Answer:

Please check explanations

Step-by-step explanation:

Mathematically;

csc 2 theta = 1 / sin 2 theta

Sin 2 theta = sin (theta + theta)

= 2sin theta cos theta

So therefore;

csc 2 theta = 1/2(sin theta cos theta)

= 1/2 * 1/sin theta * 1/ cos theta

1/sin theta = csc theta

1/cos theta = sec theta

Thus;

csc 2 theta = 1/2 * csc theta * sec theta

csc 2 theta = 1/2 sec theta csc theta

Mrac [35]
You can use the simple interest formula 
P = irt

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
I = 25000(0.03)(7)
I = 5250

The company needs to invest $5250 today, to make $25000 in 7 years.
