Answer:
answer is 90 for first term
Step-by-step explanation:
Let the terms be
First term x
We will use the formula s∞=x/1−r to find the sum of an infinite geometric series, where −1<r<1.
We know the sum and the common ratio, so we'll be solving for x where r =4/5
s∞=x/1−r
450=x/1−4/5
450=x/1/5
450=5x
x=90
this is the first term x1 = 90
we know that common ratio is 4/5, so multiplying the first term by factor 4/5 to get the second term
90 x 4/5= 72 second term
If they are in the same line yes. If they aren't then its considered non-collinear.
The original price was $70.2. (If it’s not supposed to have cents then it’s just $70).
This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
