Answer: She will pay $52.68, including taxes
Step-by-step explanation: One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:
can = 3 x 4 = 12
One tennis racket is $43 but it has a discount of 15%:
discount = 0.15 x 43 = 6.45
total racket = 43 - 6.45 = 36.55
Elena will have to pay:
pay = 12 + 36.55 = 48.55
She will also have to pay taxes, which are 8.5% over the price she paid:
pay + tax = 48.55 x 0.085 = 4.13
total to pay = 48.55 + 4.13 = 52.68
Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
Answer:
-infinity
Step-by-step explanation:
plug in numbers for x that is on the right side of the graph and you will see a trend that the larger x is the bigger y is(technically smaller because y would be negative due to the negative sign outside the square root) as x approaches inifity y approaches negative infinity.

Step-by-step explanation:
Answer:
Explicit form: 
Recursive form: 
with 
.
Step-by-step explanation:
The first term is 3 and we are dividing by 3 each time.
Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.
If the first term is 
and 
is the common ratio then the geometric sequence in explicit form is:
The recursive form for a geometric sequence is 
with 
where is the common ratio and is the first term.
So the recursive form for our sequence is with .
