without a top is made to contain 25 3 cm of liquid. What are the dimensions of the can that will minimize the cost to make the can if the metal for the sides will cost $1.25 per 2 cm and the metal for the bottom will cost $2.00 per 2 cm ?

Answers

Answer:

Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.

Step-by-step explanation:

Given that, the volume of cylindrical can with out top is 25 cm³.

Consider the height of the can be h and radius be r.

The volume of the can is V= \pi r^2h

According to the problem,

\pi r^2 h=25

\Rightarrow h=(25)/(\pi r^2)

The surface area of the base of the can is = \pi r^2

The metal for the bottom will cost $2.00 per cm²

The metal cost for the base is =$(2.00× \pi r^2)

The lateral surface area of the can is = 2\pi rh

The metal for the side will cost $1.25 per cm²

The metal cost for the base is =$(1.25× 2\pi rh)

                                                 =\$2.5 \pi r h

Total cost of metal is C= 2.00 \pi r^2+2.5 \pi r h

Putting h=(25)/(\pi r^2)

\therefore C=2\pi r^2+2.5 \pi r * (25)/(\pi r^2)

\Rightarrow C=2\pi r^2+ (62.5)/( r)

Differentiating with respect to r

C'=4\pi r- (62.5)/( r^2)

Again differentiating with respect to r

C''=4\pi + (125)/( r^3)

To find the minimize cost, we set C'=0

4\pi r- (62.5)/( r^2)=0

\Rightarrow 4\pi r=(62.5)/( r^2)

\Rightarrow  r^3=(62.5)/( 4\pi)

⇒r=1.71

Now,

\left C''\right|_(x=1.71)=4\pi +(125)/(1.71^3)>0

When r=1.71 cm, the metal cost will be minimum.

Therefore,

h=(25)/(\pi* 1.71^2)

⇒h=2.72 cm

Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
