You just need to substitute 20 for x and then solve.

a(20) = -5 +(20-1)3

Simplify: a(20) = -5 + (60-3)

Simplify: a(20) = -5 + 57

Result: a(20) = 52

So, 52 is the 20th term of the arithmetic sequence.

In the equation
a(n) =  - 5 + (n - 1)3
Let n=20 and evaluate it as:

a(20) =  - 5 + (20 - 1)3 \\  \\ a(20) =  - 5 + (19)3 \\  \\ a(20) =  - 5 + 57 \\  \\ a(20) = 52

What are the vertical and horizontal asymptote of f(x)=2x/x-1
makvit [3.9K]
F(x)=2x/(x-1)

Denominator cannot be equal 0.
x-1=0
x=1  is vertical asymptote.

To find horizontal asymptote
we need divide the coefficients before x
y=2x/x=2,because when x becomes really big (x---->∞) , value of 1 will not influence the result .
 y=2 is horizontal asymptote

a circular native american dwlelling has a diameter of 24 feet. how much are inside the home? use 3.14 for { } (pi)
Marizza181 [45]

Answer :

A = 452.16  \: {ft}^{2}

step-by-step explanation:

From the question,

the diameter:

d = 24 \: ft

The radius :

r =  \frac{diameter}{2}=  \frac{24}{2}=12 \: ft

\pi = 3.14

Area of a circle is given as

A = \pi {r}^{2}

By substitution,

A = 3.14( {12}^{2} )

\implies \: A = 3.14 \times 144

\implies \: A = 452.16  \: {ft}^{2}

Hence the area of the home is

A = 452.16  \: {ft}^{2}
