Remark

The formula for this series is

t_n = n^2 - 1

Explanation

If the series ends at 288, then the highest value n can have is 17

So you would write t_n = n^2 - 1 {n| 1 ≤ n ≤17}

If you said this to someone, you would say "t_n = n squared minus 1 where n is such that 1 is greater than or equal to 1 or less than or equal  to 17"

Example

What is the 4th term in this series?

t_4 = 4^2 - 1

t_4 = 16 - 1

t_4 = 15

Answer: The first answer choice

Step-by-step explanation:

In the first answer choice, the distance increases for two units, then decreases for three units. The distance then increased for 4 units, stayed level for 3 units, and then decrease slowly for 6 units. The graph exactly follows this trend.

The second answer is <em>immediately wrong</em> because it relates the distance between the car and the concert venue. <em>It never mentioned that the car moved, and the venue obviously can't move</em>.

The third answer says that after the first increase/decrease, Tyler went to go text his friends. However, <em>the graph does not show a flat area after the first increase/decrease</em>.

The fourth answer, like the second answer is immediately wrong because <em>homes and schools can't move</em>.

This is my first response, so I hope it was helpful. :D

Total amount spent on Flooring (427.25+212.52+75) = 714.87

Amount spent on furniture = 714.87 * 1.25= 893.59

3) 13%

Answer:

see below

Step-by-step explanation:

f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5

f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559

g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72

h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337
