Convert 65,000,000 to scientific notation. 6.5 ⋅ 106 6.5 ⋅ 107 6.5 ⋅ 10−6 6.5 ⋅ 10−7

6.5 x 107

Step-by-step explanation:

where y is a number typically between 1 and 10, and z is an integer exponent of 10 that indicates how many places the decimal point must be moved to accomplish this. For example, the number 65000000 would be written 6.5 x 107.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
