Answer:
15+2i
Step-by-step explanation:
Hi there!
We are given the following expression:
(7-4i) + (8+6i)
And we want to write it as a complex number in standard form
Standard form is <u>a+bi</u>, where a is the real part of the number and bi is the imaginary part of the number.
We can open up the parentheses on the expression
7-4i+8+6i
Now combine the like terms (add 8 and 7 together, then add -4i and 6i together)
<u>15+2i </u>
The complex number is now in standard form
Hope this helps!

Answer:
- V(t) = 25(1.07^t)
- V(t) = 40(1.05^t)
Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
<u>Coin A</u>
P = 25, r = .07
V(t) = 25(1.07^t)
<u>Coin B</u>
P = 40, r = 0.05
V(t) = 40(1.05^t)
215 because you would add and subtract the numbers as you go them you come out with your answer
