Answer:

  a(n) = 1/2(-8)^(n-1)

Step-by-step explanation:

The general term of a geometric sequence is ...

  a(n) = a(1)×r^(n-1)

where a(1) is the first term, and r is the common ratio.

Here, the first term is a(1) = 1/2. The common ratio is the ratio of any two sequential terms: r = 32/-4 = -8. Then the explicit formula is ...

  a(n) = 1/2(-8)^(n-1)

Let n be an odd integer with exactly 11 positive divisors. Find the number of positive divisors of 8n^3
Tom [10]

Answer: 124

Step-by-step explanation:

As we know, the total number of positive divisors of n is the product of one more than each exponent in the prime factorization of n.

We know this product is equal to 11.

Since 11 is prime, so there can be only one number in this product, so the prime factorization of n must be $n=p^{10}$, where p is a prime number.

We take a cube of the prime factorization of n to give us a prime factorization for n^3

$$n^{3}=\left(p^{10}\right)^{3}=p^{30} .$$

We see that n^{3}\text{ has }$30+1=31$ positive divisors.

Now, 8n^3=2^3\times p^{30}

Totald divisiors = (3+1)(30+1)=4\times31=124

Hence, the number of positive divisors of 8n^3=124

Help plsss I don’t get it
Liula [17]

Answer:

y > 3x - 3

Step-by-step explanation:

First off, to write a linear equation or linear inequality, we use the slope-intercept form: y = mx + b, where m represents the slope of a line, and b represents the y-intercept.

The slope of the line is found using rise/run. The rise, in this case, is 3, and the run is 1. 3/1 is 3. So, we can replace the m in the equation with 3 to get:

y = 3x + b

To find b, simply look for where the line crosses the y-axis (vertical line). In this case, it's -3.

The equation you have now is y = 3x + (-3), which is y = 3x - 3.

You're not done yet. A dotted line like here means a point ON the line is not a solution to the equation, so you have to replace the = with < or >. In this case, the shaded region is everything GREATER THAN -3, meaning you use the > (greater than) symbol.

Your final answer is y > 3x - 3.

Hope this helped!
