Which best describes the function represented by the table?

trasher [3.6K]

Answer:

Option B is correct.

direct variation; k = 5/2

Step-by-step explanation:

The Direct variation says:

$y \propto x$

then the equation is of the form: $y = kx$ ......[1] where k is the constant of variation.

From the given table:

Consider x = -2 and y = -5

Substitute these in [1] to solve for k;

$-5 = -2k$

5 = 2k

Divide both sides by 2 we get;

$k = \frac{5}{2}$

⇒ the equation becomes: $y = \frac{5}{2}x$

Check:

Take x = 4 and y = 10;

$y = \frac{5}{2}x$

$10 = \frac{5}{2} \times 4$

$10 = 5 \times 2$

10 = 10 True

Therefore, the direct variation ; $k = \frac{5}{2}$ best describe the function represented by the table

A Best Eastern Motel is a regional motel chain. Its rooms rent for $90 per night, on average. The variable cost is $40 a room pe

Vlad1618 [11]

Answer: break even point (y) = 24000

Step-by-step explanation:

This is quite simple to solve,

We will take a step by step calculation.

let us begin;

Given that the Room rent per night is = $90

Also the variable cost per night = $40

Total fixed cost = $1200,000

Now we are asked to solve for the Break even point;

Remember that at break even point, the Revenue = cost

Say the required revenue from renting y rooms R = $90y

The cost of renting y rooms = C = $ (40y + 1200,000)

therefore from this we have the Break even point as

$90y = $ (40y + 1200,000)

where y = 24000

cheers i hope this helps!!!!!!

19, find the direction angle of vector v to the nearest tenth of a degree

labwork [276]

The vector v is given by:
v = (7, 2) - (-5, 0)
v = ((7 - (- 5)), (2-0))
v = ((7 + 5), 2)
v = (12, 2)
Then, the angle is given by:
tan (theta) = 2/12
theta = atan (2/12)
theta = 9.46 degrees
Answer:
The direction angle of vector to the nearest tenth of a degree is:
theta = 9.5 degrees
