Answer:
Step-by-step explanation:
Start by making a common denominator. In this case, it would be 12.
Multiply -1/3 by 4 to get -4/12
Multiply -9/4 by 3 to get -27/12
Then subtract
- - (-
) =23/12
You can also visualize this on a number line. Once you've made the denominator the same, start at -4/12 and move 27 units to the left to land on 23/12.
If one of our zeros is 4, then the factor is x-4. If the second zero is 5i, then the conjugate root theorem says there HAS to be a root that is -5i. So our 3 factors are (x-4)(x+5i)(x-5i). We will FOIL out these factors to get the polynomial. Let's start with the ones that contain the imaginary numbers. Doing that mutliplication we get x^2-25i^2. i^2 is equal to -1, so what that expression simplifies down to is 
. Now we will multiply in that last factor of (x-4): 
. FOILing out we have 
. There you go!
The series is a geometric series and the sum of the first 8 terms of the series 48, 60, 75 is 952.32
<h3>How to determine the sum of the first 8 terms?</h3>The series is given as:
48, 60, 75
The above series is a geometric series with the following parameters:
First term, a = 48
Common ratio, r = 1.25
The sum of n terms is:
So, we have:
Evaluate
Hence, the sum of the first 8 terms of the series is 952.32
