Step-by-step explanation:

A scientific notation is a way to represent very large values into the decimal form.

Steps to write in scientific notation:

Move the decimal to left before first digit of the given number.

Find the number of times decimal is moved to left.

Put that number in the exponent of e.

So, matching:

a) 864,000,000,000 8.64E11

b) 8,640,000,000 8.64E9

c) 86,400,000,000,000 8.64E13

Each side of a rhombus is 20 cm long and one of its diagonals is 24 cm in length, find the area of this rhombus?

vodomira [7]

Answer:

AB = 20 CM

OA = 1

__ × 24 cm

= 12 cm

AOB = 90 °

OB² == AB² - OA ²

$( {20}^{2} ) - ( {12}^{2} ) \\ = 400 - 144 \\ = 256 \\$

$ob \: = \sqrt{256} = 16 \\ bd \: = 2 \times ob \\ = 2 \times 16 \\ = 32cm \: \\$

AREA OF ABCD IS

$\frac{1}{2 } \times ac \times bd \\ = \frac{1}{2} \times 24 \times 32 \\ 384cm$

$hope \: its \: helpful \: \: to \: you \:$

Is the power produced directly proportional to the wind speed, give reasons for your answer?

yuradex [85]

Answer:

Is the power produced directly proportional to the wind speed.

No.

A proportional function can be described as y = a * x

So (0, 0) is on the graph, not (3, 0).

0 / 3 = 0

3800/6 = 633.33

7600/9 = 844.44

13600/12 = 1133.33

The quotient y/x should be always the same.
