Answer:

33, 39, 45, 51

Step-by-step explanation:

The general term of an arithmetic sequence is given by the formula ...

an = a1 + d(n-1) . . . where a1 is the first term and d is the common difference

Comparing this formula to the one you are given, you see that ...

a1 = 33, d = 6

This means the first term is 33, and each successive term is 6 more than the previous one. The first 4 terms are ...

33, 39, 45, 51

19. A quadratic equation is shown below.

victus00 [196]

Answer:

$\{\sqrt b, -\sqrt b\}$

Step-by-step explanation:

Given

$a^2 - b = 0$

Required

Determine the solution

Since b is a perfect square, the equation can be expressed as:

$a^2 - (\sqrt b)^2 = 0$

Apply difference of two squares:

$(a - \sqrt b)(a + \sqrt b) = 0$

Split:

$(a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0$

Remove brackets:

$a - \sqrt b= 0 \ or\ a + \sqrt b = 0$

Make a the subject in both equations

$a =\sqrt b \ or\ a =-\sqrt b$

The solution can be represented as:

$\{\sqrt b, -\sqrt b\}$
