Answer 1

Answer:

x=0.6 =0.6666 eq (1)

multiplying equation (1) with 10

10x -x= 0.6666-0.6666

9x =6

x=6/9

x=2/3

thus , 0.6 =2/3

2.

Here p(x)=3x-2

in order to find the zeros of p (x),we equate p(x)=0

3x-2=0

3x=2

x=2/3

3.

diameter =14

radius =7

surface area of sphere=4πr^2

4π(7)^2

4×3.14 ×49

surface area of sphere is equal to 615.44cm ^2

5.

when a coin is tossed the probability of getting a head is 1/2

6.

1/√7-2=

1/√7-2 ×√7+2 / √7+2

by the formula of

a^2 -b^2 =(a+b) (a-b)

√7+2/7-4

√7+3/3
