Answer:

  B.  97.2

Step-by-step explanation:

The sequence of positive terms is ...

  54, 24, 10 2/3, 4 20/27, ...

This sequence has first term 54 and common ratio 24/54 = 4/9. The sum of the infinite series is ...

  S = a1/(1 -r) = 54/(1 -4/9) = 54(9/5)

  S = 97.2

The sum of the positive terms in the infinite series is 97.2.

Which of the following represents the zeros of the function
umka21 [38]
<span>g(x) = x^3 - 9x^2 + 2x + 48 ?

Probe some roots. When you use x = - 2

you will have: (-2)^3 - 9(-2)^2 + 2(-2) + 48 = -8 - 36 - 4 + 48 = 0

So, - 2 is a root

From that you can divide x^3 - 9x^2 + 2x + 48 by x + 2 and you will get

x^2 - 11x + 24

Then you can factor that: (x - 8)(x - 3)

So, the three roots are x = - 2, x = 3 and x = 8, which is the option B.

Answer: option B. x = 8, x = -2 , and x = 3

Can somebody help me with these problems please
const2013 [10]

Answer:

<h3>\huge\sf{Solutions :- }</h3>

<h3>7. Cos Z </h3>

=> Cos theta = Base /Hypotenuse

=> Cos Z = 30/50 => 3/5

★ So, Option <u>B) 3/5 </u> is a correct answer.

_______________________

<h3>8. Cos X </h3>

=> Cos theta = Base/Hypotenuse

=> Cos X = 12/37

★ So, option <u>D)</u><u> </u><u>1</u><u>2</u><u>/</u><u>3</u><u>7</u> is a correct answer.

________________________

<h3>9. Sin Z</h3>

=> Sin theta = Perpendicular/Hypotenuse.

Sin Z = 16/20 => 4/5

★ So, option <u>C)</u><u> </u><u>4</u><u>/</u><u>5</u> is a correct answer

<h3>_____________________</h3>

<h3>10. Sin Z </h3>

=> Sin theta = Perpendicular/Hypotenuse

Sin Z = 48/50 => 24/25

★ So, option <u>A)</u><u>2</u><u>4</u><u>/</u><u>2</u><u>5</u> is correct answer
