An=an−1−4 a1=15 to explicit formula

USPshnik [31]

Answer:

$a_n=3n-12$

Step-by-step explanation:

We are given the recursive formula:

$a_n=a_{n-1}-4, a_1=15$

This is the recursive formula for an arithmetic sequence.

The explicit formula for an arithmetic sequence is given by:

$a_n=a_1 + d({n-1} )$

Where d=3 is the common difference.

We plug in this values to get:

$a_n=15 + 3({n-1} )$

We now expand and simplify to get:

$a_n=15 + 3n-3$

We simplify to obtain:

$a_n= 3n-12$

Please help i need to write out my work to so please tell me how to show it

Anarel [89]

For the first one write 9 divided by 2 gives your your radius an it’s 3.5. the formula is 2 x 3.14 x radius and that gives you 21.98.

the 2nd one is 2 x 3.14 x 9 = 56.52

the 3rd is 2 x 3.14 x 5= 31.4

formula is always 2 x 3.14 (or pie) x radius

to get your radius from your diameter you do your diameter divided by 2

What is the slope of the line that contains the points (-1, 2) and (3, 3)?

iren [92.7K]

Answer:

1/4

Step-by-step explanation:

Slope of a line can be found if given two points by using the formula $\frac{y_2-y_1}{x_2-x_1}$ where $(x_1,y_1) \text{ and } (x_2,y_2)$ are points on the line.
