Answer:
D
Step-by-step explanation:
Exponential equation takes the form 
where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as 
, so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
Answer:
x = 26
Step-by-step explanation:
The sum of the angles around point O = 360°, thus
x + 3x + 256 = 360 , that is
4x + 256 = 360 ( subtract 256 from both sides )
4x = 104 ( divide both sides by 4 )
x = 26
