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°
Try 4 times $28 witch is $112 hope it helps and if I’m wrong sorry
Answer:
255
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
1
← is the n th term
with a = 1 and r = 2
The sum to n terms of a geometric series is
=
, thus
= 
=
- 1 = 256 - 1 = 255
