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! Will give brainly, 50 points!! I'm stuck with this question and I don't get it!!

His answer was (x- +2) (x^2-9)

a) His mistake was he has x^2 in one of the parenthesis, to be fully factored you cannot have an exponent as part of the answer.

b) x^3 - 9x + 2x^2 -18

Reorder the terms:

x^3 +2x^2 -9x -18

Group the first two terms and the last two terms

(x^3 + 2x^2) -9x-18

Factor out the greatest common factor from each group:

x^2(x+2) - 9(x+2)

Factor the polynomial by factoring out the common factor once x+2:

(x+2) (x^2-9)

Rewrite 9 as 3^2:

(x+2) (x^2-3^2)

Factor one last time:

(x+2) (x+3) (x-3)

zubka84 [21]

Answer:

3/8 and 3/5

Step-by-step explanation:

Given that a family has three children. Using b to stand for a boy and g for girl give the following we can write sample space for a family having three children as

(bbb, bbg, bgg, bgb, gbb, gbg, ggb, ggg)

E - exactly two boys

Sample space count = 8

Exactly two boys count = 3

a) p(E) = $\frac{3}{8}$

b) odds for E is probability/1-probability

= $\frac{3}{5}$
