Question

Please help MEDALLL!!!

Answer 1

Yes, at a point with a positive x-coordinate

Answer 2

f(x)=x^2+2
g(x)=2x+1

Answer 3

Thank you soo much! Would you mind maybe looking at a few other questions as well?

Answer 4

Ok.

Answer 5

A coach wants to know if football players who warm up before a game will score more points than those who don't warm up. He will break the team up into two groups and make sure each player gets equal time on the field. He will then count how many points each player makes during the game. What statistic should he study?

The mean number of points earned by each player

The mean number of points earned by each group

The standard deviation of the number of points earned by each player

The standard deviation of the number of points earned by each group

Answer 6

The mean number of points earned by each group

Answer 7

Thank you! I only need two more:

1. Find the sum of a finite geometric sequence from n = 1 to n = 7, using the expression −4(6)n − 1.

111,325

526

782

-223,948



2. What is the x-coordinate for the minimum point in the function f(x) = 4 cos(2x − π) from x = 0 to x < 2π?

x = pi over 2

x = pi over 4

x = 2π

x = π

Answer 8

Let me retype that

Answer 9

Find the sum of a finite geometic sequence from n=1 to n=7, using the expression: -4(6)^n-1

111,325

526

782

-223,948

Answer 10

The second question is:

What is the x-coordinate for the minimum point in the function f(x)=4cos(2x-pi) from x=0 to x < 2pi

x = pi over 2

x = pi over 4

x = 2pi

x = pi

Answer 11

The second one is 2pi. I'm not sure for the first one, sorry.

Answer 12

That's alright, thank you so much I really appreciate it :)

Answer 13

No problem :)

Answer 14

The first one that Admiral couldn't solve is -223,948. I know this is 10 months later, but future viewers can have an answer.
