What does the y-intercept represent? the amount of water that is added to the barrel each day the amount of water that remains in the water barrel the amount of water that is initially in the water barrel the amount that the water barrel decreases each day

The amount of water that is initially in the water barrel

Step-by-step explanation:

Let's assume we have a function

y=f(x)

y-intercept means y-value when x=0

so,

y=f(0)

and x=0 means initial value

So, y-intercept means initial value of quantity

here, y is  amount of water

x is time

so,

y-intercept will be the amount of water that is initially in the water barrel

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
