Desperate ->and explain! : )
"the average translational kinetic energy of a gas molecule of mass m is given by (mv^2)/2 = 1.5at, where v is the molecule's average speed, a is the boltzmann constant, and t is the absolute temperature (k). assume that there is one hydrogen atom per cm^3 in outer space, where the temperature is 3.5k. determine the particle's average speed."

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

83-45=38

38 was the other number

hope your goes well, here's a turkey
