Answer:

Step-by-step explanation:
The recursive rule tells you the initial term of the sequence is a1 = -3, and the common difference is d=7. (7 is the value added to one term to get the next term.)
Putting these values into the formula for the explicit rule gives ...
an = a1 +d(n -1)
an = -3 + 7(n -1)

Step-by-step explanation:
5-7-12 right triangle
According to Soh Cah Toa, the angle you are looking for is sin(x) = 7/12. Solve.
20X0.3= 6
30X0.3= 9
40X0.3= 12
Answer:
