If aₙ = 3(3)ⁿ⁻¹ , what is S₃?<br><br> 12<br><br> 27<br><br> 9<br><br> 39
Allushta [10]

Answer:

S_3=39

Step-by-step explanation:

The nth term of the sequence is

a_n=3(3)^{n-1}

To get the first term, substitute n=1,

a_1=3(3)^{1-1}=3

To get the second term, substitute n=2,

a_2=3(3)^{2-1}=9

To get the third term, substitute n=3,

a_3=3(3)^{3-1}=27

The sum of the first three terms is

S_3=3+9+27=39

We could also use the formula

S_n=\frac{a_1(r^n-1)}{r-1} to get the same result.

Factor 64b-16c to identify the equivalent expressions. *
scoray [572]

Answer:

The factored form of this would be 16(4b - c)

Step-by-step explanation:

In order to find this, look for the greatest common factor of 16 and 64. You can do this by listing out their factors. Once this is done and we identify 16 as the GCF, we can then put that on the outside of the parenthesis and divide all the terms inside by that number.

Can someone help me please
soldier1979 [14.2K]

Step-by-step explanation:

c >= 2

that means any value of c greater or equal to 2 is a valid solution. so, yes, 2 is a solution for this.

c < 2

that means any value of c smaller than 2 is a valid solution. so, no, 2 is not smaller than 2, so it is not a solution.

c < 3

that means any value of c smaller than 3 is a valid solution. so, yes, 2 is smaller than 3, so 2 is a solution.

3 < c

that means any value of c, for that 3 is smaller, is a valid solution. our in other words, any value for c larger than 3 is a valid solution. so, no, 2 is not larger than 3, so it is not a solution.

-8 < c

that means any value of c, for that -8 is smaller, is a valid solution. our in other words, any value for c larger than -8 is a valid solution. so, yes, 2 is larger than -8, so it is a solution.
