Can someone me the graph of f(t) = 3 x 2^t shows the value of a rare coin in the year t. what is the meaning of the y-intercept?

B. When it was purchased (year 0), the coin was worth $3.

Step-by-step explanation:

We have been given graph of function , which represents the value of a rare coin in the year t. We are asked to tell the meaning of the y-intercept.

We know that y-intercept is the point, where graph intersects y-axis. It is also known as the initial value.

The y-intercept of the function will be at . Upon substituting in our given formula, we will get:

So, the y-intercept of our given function would be 3.

Since the given function represents the value of a rare coin in the year t, so y-intercept tell us that the value of coin is $3, when it was purchased and option B is the correct choice.

(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
