We can solve this in 2 ways
Since a1 = 4
a2 = 4 * (3) = 12 i.e( a1* common ratio)
a3 = 12 * (3) = 36 i.e( a2 * common ratio)
a4 = 36 * (3) = 108 i.e( a3* common ratio)
a5 = 108 * (3) = 324 i.e(a4*common ratio)
and so on
Using the unit circle, it is found that the approximate decimal value of tan(α) is given by -3.274.
<h3>What is the unit circle?</h3>
For an angle 
the unit circle is a circle with radius 1 containing the following set of points: 
.
In this problem, we have point (-0.292, 0.956), hence 
.
Applying the definition of the tangent, we have that:
.
Hence the second option is correct.

15 minutes is 1/4 of 60 minutes and therefore 1/4 of one hour. If she can type 1,200 words in 1/4 hour, she can type 1200*4 = 4800 words in one hour.
Answer: No
If you convert the 6 ft to inches you should get that the door is 78 inches high and 36 inches wide.
You then convert the 7ft of plywood to inches to see if it can fit. The plywood is 84 inches so it cannot fit.
I’m not sure but this looks like a -87x - 30 and that would be your answer if you were asking about 10x - 97x - 30 so you would just subtract the 10x from the -97x and that would leave you with -87x - 30 and I see no other ways of manipulating it.
