Consider pentagon PQRST. Starting at P and moving around the pentagon, the vertices are labelled P, Q, R, S, and T, in order. The pentagon has right angles at P, Q, and R, obtuse angles at S and T, and an area of 1000 cm2. Point V lies inside the pentagon such that ZPTV, ZTVS, and ZV SR are right angles. Point U lies on TV such that ASTU has an area of 210 cm². Also, it is known that PQ = 50 cm, SR= 15 cm, and TU = 30 cm. Determine the length of PT.

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
