First, determine the domain:  x ≥ 0  <em>(because you can't square root a negative)</em>

Next, square both sides of the equation and solve for "x".

(√x)² < (5)²

+/- x < 25

+x < 25        -x < 25

 x< 25           x > -25  ⇒ <em>Remember the domain is x ≥ 0</em>

x < 25   and  x ≥ 0 ⇒ 0 ≤ x

Answer: 0 ≤ x < 25    <em>interval notation [0, 25)</em>

Answer:

T_{15} = 9565938

Step-by-step explanation:

Given

Sequence: 2, 6, 18, 54, 162,

Required

Determine the 15th term

The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)

r = \frac{T_2}{T_1}

r = \frac{6}{2}

r = 3

The 15th term is calculated as thus:

T_n = ar^{n-1}

Where

a = 2 and n = 15

T_n = 2 * 3^{15-1}

T_n = 2 * 3^{14}

T_{15} = 2 * 4782969

T_{15} = 9565938

<em>The 15th term is 9,565,938</em>
