What is the sum of the geometric sequence 4, 16, 64, ƒ if there are 8 terms?
pogonyaev
In a Geometric Sequence,<span> each term is found by </span>multiplying<span> the previous term by a </span>constant<span>. For this case, the constant is 4. To find the sum of the geometric sequence with 8 terms, we use the formula as follows:

</span>∑(ar^k) = a ( 1-r^n) / (1-r)
<span>
where a is the first term, r is the constant, n is the number of terms

 </span>∑(ar^k) = 4 ( 1-4^8) / (1-4)
∑(ar^k) = 87380

If tanA+cotA=2 then find the value of cosA​
aniked [119]

Answer:

cos A=

\frac{1}{ \sqrt{2} }

Step-by-step explanation:

We know,

cotA=

\frac{1}{ \tan(a) }

Substituting the value of cot A in the given equation, we get

\tan( a)  +  \frac{1}{ \tan(a) }  = 2

\frac{{ \tan }^{2} a + 1}{  \:  \tan(a)  }  = 2

{ \tan }^{2 \: } a \:  + 1 = 2 tan \: a

{ \tan }^{2} a - 2 \tan \: a + 1 = 0

( \tan \: a - 1) {}^{2 }  = 0

\tan \: a - 1 =  \sqrt{0}

\tan \: a = 1

\tan \: a \:  =  \tan \: 45

a = 45

\cos \: a =  \cos \: 45

\cos \: a =   \frac{1}{ \sqrt{2} }

I think that the answer should be B.

B because the owner should have found 25% of 46 by multiplying 0.25 x 46.
