Recursive & Explicit Definitions

natali 33 [55]

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 $n = 15$

$T_n = 2 * 3^{15-1}$

$T_n = 2 * 3^{14}$

$T_{15} = 2 * 4782969$

$T_{15} = 9565938$

A skateboard ramp is 17 inches high and rising an angle of 25° how long is the base of the ramp?

Katen [24]

Answer:

36.46 inches

Step-by-step explanation:

The tangent of the angle is the ratio of the height to the base length:

Tan = Opposite/Adjacent

tan(25°) = (17 in)/(base)

base = (17 in)/tan(25°) ≈ 36.46 in

The base of the ramp is about 36.46 inches long.
