Answer:
Let a be the first term.
The sum is a1−r=33.25.
The second term is ar=7.98, so a=7.98/r.
Putting these together, 7.98/r(1−r)=33.25 or r(1−r)=0.24=0.6×0.4.
If the answer doesn't jump out at you from there, you could solve for r with the quadratic formula.

Answer:</h3>
The mean age decreased.
<h3>
Step-by-step explanation:</h3>
I find it convenient to look at the additions with respect to the current mean age.
The current total age is 14×34. We have added members with ages (34 -10) and (34 +2), so the new total age is ...
... (34×14) + (34 -10) + (34 +2) = (16×34) - 8
Dividing this total by 16 will give the new mean age. (We already know it is less than 34.)
... ((16×34) -8)/16 = 34 - 1/2 = 33 1/2 . . . new mean age; a decrease
Answer: The correct option is ΔABC ≅ ΔFED by SAS
Step-by-step explanation:
Looking at the given diagram,
Side AC = Side DF = 3.2
Side AB = Side FE = 4 units
Angle A = angle F = 72 degrees
Since two sides and one angle are equal, then triangle FED = triangle ABC by SAS(side angle side)
This makes the ratios possible
AB/FE = AC/DF
The HL given means hypotenuse leg. It will not hold because the triangles are not right angle triangles.

So you can see there are 12 zeros before you hit the first non-zero, which is 2.
