Find the first,fourth,and eighth term of the sequence A(n)=-3x2 ^n-1

1 answer:

7 0

A(n) = 5.3^(n-1)
first term A(1) = 5.3^(1-1)= 5.3^0 = 5.1 = 5
fourth term A(4) = 5.3^(4-1) = 5.3^3 = 5x27 = 135
8th term A(8) = 5.3^(8-1) = 5.3^7 = 5.3^3.3^3.3 = 5x27x27x3= 15x729 = 10935

hope this helps! ;)

Find the distance between the points (-6,-2), (2,7)

Readme [11.4K]

Answer:

$d=12.0416$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(2-(-6))^2+(7-(-2))^2}$

$d=\sqrt{(2+6)^2+(7+2)^2}$

$d=\sqrt{(8)^2+(9)^2}$

$d=\sqrt{64+81}$

$d=\sqrt{145}$

$d=12.0416$

The height of a square prism is 3n + 1. The volume of the prism is 3n³ + 13n² + 16n + 4. What is the area of the square base of

EastWind [94]

If s is the side of the square base, the area of the square base is s^2.
The volume of the square base is,
V = (s²) (h)
s² = V/h
s² = 3n³ + 13n² + 16n + 4 / 3n + 1
You can do this division by factoring, synthetic division, or by plain division.
Factoring out 3n + 1 from the numerator gives you:
s² = (3n + 1)(n² + 4n + 4) / 3n+1
s² = n² + 4n + 4

Therefore, the area of the square base is n² + 4n + 4.

What is 13x -4+100=180

Naddika [18.5K]

Answer: x = 6.46153846

Step-by-step explanation:

We are given the equation 13x - 4 +100 = 180, and we must find the value of x. In order to do that get x on on one side by itself and a constant on the other side by itself.

This first step is to combine like terms. 13x is by itself. -4 + 100 = 96. This gives us the equation 13x +96 = 180.

In order to get x by itself, subtract 96 from each side of the equation. This gives us the equation 13x = 84.

Next, divide each side by 13 to find x. This gives us x = 6.46153846

$13x - 4 +100=180$

$13x + 96 = 180$

$13x = 84$

$x = 6.46153856$

Hope this helps! Have a nice day!
