The explicit rule for a sequence is an=5(−2)^n−1
Murrr4er [49]

Answer:

3) a_n=-2a_{n-1}, a_1=5

Step-by-step explanation:

Given that the explicit rule for a sequence is a_n=5(-2)^{n-1}.

Now we need to find about what is the recursive rule for the sequence and match with the given choices to find the correct choice.

1) a_n=-2a_{n+1}, a_1=5

2) a_n=-5a_{n+1}, a_1=2

3) a_n=-2a_{n-1}, a_1=5

4) a_n=-5a_{n-1}, a_1=2

Plug n=1 into given formula to get first term

a_n=5(-2)^{n-1}

a_1=5(-2)^{1-1}=5(-2)^{0}=5(1)=5

base of the exponent part is (-2) so that means we need to multiply -2 to the previous term to get nth term

Hence correct choice is: 3) a_n=-2a_{n-1}, a_1=5

diamong [38]

Answer: Ordinal

We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.

For example : In an exam we arrange position of students as :

First > Second > Third and so on.

Given : A group of women tried five brands of fingernail polish and ranked them according to preference. It means she is arranging the brands in an order .

Thus this is an ordinal level of measurement .

eimsori [14]

Answer:

512 ft.

Step-by-step explanation:

From the parking lot at the Red Hill Shopping Center, the angle of sight (elevation) to the top of the hill is about 25. From the base of the hill you can also sight the top but at an angle of 55. The horizontal distance between sightings is 740 feet. How high is Red Hill? Show your subproblems.

Solution:

Let x be the distance from the base of the hill to the middle of the hill perpendicular to the height, let h be the height of the hill. Therefore:

tan 25 = h/(x + 740)

h = (x + 740)tan 25       (1)

tan 55 = h / x

h = x tan 55        (2)

Hence:

(x + 740)tan 25 = xtan 55

0.4663(x + 740) = 1.428x

0.4663x + 345.07 = 1.428x

0.9617x = 345.07

x = 359 ft.

h = xtan55 = 359 tan(55) = 512 ft.
