Answer:
1. 20
2. 23
3. 6
Step-by-step explanation:
We have that:
f(x) = 2x
g(x) = x² + 1
f(g(x)) is the composite function of f and g. So
f(g(x)) = f(x²-1) = 2(x²+1) = 2x² + 2
1. f(g(3))
f(g(x)) = 2x² - 2 = 2(3)² + 2 = 18 + 2 = 20
2. f(3)+g(4)
f(3) = 2(3) = 6
g(4) = 4² + 1 = 17
f(3) + g(4) = 6 + 17 = 23
3. f(5) - 2g(1)
f(5) = 2(5) = 10
g(1) = (1)² + 1 = 2
f(5) - 2g(1) = 10 - 2*2 = 10 - 4 = 6
Answer:
A =4πr2
Step-by-step explanation:
22%. Make it a percent and it'll be 22%.
21/25 is already a fraction and if you wanted it to be simplified, its already simplified to be 21/25.
P = The kitchen is clean → TRUE
Q = The bedroom is clean → FALSE
1) If P is true, then Q is true. → False statement
2) Statement Q is true if and only if P is true. → False statement
3) Both p and q are true. → False statement
4) Statement P or Q is true. → True statement ⇒ Statement P is true.
The answer is: The statement "Statement P or Q is true" is true.
There you go! I really hope this helped, if there's anything just let me know! :)
