Given a pyramid of sabcd whose base is a parallelogram. m is the midpoint of sc.

a) find am cut (sbd) at i. prove that ia = 2im

b) find sd cut (abm) at f. prove that f is the midpoint of sd and abmf is a trapezoid.

c) call n arbitrary ab. find the intersection of mn with (sbd).

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

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
