fenix001 [56]

Answer:

$a_2 = 8$

$a_3 = 18$

$a_4 = 38$

Step-by-step explanation:

We are given the following recursive formula:

$a_n = 2(a_{n-1}+1)$

And consider $a_1 = 3$

$a_2 = 2(a_1 + 1) = 2(3 + 1) = 8$

$a_3 = 2(a_2 + 1) = 2(8 + 1) = 18$

$a_4 = 2(a_3 + 1) = 2(18 + 1) = 38$

19 is 50% of what number

RSB [31]

If 19 is half (50%) of something, find that number you would just have to multiply 19 by 2.

This means that 19 is 50% of 38.

A line passes through the points (0,3), (4,1) and (6,0). Which function best represents the relationship between the two points?

Veronika [31]

Answer:

y = - $\frac{1}{2}$ x + 3

Step-by-step explanation:

y = mx + b

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ and "b" is y-intercept with coordinates (0, b)

(0, 3) ⇒ b = 3

(4, 1), (6, 0)

m = $\frac{0-1}{6-4}$ = - $\frac{1}{2}$

y = -  $\frac{1}{2}$  x + 3
