Well, to understand what "n" is, we have to understand the relation between 18 and 27.
If we divide by 9, we'll notice that 18/27 simplifies to 2/3.
So, let's apply this to 10/n
10 over n must be the same ratio of 2/3.
10/2 is 5.
5*3 = 15.
n = 15.
Alternatively, cross multiply and solve.
10/n = 18/27
n will multiply with 18, 10 with 27.
18n = 270
/18     /18
n = 15

N = 10*27 / 87 =  270/18 = 15

Find the 59th term of the arithmetic sequence <br> 29,37,45,...
liberstina [14]

Answer:

13,456

Step-by-step explanation:

Tn= a+(n-1)d

a is the first term, n is the given number and d is the common difference. d is given by subtracting the first term from the second term or the second from the third. Therefore the the 59th term of the sequence 29, 37, 45 is,

Tn= 29+(59-1)8

=29(58)8

=13,456

If cos(x)=1/4 what is sin(x) and tan(x)
anygoal [31]
You can use the identity
  cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.

  (1/4)² +sin(x)² = 1
  sin(x)² = 1 - 1/16
  sin(x) = ±(√15)/4


Then the tangent can be computed as the ratio of sine to cosine.
  tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
  tan(x) = ±√15


There are two possible answers.
In the first quadrant:
  sin(x) = (√15)/4
  tan(x) = √15

In the fourth quadrant:
  sin(x) = -(√15)/4
  tan(x) = -√15

64x-18 = 0
64x=18
x=18/64 =1/3 =0.3
B. 64x+18=0
64x= -18
x =-18/64
x= -1/3
x = -0.3
