Which sequence could be described by the explicit definition: t_n=2^n+1t n = 2 n + 1

yuradex [85]

Answer:

2. 27

3. Option C. 3, 5, 9, 17, 33, ...

Step-by-step explanation:

2. The sequence is defined by the explicit function $t_{n} = 2^{n} - n$

Therefore, the 5th term i.e. $t_{5}$ of the sequence.

$t_{5} = 2^{5} - 5 = 32 - 5 = 27$ (Answer)

3. The explicit definition is $t_{n} = 2^{n} + 1$

Hence, $t_{1} = 2^{1} + 1 = 3$

$t_{2} = 2^{2} + 1 = 5$

$t_{3} = 2^{3} + 1 = 9$

$t_{4} = 2^{4} + 1 = 17$

Therefore, the option C is the right sequence. (Answer)

1-sina/cosa=cosa/2-sina/2÷cosa/2+sina/2

Serhud [2]

Step-by-step explanation:

Let's take the RHS,

we've,

Let's Rationalise the Denominator.

we get,

The numerator is in form of (a-b)^2 and the denominator is in form of a^2-b^2. Now,

By formula,

Here I substituted Cosa in place of (Cosa/2)^2 - (sina/2)^2 because it's the formula of cosa in sub multiple angle form.

<h3>In the numerator, </h3>

(sina/2)^2 + (Cosa/2)^2 =1.........( by formula)

so we have,

<h3 /><h3 /><h3>1 - sina {because 2sina/2.cosa/2=sina)</h3><h3>Cosa</h3>

LHS proved.

Thank You.
