Answer:
A
Explanation:
For functions to be inverse, it must be true that f( g(x) ) = x and g( f(x) ) = x.
But for F( G(x) ), we have √( G(x) - 3 ) + 8
= √( (x+8)² - 3 - 3 ) + 8
= √( (x+8)² - 6 ) + 8
This -6 part should be cancelled out for functions to work out but we cannot do that, therefore F(x) and G(x) are not inverse.
1.
List the scores:
(2) 60
(1) 65
(5) 75
(1) 95
(1) 100
Find the chart with those quantities: Chart A
2. Find the mean:
75 + 60 + 75 + 100 + 75 + 75 + 75 + 95 + 60 + 65 = 755
755/10 = 75.5
Subtract the mean from Ashley’s score:
60 – 75.5 = -15.5
The answer is D.
I the answer To You Problem Is C
Answer:
8 kilos of it is gold, since 2/5 in decimal form is 0.40
12 kilos of it is copper.
Step-by-step explanation:
Multiply 20 times 0.40, you get 8, so 8 kilos of it is gold, while 12 kilos is copper.
