What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)
ExtremeBDS [4]

Answer:

tan(-π/3) =  -1.732050808

Step-by-step explanation:

Given in the question, we have to find the value of tan(-pi/3) or it can be written as:

x = tan(-\frac{\pi}{3})

where x is the exact value of the given tangent.

However, in this question, one may get confused and put the value of π = 3.14, which is wrong. The value given is in radians, which is used to measure angles, just like degrees.

To make it easier, lets convert the radians into degrees. We know that

π = 180°

-π/3 = -180/3 = -60°

Find x:

x = tan (-60°)

x = -1.732050808

Answer:

The first term of the sequence is -120.

Step-by-step explanation:

The formula for the "nth" term of a geometric sequence is shown below:

an = a0*r^(n-1)

Where an is the nth term, r is the ratio and n is the position of the term on the sequence. For this problem we want to find what is the initial term, a0, so we will isolate it in the formula as shown below:

a0*r^(n-1) = an

a0 = an/[r^(n-1)]

We then apply the data given to us

a0 = 31.45728/[-0.8^(7-1)]

a0 = 31.45728/[-0.8^6] =31.45728 /-0.262144= -120

The first term of the sequence is -120.
