Answer:
Add 5 for the first one
The 2nd one is 25 and k or 25 thousand.
Step-by-step explanation:
add 5 for the first one because 5 + 5 = 10
9 + 5 = 14 . and 13 + 5 = 18.
------------------------------------------------------------------
For the 2nd one: 25k means 25 thousand or the Product of 25 and k.

Hey there!!
The area for the volume of a cube -
s³ , s = side
volume = 216
s³ = 216
s = ∛216
s = 6
The required answer is 6
Hope my answer helps!
Answer:
21. y = 75000·0.935^t
22. after 74.6 days
23. y = 27.8112·1.18832^t
24. 18.8% per month
25. 1748
Step-by-step explanation:
22. It is convenient to use the graphing calculator to solve this problem. The number of days is where the exponential curve has the value 500. It is about 74.55 days. (see the first attachment)
__
23. y = 27.8112·1.18832^t (see the second attachment)
__
24. The rate of change is the difference between the base of the exponential and 1, often expressed as a percentage. The time period is the units of t.
(1.18832 -1) × 100% ≈ 18.8% . . . . per month
__
25. Evaluating the function for t=24 gives y ≈ 1748.30425259 ≈ 1748.
