Answer:
a, b, d and f
Step-by-step explanation:
To find which equation will have a a mass less than 50 mg after 2 hours, we just need to use the value of x = 2 and then verify if the values of y are less than 50:
a. y = 100*(0.5)^2 = 25 -> apply
b. y = 500*(0.3)^2 = 45 -> apply
c. y = 80*(2)^2 = 320 -> doesn't apply
d. y = 10*(1.2)^2 = 14.4 -> apply
e. y = 30*(1.5)^2 = 67.5 -> doesn't apply
f. y = 80*(0.2)^2 = 3.2 -> apply
g. y = 100*(2)^2 = 400 -> doesn't apply

Step-by-step explanation:
In the first 3 questions, the number codes are:
1 = D
2 = E
3 = A
4 = R
5 = M
6 = W
In the last 3 questions, the number codes are:
1 = T
2 = E
3 = S
4 = R
5 = I
6 = M
Answer:
10 sides, 114, for each interior angle, and 36 for each exterior angle.
Step-by-step explanation:
Since the sum of all exterior angle is 360 multiply by 4 which gets you 1140. Then we know that there are 8 sides to an octagon to find the sum of all the interior angles we can multiply the number of sides minus 2 by 180. Now knowing this we can do this for an octagon which gives us 1080. Since that is close to 1140 we can play around with the numbers and we will eventually go with the number 10 we minus this by 2 and multiply by 180 to get 1140. To find the measurement of 1 interior angle we would divide that number by the sides, so 1140 by 10 to get 114 for our 1 interior measurement. to get the 1 exterior measurement we would divide 360 by the number of sides which gives us 36 since the sum of all exterior measurements equals 360. I hope this helps.
Right format of question:
Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.
Answer:
and ![D' = (-4,8)](https://tex.z-dn.net/?f=D%27%20%3D%20%28-4%2C8%29)
Step-by-step explanation:
Given
![D(x,y) = (-4,1)](https://tex.z-dn.net/?f=D%28x%2Cy%29%20%3D%20%28-4%2C1%29)
Required
Determine a point 7 points from D and in the same x coordinate
Represent this point with D'.
From the requirement of the question, D' has two possible values and these values are:
----> 7 units down and
----> 7 units up
Substitute values for x and y in
and
So, we have:
![D' = (-4,1 - 7)](https://tex.z-dn.net/?f=D%27%20%3D%20%28-4%2C1%20-%207%29)
![D' = (-4,-6)](https://tex.z-dn.net/?f=D%27%20%3D%20%28-4%2C-6%29)
![D' = (-4,1+7)](https://tex.z-dn.net/?f=D%27%20%3D%20%28-4%2C1%2B7%29)
![D' = (-4,8)](https://tex.z-dn.net/?f=D%27%20%3D%20%28-4%2C8%29)
pretty sure the third one
