Indicate whether the functions an exponential growth or decay

1 answer:

7 0

A function of the form A(t) = Cat where a > 0 and a 1 is an exponential function. The number C gives the initial value of the function (when t = 0) and the number a is the growth (or decay) factor. If a > 1, the function represents growth; If 0 < a < 1, the function represents decay.

A square has sides that measure 6 inches each. What is the ratio of the perimeter of the square to the area of the square?

oksian1 [2.3K]

Answer:

2 : 3

Step-by-step explanation:

Given the square has a side of 6 in , then

perimeter = 4 × 6 = 24 in

area = 6² = 36 in²

Then ratio of perimeter : area

= 24 : 36 ( divide both parts by 12 )

= 2 : 3

$\sqrt{12} - \sqrt{48} =$

$\sqrt{12} - \sqrt{4 \times 12} =$

$\sqrt{4 \times 3} - \sqrt{4 \times 4 \times 3} =$

$\sqrt{ {2}^{2} \times 3 } - \sqrt{ {4}^{2} \times 3 } =$

$2 \sqrt{3} - 4\sqrt{3} =$

$(2 - 4) \sqrt{3} =$

$- 2 \sqrt{3}$

Igoryamba

Answer:

The answer is below

Step-by-step explanation:

a company decided to increase the size of the box for the packaging of their alcohol products. the length of the original packaging box was 40 cm longer than its width and the height 12 cm, volume was at most 4800 cm3. Suppose the length of the new packaging box is still 40cm longer than its width and the height is 12cm, what mathematical statement would represent the volume of the new packaging box?

Solution:

Let the width of the box be x cm.

The length of the box is 40 cm longer than the width, therefore the length of the box = x + 40

The height of the box = 12 cm

The volume of the box can be gotten from the formula:

Volume = length × width × height

Substituting:

Volume = (x + 40) × (x) × 12

Volume = 12x(x + 40)

Therefore the volume of the new box is 12x(x + 40)
