A plane is flying at an altitude of 17,000 feet. The angle of depression from

the plane to the airport on the ground is 21°. What is the distance

between the plane and the airport, to the nearest tenth of a foot?

on

the answer is two. hope this !

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

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
