the answer for the problem in the pic is A i think
Answer:
Final amount = $5357.52
Step-by-step explanation:
Formula to be used,
Final amount = 
Here, n = number of compounding in a year
t = Duration of investment
Now we substitute the given values in the question.
Final amount = 
= 
= 1210(4.4277)
= $5357.52
Answer:
Step-by-step explanation:
Combine real terms and combine complex terms
1) 3 + 2i + 2 - 5i = 3 +2 + 2i - 5i
= 5 + (2-5)i
= 5 + (-3)i
= 5 - 3i
3) 2 - (1 - 2i) + (4 -5i ) - (1 - 3i) = 2 -1 + 2i + 4 - 5i - 1 + 3i
{- is distributed to (1 - 2i) & - is distributed to (1- 3i)}
= 2 - 1 + 4 + 1 + 2i - 5i + 3i
= 6 +0i = 6
5) 4 - 3i + 4 + 3i = 4 +4 -3i + 3i
= 8
7) (3 - 2i)² + (3 +2i) = 3² - 2*3*2i + (2i)² + 3 + 2i {(a - b)² = a² - 2ab +b²}
= 9 -12i + 4i² + 3 + 2i
= 9 - 12i + 4*(-1) + 3 + 2i {i² = -1}
= 9 +3 - 4 - 12i +2i
= 8 - 10i

Answer:
-1/7
Step-by-step explanation:
To find the x-intercept, set y=0 and solve for x.
0 = 7/4x +1/4
Multiply by 4/7
0 = x + 1/7
Subtract 1/7
-1/7 = x
The x-intercept is -1/7.
