Which of the following equations represents a line that is perpendicular to y=3x+11 and intercepts the line at the point, (-2, 5

yaroslaw [1]

If the line is perpendicular the slope is the reciprocal so it would be
Y=-1/3x
Then if the line has to go through the point (-2,5) the y-intercept must be 5 making the answer
Y=-1/3x+5

Write a recursive rule for the sequence. Assume it starts with the 1st term. 10, 14, 18, 21...

Papessa [141]

Option D is correct. The correct option for the recursive formula is $f(0) =6;f(n)=f(n - 1)+4$

Given the sequence 10, 14, 18...

The first term is 10, hence

a1 = 10

The previous terms will be $a_{n-1}$

From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

$a_n = a_{n-1} + 4$

Get the term before the first term $a_0$

If n = 1

$a_1 = a_{1-1} + 4\\a_1 = a_{0} + 4\\a_0=a_1-4\\a_0=10-4\\a_0=6$

Hence the correct option for the recursive formula is $f(0) =6;f(n)=f(n - 1)+4$

serious [3.7K]

Answer:

$1200.

Step-by-step explanation:

We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.

First of all we will find the number of subscribers for this month.

$\text{Total number of subscribers this month}=100+30-10$

$\text{Total number of subscribers this month}=130-10=120$

Now let us multiply number of total subscribers of this month by 10 to find the amount Kiersten will earn by her online business.

$\text{Kiersten's earnings this month from online business}=120*10$

$\text{Kiersten's earnings this month from online business}=1200$

Therefore, Kiersten will earn $1200 this month by her online business.
