compute each sum below. if applicable, write your answer as a fraction.
5+5(-2)+5+(-2)^2++5(-2)^7=
9
∑ (1/4i)=
i=1

First equation is -425

Second equation is 11.25

Step-by-step explanation:

First equation we can write as

computing

When i=0 ->

When i=1 ->

...

When i=7 ->

then replacing each term we have

For the second equation we'll have 9 terms, solving in a similar fashion

When i=1 ->

When i=2 ->

When i=3 ->

...

When i=9 ->

So we have 0.25 + 0.50 + 0.75 + 1.00 + 1.25 + 1.50+ 1.75 +2.00 +2.25

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the monthly balance will be $75,000
