How to find the nth term

1 answer:

8 0

Find the difference between each term, (e.g 3,5,7,9 —> the difference is 2 so it would be 2n) and then you minus that number from the first term (3-2=1) so therefore the nth term for that sequence would be 2n + 1

At 12 noon in anchorage Alaska Janice noticed that the temperature outside was 12

Alisiya [41]

I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.

This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on

You can follow this sequence to the timing you are looking for.

So then the linear function is y = f(x) = (-1/2)X - 3 y = g(x) = 1/2 * f(x) = (-1/4)x - 3/2 y-intercept is (-1/4)(0) - 3/2 = 0 - 3/2 = -3/2 ... More

A college some completed some courses worth 3 credits and some courses worth 4 credits. The students earned a total of 59 credit

Law Incorporation [45]

The student completed 13 courses with 3 credit hours.

Step-by-step explanation:

Total credit hours = 59 credits hours

Total courses = 18

Let,

3 credit hours courses = x

4 credit hours courses = y

According to statement;

x+y=18 Eqn 1

3x+4y=59 Eqn 2

Multiplying Eqn 1 by 3

$3(x+y=18)\\3x+3y=54\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(3x+4y)-(3x+3y)=59-54\\3x+4y-3x-3y=5\\y=5$

Putting y=5 in Eqn 1

$x+5=18\\x=18-5\\x=13$

The student completed 13 courses with 3 credit hours.
