Answer:

D. A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin

Step-by-step explanation:

The given triangle has vertices at R(3,4), S(1,1), and T(5,1)

Translating the the vertices down by 2 units, we apply the rule;

(x,y)\to (x,y-2)

\implies (3,4)\to (3,2)

\implies (1,1)\to (1,-1)

\implies (5,1)\to (5,-1)

Rotating the resulting vertices through an angle 270 degrees counterclockwise, we apply the rule:

(x,y)\to (x,-y)

\implies (3,2)\to R'(2,-3)

\implies (1,-1)\to S'(-1,-1)

\implies (5,-1)\to T'(-1,-5)

Therefore the correct choice is D.

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!!!!!!
