Answer: A 24 cm piece of string is cut into two pieces , one piece is used to form a circle and the other piece is used to form a square.

How should this string be cut so that the sum of the areas is a minimum .

Let x = the circumference of the circle

then

(24-x) = the perimeter of the square

Find the area of the circle

find r

2*pi*r = x

r =

Find the area of the circle

A =

A = sq/cm, the area of the circle

Find the area of the square

A = sq/cm the area of the square

The total area

At = +

Graph this equation, find the min

Min occurs when x=10.6 cm

cut string 10.6 cm from one end

Step-by-step explanation: Hope I help out alot (-: :-)

Simply the function f(x)=7(3Square root 54^x)

Pie

Answer:

54 = 2 × 3 × 3 × 3 = 2 × 3³

$f(x) = 7(\sqrt[3]{54})^x$

$f(x) = 7(\sqrt[3]{3^3 \times 2})^x$

$f(x) = 7(3\sqrt[3]{2})^x$

Initial value: x = 0

$f(0) = 7(3\sqrt[3]{2})^0$

$f(0) = 7(1)$

$f(0) = 7$

The initial value is 7.

The domain is all real numbers.

The range is all real numbers greater than zero.

Convert 2 1/2 an improper fraction

soldier1979 [14.2K]

Answer:

2 1/2 = 5/2

Step-by-step explanation:

There is a trick you can do when converting mixed numbers into improper fractions

Multiply the whole number and denominator, in this case you'll do 2 * 2 which equals 4

Finally, add the numberator to your product. For this you'll do 4 + 1 which equals 5

When done, keep the denominator and keep your sum as the numerator. 5/2!
