<h3>Answer:</h3>

4 m

<h3>Explanation:</h3>

If we let h represent the height of the sail, then its width is h/2. The area of the sail is given by ...

... A = (1/2)wh

Filling in the given information, we have

... 4 m² = (1/2)(h/2)h

... 16 m² = h² . . . . . . multiply by 4

... 4 m = h . . . . . . . . take the square root

Inventory was taken on Day 1, Day 2, Day 5, Day 6, and Day 7. Norris wants to know roughly what the inventory was on Day 3.
Dvinal [7]

He should evaluate the function f(x)=−1/3 x+4 for x=3  , Option D is the correct answer.

<h3>What in Interpolation ?</h3>

Interpolation is when the line of best fit is used to determine the value of a point that is within the range of plotted points.

It is given to find the value at Day 3 which lies in the range of the points used for plotting

The line for best fit is

f(x) = (-1/3)x +4

At x = 3

f(3) = (-1/3) * 3 +4

f(3) = -1+4 = 3

Therefore He should evaluate the function f(x)=−1/3 x+4 for x=3

Option D is the correct answer.

Rus_ich [418]

Answer:

1287

Step-by-step explanation:

Number of people in elevator , n = 8

Number of floors, r = 6

Since they all look alike, arrangement doesn't matter, the we use combination :

(n+r-1 r - 1) = (8+6-1 C 6-1) = 13C5

Recall:

nCr = n! / (n-r)!r!

13C5 = 13! / (13-5)!5!

13C5 = 13*12*11*10*9 / 5*4*3*2*1

= 1287
