A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible

Charra [1.4K]

Answer:

The smallest possible length is 0.83m

Step-by-step explanation:

Given

$Volume = 565L$

Required

The smallest length of the tank

Since the tank is cubical, then the volume is:

$Volume = Length^3$

This gives:

$565L= Length^3$

Express as $m^3$

$\frac{565m^3}{1000} = Length^3$

$0.565m^3 = Length^3$

Take cube roots of both sides

$0.8267m = Length$

Rewrite as:

$Length = 0.8267m$

Approximate

$Length = 0.83m$

What is 0.05 repeating as a fraction ?

grin007 [14]

This is the best I got Require to make 2 equations with the same repeating part and subtract them to eliminate the repeating part.

begin by letting x = 0.5555555................. (1)

To obtain the same repeating part after the decimal point need to multiply by 10

hence 10x = 5.555555........................(2)

It is important to obtain 2 equations in x, where the recurring part after the decimal points are exactly the same.

now subtract (1) from (2) to obtain fraction

(2) - (1) : 9x=5⇒x=59

Answer:

40 ft
t = 1 second

Step-by-step explanation:

A graphing calculator answers these questions easily.

The ball achieves a maximum height of 40 ft, 1 second after it is thrown.

The equation is usefully put into vertex form, as the vertex is the answer to the questions asked.

h(t) = -16(t^2 -2t) +24

h(t) = -16(t^2 -2t +1) +24 +16 . . . . . . complete the square

h(t) = -16(t -1)^2 +40 . . . . . . . . . vertex form

Compare this to the vertex form:

f(x) = a(x -h)^2 +k . . . . . . vertex (h, k); vertical stretch factor 'a'

We see the vertex of our height equation is ...

(h, k) = (1, 40)

The ball reaches a maximum height of 40 feet at t = 1 second after it is thrown.
