Alex73 [517]3 years ago
8 0

Answer:

See below.

Step-by-step explanation:

We know that

                              tanA + tan B

tan (A + B)     =     ---------------------                       

                               1 - tanAtanB

Substituting for A + B

tan (A + B) = tan pi/4 = 1.

            tanA + tan B

So        ------------------   =    1

             1 - tanAtanB

Therefore   tanA + tan B =   1 - tanAtanB.

The value of the 4th term is 80. the sequence is being doubled each step what is the 7th term?
leva [86]
This is a geometric sequence with common ratio (r) = 2.
an = ar^(n - 1)
a4 = a(2)^(4 - 1) = a(2)^3 = 8a
8a = 80
a = 80/8 = 10

7th term (a7) = 10(2)^(7 - 1) = 10(2^6) = 10(64) = 640
