What is the 100th term of the sequence 7, 4, 1, -2 ...

1 answer:

8 0

The sequence is arithmetic as it goes down 3 every time

Arithmetic nth term formula is an=a1+d(n-1)

an=7-3(n-1)
an=7-3n+3
an=-3n+10

To find the 100th term substitute n for 100
a100=-3(100)+10
a100=-300+10
a100=-290

The 100th term is -290

Bradley tv screen is 15 feet by 20 feet he wants to put a cover on the tv screen that costs 25 per square foot how much will it

Lelechka [254]

Area of TV screen = 15 x 20 = 300 square feet
Cost of TV screen cover = 25 cents per square foot
Cost to cover TV screen = 0.25 x 300 = $75

The correct question is
Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 8-x^-1 intersect are the solutions of the equation 4−x = 8-x^-1<span>.
Part B: Make tables to find the solution to 4−x = </span>8-x^-1<span>. Take the integer values of x between −3 and 3.
Part C: How can you solve the equation 4−x = </span>8-x^-1 graphically?

Part A. We have two equations: y = 4-x and y = 8-x^-1
Given two simultaneous equations that are both to be true, then the solution is the points where the lines cross. The intersection is where the two equations are equal. Therefore the solution that works for both equations is when
4-x = 8-x^-1
This is where the two graphs will cross and that is the common point that satisfies both equations.

Part B
see the attached table
the table shows that one of the solutions is in the interval [-1,1]

Part C To solve graphically the equation 4-x = 8-x^-1

We would graph both equations: y = 4-x and y = 8-x^-1

The point on the graph where the lines cross is the solution to the system of equations.

using a graph tool

see the attached figure N 2

the solutions are the points

Rajan had 30 dollars to spend on 3 gifts. He spent 9 1 4 dollars on gift A and 5 4 5 dollars on gift B. How much money did he ha

Lyrx [107]

Answer:

$15 1/10

Step-by-step explanation:

Given that :

Total amount to spend = $30

Amount spent on Gift A = $9 1/4

Amount spent on Gift B = $5 4/5

Amount left to spend on gift C ;

$30 - (9 1/4 + 5 4/5)

$30 - (37/4 + 29/5)

$30 - (185 + 116)/20

$30 - 298/20

30/1 - 298/20

$(600 - 298) / 20

$302/20

$15 2/20

= $15 1/10

Try to match the couples: Randy has blue eyes. Matt is 16 and has brown eyes, Sam is 17 and has green eyes, and Chris has hazel

Ymorist [56]

I srsly don’t know what this is, BUT I have opinions and I did something here. Plus, I was bored. :/

1. Randy and Carla (Because Randy loves her eyes, he sees something in them no one can.)
2. Matt and Megan (Although she’s one year older they are passionate for each other and Matt loves Megan’s deep ocean blue eyes.)
3. Sam and Sabrina (Both are compatible and their love for each other is beautiful. Sam sees Sabrina capable of more than Sabrina believes in herself. And Sabrina is obsessed with how Sam’s eyes speak.)
4. Chris and Rhonda (Chris loves Rhonda. They fell in love at first site, Chris knew it was something about her green grass eyes, and Rhonda felt full when she looked into his warm autumn hazel eyes.)
