6i^4 = 6*1 = 6
6i^3 = 6*(-i) = -6i
-2i^2 = (-2)*(-1) = 2
sqrt(-49) = 7i
So, we have: 6 - 6i + 2 + 7i = 8 + i
The answer is D
Answer:
2/8 which simplifies to 0.111111
Step-by-step explanation:
Answer: f(3) = 14
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given function</u>
f(x) = 4x + 2
<u>Substitute value of the x into the expression</u>
f(3) = 4(3) + 2
<u>Simplify by multiplication</u>
f(3) = 12 + 2
<u>Simplify by addition</u>
f(3) = 
Hope this helps!! :)
Please let me know if you have any questions
A.) There are FOUR significant figures in the number
Let angle be x, then
180 - x + 6 = 2x
3x = 186
x = 62
so the 2 angles are 62 and 118
