Two boats start their journey from the same point a and travel along directions ac and ad, as shown below:

what is the distance, cd, between the boats?

The distance CD, between the boats is 115.47 feet.

Step-by-step explanation:

Since we have given that

In Δ ABC,

AB = 100 feet

So, we will use "Tangent " to get the value of BC.

Similarly, we consider, Δ ABD, we will use "Tangent" to get the value of BD.

Hence, the distance CD, between the boats is 115.47 feet.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
