I can’t tell what those options are.
The domain is the input values of a function, therefore the x values.
In this case the interval for the domain is
-4< x <= 4
Answer:
99
Step-by-step explanation:
102-2=100
100-1=99
or
102-3=99
Answer:
Step-by-step explanation:
- log₄ (m²) = log₄ (18 - 7m)
18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7
- m² = 18 - 7m
- m² + 7m - 18 = 0
- m² + 2*3.5m + 12.25 = 30.25
- (m + 3.5)² = 5.5²
- m = - 3.5 ± 5.5
You can do part a using The Pythagoras theorem:-
30^2 = x^2 + 24^2
x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324
x = 18
