Answer:

i) the length is 10cm

ii) the perimeter is 36 cm

Step-by-step explanation:

i) We know that Area of a rectangle can be found by using the following formula...

A = l x w

(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).

From this we know that

l = A/w

l = 80cm^{2} / 8cm = 10cm

ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...

P = 2(l + w)

P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm

Step-by-step explanation:

Double number line is a diagram used when. quantities have different units.

It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.

some ratios equivalent to 1:3 are;

2:6,3:9,4:12,5:15,6:18,7:21,etc

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.
