Answer: 38 meter per second
Step-by-step explanation:
Given: The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.
where -38 is the rate of change of function .
Since speed is the rate of change of position with respect to time , thus
Speed =-38 meter per second which shows decrease in distance with respect to time.
At t=0 second, d=220 meters
At t=1 second , 
meters
Distance traveled in 1 second = 220-182=38
Now, Rachel's speed=
Rachel's speed=
=38 meter per second
Well, I know that there are 128 ounces in 1 gallon, so
128/2 = 64
There are 64 ounces in 1/2 a gallon. :)
We know that there are 21 buttons total. x is the number of small buttons and y is the number of large buttons.
Therefore, our first equation should be x+y = 21.
We know the small buttons sell for 3 dollars, meaning 3x represents how much is made from the small buttons. The larger buttons sell for 4 dollars, meaning 4y is how much is made from the large buttons.
We also know that the total of the buttons sold is 68 dollars. Therefore 3x + 4y = 68 is our second equation.
From this information, the answer is the first set.
Divide 6 3/8 lb by 3/8 lb to obtain the number of 3/8 lb bags:
6 3/8 6.375 lb
------- = ---------------------- = 17 bags (answer)
