Will give brainliest a bird fountain is located 6 m from the base of joey's apartment building. from his window, joey can see it at a 51 degree angle of depression. to the nearest tenth of a meter, how far up the building is joey's window? a) 4.9 m b) 7.4 m c) 7.7 m d) 9.5 m

Option B. 7.4 m.

Step-by-step explanation:

Angle of depression given = 51°

Distance of the fountain from the building = 6 m

We have to find the height of the window from the ground.

Now tan 51° = height of window/ distance of building from the fountain.

1.23 = height of window/6

height of window = 6×1.23 = 7.40 m.

Option B. is the answer.

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
