Answer:

1, 2, 8, 128, 32768

Step-by-step explanation:

recursive \: formula: \\  a _{n} = 2. {( a_{n - 1} )}^{2}  \\  \\ a _{1} = 1...(given) \\  \\ a _{2} = 2. {( a_{2 - 1} )}^{2}   = 2 {(a _{1} )}^{2}  = 2 {(1)}^{2}  \\  \\  a _{2} = 2\\  \\a _{3} = 2. {( a_{3 - 1} )}^{2}   = 2 {(a _{2} )}^{2}  = 2 {(2)}^{2}  \\  \\  a _{3} = 8\\  \\a _{4} = 2. {( a_{4 - 1} )}^{2}   = 2 {(a _{3} )}^{2}  = 2 {(8)}^{2}  \\  \\  a _{4} = 128\\  \\a _{5} = 2. {( a_{5 - 1} )}^{2}   = 2 {(a _{4} )}^{2}  = 2 {(128)}^{2}  \\  \\  a _{5} = 32,768\\  \\

Thus the first five terms are: 1, 2, 8, 128, 32768.

If x = − 6, which number line shows the value of |x|? (5 points)
pashok25 [27]

Answer:  The second description is correct for the absolute value of x

Main details: Horizontal line from 0 to the dot 6 ticks to the left, and 6 written above the line

Step-by-step explanation: breaking it down:

A number line is shown from negative 6 to positive 6 with increments of 1. All the numbers are labeled on the number line. The first part is the same in all of the descriptions

<u>A dot is shown on a point at 6 tick marks to the left of 0. </u> <em>This represents -6 on the number line. </em>

Above the number line, a bracket is shown <u>extending from a point at 6 tick marks to the left of zero to 0.</u><u> </u> This shows the distance between 0 and -6. Important. Absolute value is the distance between two numbers

A horizontal line is shown between the brackets, <em>This is the measuring line 6 units long.</em>

<u> and 6 is written on the line.</u><u> </u> Important. It is a plain number, no negative or positive! Absolute value is just that.

Question 6 of 10
Andreas93 [3]

Answer:

C. 31.64

Step-by-step explanation:

23 = sin(36) × Hypotenuse

Hypotenuse is the baseline between the angles 36° and 54°.

Hypotenuse = 23/sin(36)

x = cos(36) × Hypotenuse

x = cos(36) × 23/sin(36) = cos(36)/sin(36) × 23 =

= 1/tan(36) × 23 = 23/tan(36) = 31.63686382... ≈

≈ 31.64
