The ordered pairs are:
<span>{(1, 80), (2, 240), (3, 720), (4, 2160)}

with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160

The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3

The equation is:
a_n = 80 * 3^(n - 1)</span>

7. What is the slope of the line that passes through the pair of points (3, 8) and (9, 5) ? (1 point)

agasfer [191]

7. D
8. D
9. D
10.C

for 7 & 8 you use the equation
$\frac{y2 - y1}{x2 - x1}$
your points are (3,8) & (9,5)

so you plug the numbers in
y2= 5
y1=8

x2=9
x1=3
you subtract them get a fraction and that is your slope

9 & 10
use the equation
$y - y1 = m(x - x1)$
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation

suppose your high school basketball team scored 5 runs in saturdays game. this was four more than 1/2 the runs scored by the opp

nalin [4]

Answer:

x = 2

Step-by-step explanation:

Given that:

Your score = 5

We have to find scores of opposite team let it be x

According to given conditions:

Opponents score: (1/2)x+ 4 = 5

By simplifying:

subtract 4 from both sides:

(1/2)x + 4 -4 = 5-4

(1/2)x = 1

Multiply both sides by 2 we get

2*(1/2)x = 1*2

x = 2

Proof:

(1/2)x+ 4 = 5

Put x= 2

(1/2)*2 +4 =5

1 +4 =5

5=5

Hence proved

I hope it will help you!

What is the simplest form of this expression?<br> (1-3)<br> w

Natasha2012 [34]

Answer:

-2w

Step-by-step explanation:

If you distribute w with 1 and 3 you will get 1w - 3w. Since the variables are the same, then you subtract 1w from 3w which will give you -2 as the answer.

Can someone please check this? Thanks!

Answer:

Your choice is correct.

Step-by-step explanation:

The amplitude (multiplier of sin( )) is half the diameter, so is 17.5. The midline (value added to the sine function) is the difference between the maximum (50) and the amplitude (17.5), so is 50-17.5 = 32.5. All choices have the correct frequency.

The function will look like ...

f(t) = 17.5·sin(2πt/5) +32.5 . . . . . as you have marked

. A law firm is run by four partners (A; B; C; D) . Each partner has one vote and decisions are made by majority rule, but in th

ozzi

Answer:

1) (ABCD) (ABC) (ABD) (ACD) (BCD) (AB) (AC) (AD)

2) A= 0.5000; B = 0.1667; C = 0.1667; D = 0.1667

Step-by-step explanation:

The questions are missing and should be

1) List all the winning coalitions in this voting system and the critical players in each.

2) Find the Banzhaf power index of this law firm.

1) Any combination of three partners, four partners, or a combination with two partners containing A is a winning coalition:

(ABCD) (ABC) (ABD) (ACD) (BCD) (AB) (AC) (AD)

2) The Banzhaf power index for each partner is given by the number of outcomes that said partner has a swing vote, divided by the number of possible swing vote situations.

Partners B, C, D will only have swing votes (change the outcome of the voting) when they are all in the same coalition, or when they are alone in a coalition with partner A:

$B_B=2\\B_C=2\\B_D=2$

As for partner A, they will only be powerless to change the outcome when all of the other partners are in the same coalition (2 out of 8 possible combinations):

$B_A=6\\$

The Banzhaf power index for each partner is:

$B=\frac{2}{2+2+2+6}=0.1667\\C=\frac{2}{2+2+2+6}=0.1667 \\D=\frac{2}{2+2+2+6}=0.1667 \\A=\frac{6}{2+2+2+6}=0.5000$
