Answer:
The correct option is B
Step-by-step explanation:
Given information: ∠F=32°,∠D=54° and DF=18m.
According to the angle sum property of triangle, the sum interior angles of a triangle is 180°.
Using angle sum property, we get





Law of sine:

Using law of sine we get




Cross multiply,

Divide both sides by 0.99756405026.


The value of EF is 14.6 m. Therefore the correct option is B.
Answer:
<u>maximum of 2 bicycle</u>
Step-by-step explanation:
Given the average cost per bicycle modeled by the equation
C(x) = 0.5x^2-1.5x+4.83
C(x) is in hundreds of dollars
x is number of bicycle
The number of bicycle that will minimize the cost occurs when dC/dx = 0
dC/dx = 2(0.5)x - 1.5
dC/dx = x - 1.5
Since dC/dx = 0
0 = x - 1.5
x = 0+1.5x = 1.5
Hence the shop should buy <u>maximum of 2 bicycle</u> to minimize the cost
I think it would be how much a car weighs as a cars weight will vary with the make and model
