Find the Perimeter and Area

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
3 0

Answer:

Area = 20.28 cm^2

Perimeter = 16.28 cm

Step-by-step explanation:

The figure is composed of a half circle and a rectangle,

The circle has a diameter of 7 - 2 - 1 = 4cm and the rectangle is of side 2 cm and 7 cm.

Therefore the area is :

Area = A rectangle + Acircle/2 = 2*7 + pi*r^2/2 = 20.28 cm^2

The perimeter is :

Perimiter = 1 + 2 + 7 + Pcircle/2 = 1 + 2 + 7 + 2*pi*r/2 = 16.28 cm

What is the multiplicative rate of change of the function? The table represents an exponential function.
zhannawk [14.2K]

Answer:

  • <u>The multiplicative rate of change of the function is 0.5</u>

Explanation:

The <em>multiplicative rate of change</em> is the ratio between consecutive entries.

Naming r the multiplicative rate of change, if it is constant you get:

  • r = second entry / first entry = third entry / second entry = fourth entry / third entry.

Here:

  • second entry / first entry = 0.125 / 0.25 = 0.5
  • third entry / second entry = 0.0625 / 0.125 = 0.5
  • fourth entry / third entry = 0.03125 / 0.0625 = 0.5

Thus, the multiplicative rate of change is 0.5. It means that you can obtain each entry as the product of the previous entry times 0.5:

  • 0.25 × 0.5 = 0.125
  • 0.125 × 0.5 = 0.0625
  • 0.0625 × 0.5 = 0.03125

In general, exponential functions have constant multiplicative rate of changes.

Jasmine tossed a coin 20 times. It lands on heads 14 times and tails 6 times. What is the relative frequency of landing on tails
Snowcat [4.5K]

Answer:

The relative frequency of landing on tails is 0.3.

Step-by-step explanation:

The relative frequency of an outcome A is:

The number of trials in which the outcome A happened divided by the total number of trials.

In this problem, we have that:

20 coin tosses, so 20 trials. On 6, it landed on tails.

6/20 = 0.3

This means that the relative frequency of landing on tails is 0.3.
