Answer:
The base (b) has to be positive and different of 1. The logarithm is the inverse of exponential, so:
logb(a) = x ⇒ a = bˣ
So, for b = 0 ⇒ 0ˣ = a
And there is impossible, "a" only could be 0.
For b = 1 ⇒ 1ˣ = a
And the same thing would happen, the logarithming would be to be 1, and the function will be extremally restricted.
For b<0, then the expression a = bˣ will be also restricted, and will not represent all values of a.
So, 0<b<1 and b >1.
108÷6 = 18 and 84÷6=14 last one is 184÷8=23
Answer:
a
Step-by-step explanation:
The inverse would be
f^-1(x) = x/5 - 2/5
Answer:
(a) 105°
(b) 75°
(c) 105°
Step-by-step explanation:
According to the options, we have,
(a) The car is travelling west on the 4th street and turns towards south on King Avenue.
So the angle (a) will be the angle made by the car's turning.
As, ∠(a) + 75° = 180°
i.e. ∠(a) = 180° - 75°
i.e. ∠(a) = 105°
(b) The car is travelling southwest on the King Avenue and turns right onto 3rd street.
So the angle (b) will be the angle made by the car's turning.
As, 3rd and 4th street are parallel. So, the corresponding angles have equal measures.
Thus, ∠(b) = 75°
(c) The car is travelling northeast on the King Avenue and turns right onto 4th street.
So the angle (c) will be the angle made by the car's turning.
As, ∠(c) + 75° = 180°
i.e. ∠(c) = 180° - 75°
i.e. ∠(c) = 105°
