Answer:
None of the above.
Step-by-step explanation:
All of these are functions. For each input of x, there is only one output of y. Therefore, they are all functions.
Add them together and then you would get the answer
Answer:
I believe 0.75 is the answer. Here is my work:
Step-by-step explanation:
1. 250 divided by 5 = 50 (this is to get 1/5 of 250)
2. 250 divided by 2 (because 1/2 is equivalent to 50% of the overall number) = 125
3. 50 + 125 = 175
4. 250-175 = 75
5. 75 can be converted to 0.75 as a decimal by moving 2 digits over.
Therefore, out of the 250 seventh grade students, 0.75 are in other electives.
Also, I'm in 7th grade so this is my work, I'm sure there are other ways of solving this, too. Please do not add this answer if you don't believe I'm right.
Thanks for your time, and have a nice day! : )
Answer: 0.75
So you have to find the velocity (or first derivative) from the position function of h=-16t^2+48t+6
the velocity is -32t+48 which you then have to set equal to 0 in order to find t
-32t+48=0
-32t=-48
t=1.5
you then take your t value and sub it back into your original position function
-16(1.5)^2+48(1.5)+6 which will give you a maximum height of 42 feet
so the time it takes is 1.5 seconds to reach a maximum height of 42 feet
33 1/3 % is the same as 100/3 % which is equal to 100/300 since per cent means divided by 100.
100/300 simplifies to 1/3 and 1/3 of 90 is simply equal to 30.
