Answer:
Step-by-step explanation:
So we have the two functions:
And we want to find g(f(3)).
So, let's find f(3) first:
Multiply:
Subtract:
Therefore, we can substitute -1 for f(3):
Now, find g(-1):
Multiply:
Add:
And we're done!
So:
Answer:
46%
Step-by-step explanation:
Given that:
23/ 50 of Xander's friend prefer to stay at home;
Total number of friend's = 50
Number who prefer to stay home = 23
Hence, percentage who prefer to stay at home :
(23 /50) * 100%
0.46 * 100%
= 46%
Angle A = (arc CD - arc BC) / 2
56 degrees = (arc CD -95) / 2
112 degrees = (arc CD -95)
arc CD = 207
Because, the total number of electrons is equal to the number of protons.
Answer:
x^2 - 8xy + 3y^2 - 2
Step-by-step explanation:
(-8xy + 2x^2 + 3y^2) - unknown = x^2 + 2
- unknown = x^2 + 2 + 8xy - 2x^2 - 3y^2
- unknown = -x^2 + 8xy - 3y^2 + 2
Unknown = x^2 - 8xy + 3y^2 - 2
Check:
(-8xy + 2x^2 + 3y^2) - (x^2 - 8xy + 3y^2 - 2)
= -8xy + 2x^2 + 3y^2 - x^2 + 8xy - 3y^2 + 2
= -8xy + 8xy + 2x^2 - x^2 + 3y^2 - 3y^2 + 2
= x^2 + 2
