Answer:  \bold{a)\quad 51, 54, 57\qquad a_n=a_{n-1}+3}

               \bold{b)\quad 250, 625, 1562.5\qquad a_n=(2.5)a_{n-1}}

<u>Step-by-step explanation:</u>

a) This is an arithmetic sequence where 3 is added to the previous term.

48 + 3 = 51

              51 + 3 = 54

                            54 + 3 = 57

The recursive formula for this sequence is:  a_n = a_{n-1}+3

*****************************************************************************************

b) This is a geometric sequence where 2.5 is multiplied to the previous term.

100(2.5) = 250

                250 (2.5) = 625

                                    625(2.5) = 1562.5

The recursive formula for this sequence is: a_n=(2.5)a_{n-1}

larisa [96]

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2.  (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± \sqrt{b^{2}-4ac } / 2a

Substitute in:

-6 ±\sqrt{7^{2} -4(2)(6)} / 2(2)

-6±\sqrt{49 - 48} / 4

Both forms:

-6 + \sqrt{1} / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75

An angle measures 32° more than the measure of its complementary angle. What is the measure of each angle?
Leviafan [203]

Answer:

29° ; 61°

Step-by-step explanation:

Let one angle  = x°

Other angle = (x + 32)°

x + x + 32 = 90   {given they are complementary}

2x + 32 = 90

2x = 90 -32

2x = 58

x = 58/2

x = 29

One angle  = 29°

Other angle = 29 + 32 = 61°
