Answer:
Step-by-step explanation:
a) 3 x 5
b) 15 Celcius
1. There is no "h" in f(x) = log(x). The question is nonsense.
2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.
3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.
4. Same deal. Choose B, though D is also correct.
5. C is the proper choice. (See discussion of the log function, above.)
Answer:
x = 45, y = 90
x = 60, y = 75
x = 25, y = 110
Step-by-step explanation:
Answer:
$115.20
Step-by-step explanation:
Hi! We need to find 1% of 96 to multiply by 20.
96 / 100 = .96
Now we multiply by 20.
20 x .96 = 19.2.
Now, we add 19.2 to what she earned in the first place (96).
19.2 + 96 = 115.20
Hope this helps!
