I don't think the correct y-intercept is offered as one of the choices.

                                         <u>  y = 2 (x + 3) (x - 4)</u>

Where the graph crosses
the y-axis, x=0 :                  y = 2 (0 + 3) (0 - 4)

                                           y = 2 ( 3 )  ( -4 )

                                           y = 2 ( -12 )  =  <em>-24

URGENT!!! Write the product as a sum or difference.
CaHeK987 [17]

Answer:

3 sin(41t) - 3 sin(t)

Step-by-step explanation:

The general formula to convert the product of the form cos(a)sin(b) into sum is:

cos(a) sin(b) = 0.5 [ sin(a+b) - sin (a-b) ]

The given product is:

6 cos(21t) sin(20t) = 6 [ cos(21t) sin(20t) ]

Comparing the given product with general product mentioned above, we get:

a = 21t and b = 20t

Using these values in the formula we get:

6 cos(21t) sin(20t) = 6 x 0.5 [ sin(21t+20t) - sin(21t-20t)]

= 3 [sin(41t) - sin(t)]

= 3 sin(41t) - 3 sin(t)

Therefore, second option gives the correct answer
