The speed of the wind is changing according to the function V(t)=-1/2+30, where t=time in minutes after 6:00 p. m and V(t) = wind speed in miles per hour (mph). Which statement best describes the meaning of the equation V(20)-V(10)=-5? .

D

Step-by-step explanation: In a period of 5 minutes. the wind speed decreases from 20mph to 10mph

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
