Answer:

Step-by-step explanation:

The second choice down is the one you want.  I'm not sure why you're confused if you simply have to graph the 2 functions to see on your calculator where they intersect.  Unless you don't know how to access the change of base function in a TI84...

Hit "alpha" then "window" and 5 will open up the option to enter a base on a log.

What is the 7th term of the geometric sequence where a1 = -625 and a2 = 125
kykrilka [37]
Since the sequence is geometric, there is some constant r such that the sequence is recursively given by

a_n=ra_{n-1}

By this definition, you can recursively substitute into the right hand side the definition for a_{n-1},a_{n-2},\ldots to find an explicit formula for the nth term.

a_n=ra_{n-1}=r^2a_{n-2}=r^3a_{n-3}=\cdots=r^{n-1}a_1=-625r^{n-1}

You know the second term, which means you can find r:

a_2=-625r^{2-1}\implies125=-625r\implies r=-\dfrac15

So, the 7th term of the sequence is

a_7=-625\left(-\dfrac15\right)^{7-1}=-\dfrac1{25}

A 6-ounce bag of raisins costs $2.46.An 8-ounce bag of raisins costs $3.20.Which is the better deal?
GenaCL600 [577]
So we need to compare them at the sam ounches


find the least common multiple (the smallest number that they will both multiply into)

first find the factors and group them all together, delete any repeats


6=2*3
8=2*2*2

least common multiple=2*2*2*3=24

so 6 bags=2.46
multiply by 4 to get 24
24 bags=9.84






so 8 bags=3.20
multply by 3
24 bags=9.60


9.84>9.60 so

the 8 ounce bag is less expensive
