Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
Answer:
Step-by-step explanation:
GIVEN: A hotel charges a annual fee plus an additional for each night you stay there.
TO FIND: average cost per night if you stay at the hotel for nights.
SOLUTION:
Annual fee charged by hotel
amount charged each night we stay there
Total number of nights we stay
Total amount paid for nights
Total amount paid
average cost per night
putting values,
average cost per night
Hence average cost per night if we stay at hotel for days is

Use the surface area formula for a cylinder! 2πrh+2πr2
Plug in what you know! (If the diameter is 8, then that means the radius is 4.)
r = 4
h = 12
2π(4)(12) + 2π(4)(12) = 402.12
I hope this helps! :)
To get the effective interest rate (EIR) of the loan, determine first whether we will use a simple interest method or a discounted method. In this case, we will use a discounted method because the loan is a discounted one. In a discounted method, interest is deducted from the loan principal. So the formula will look like this:
EIR = Interest ÷ (Principal - Interest)
Before proceeding any further, solve first for interest. (assuming a 360-day year)
Interest = Principal × rate × interest
= $2950 × (100/360) × (0.085)
= $69.65
Thus, EIR can be computed as follows:
EIR = ($69.65 ÷ ($2950 - $69.65)) × 360
≈ 8.7%
Notice that the EIR was multiplied by 360 to return it to an annual rate.
