To find f(-2), substitute (-2) into x of the function f(x) = 4x^2-2
We get, f(-2) = 4(-2)^2 - 2
 = (4*4)-2 = 16-2 = 14
Therefore, f(-2)=14.
        
             
        
        
        
Answer:
m∠Z = 166°
Step-by-step explanation:
Since we know that the angles add up to 720°, we can set up an equation to solve for the variable x:
12x + 14x - 6 + 108 + 108 + 108 + 90 = 720
26x + 408 = 720
26x = 312
x = 12
Now we substitute the number in for x to solve ∠Z:
m∠Z = 14(12) - 2 = 166
m∠Z = 166°

Answer:
255
Step-by-step explanation:
The n th term of a geometric series is
 = a
 = a
where a is the first term and r the common ratio
1 ← is the n th term
 ← is the n th term
with a = 1 and r = 2
The sum to n terms of a geometric series is
 =
 =  , thus
, thus
 =
 = 
     =  - 1 = 256 - 1 = 255
 - 1 = 256 - 1 = 255
