10. (07.01 LC) The figure below shows a triangular piece of cloth:

38
5 in.
What is the length of the portion BC of the cloth? (5 points)
O 5 cos 38°
cos 38°
5
O sin 38
5
O 5 sin 38°

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

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.

i believe the answer is the polygon, heptagon.

i am not sure :
