Answer: The problem is asking for the surface area of a cylinder.
The formula for surface area of a cylinder is A = 2πrh+2πr²
radius = 1.5
height = 4

A = 2π(1.5)(4)+2π(1.5)²
A ≈ 51.84 in²

A new truck sells for $28,000depreciates (decreases in value) 13% each year. What is the Decay Factor, b?

Answers

not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87

your equation for the prblem is a=p(1-r)^t

when you put $28,000 as A and make 13% into 0.13 and solve your B comes to 0.87. hope this was helpful :)

Eliza Savage received a statement from her bank showing a checking account balance of $324.18 as of January 18. Her own checkbook shows a balance of $487.38 as of January 29. The bank returned all of the cancelled checks but three. The amounts of these three checks are $15.00, $77.49, and $124.28. How much did Eliza deposit in her account between January 18 and January 29?

Answers

Assuming that the three checks that were returned were deposited before Jan 29 and was returned also before Jan 29, the three deposited checks will be added to get 216.77. Next, we subtract 324.18 with 487.38 to get 163.2 which is the difference of Jan 18 and Jan29's balance. Then add 163.2 and 216.77 to get 379.97, the total amount deposited
