Answer:

  • 23 units

Step-by-step explanation:

<em>Perimeter is the sum of side lengths</em>

<u>Let's find the sides first</u>

  • AB = √(-2- 2)² + (-4+1)² = 5
  • BC = (2 - (-1)) = 3
  • CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
  • DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
  • AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32

<u>Perimeter is</u>

  • P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number

Answer:

0.000008 m

Step-by-step explanation:

The diameter of a red blood cell is 8\times 10^{-6}\ m. We need to write the value in the standard notation.

10^{-6} means there are 5 zeros before 8. It can be written as :

8\times 10^{-6}=\dfrac{8}{10^6}\ (\because x^{-a}=\dfrac{1}{x^a})\\\\=\dfrac{8}{1000000}\\\\=0.000008

So, the standard notation is 0.000008 m. Hence, the correct option is (d).

11=3/4 x 3x + 3/4 x 12
11= 9/4x + 9
11-9 = 9/4x
2 = 9/4x
x = 2 x 4/9
