Answer:

BC ≈ 8.6

Step-by-step explanation:

Using Pythagoras' identity in the right triangle , that is

BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )

BC = $\sqrt{74.45}$ ≈ 8.6 ( to 1 dec. place )

May someone help me out with this question please

You would have 60 different types of pens with this brand. You need to multiply 12 and 5 (because you have 12 different colors for every type of tip, so you have 5 groups of 12).

What is a formula for the nth term of a given sequence

IceJOKER [234]

Answer:

$a_n=-12-4(n-1)$

Step-by-step explanation:

The given sequence is

-12,-16,-20...

The first term of this sequence is $a_1=-12$ .

The common difference is

$d=-16--12$

$d=-16+12=-4$

The nth term of this arithmetic sequence is;

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

We substitute the values for the first term and the common difference to obtain;

$a_n=-12-4(n-1)$
