Answer: D. 771.42 units^3
Step-by-step explanation:
For 
, we expect 
. Then recalling that 
, we have
Then by definition of tangent,
The answer to this question is B) 44.78
To solve this proportion, cross multiply.
By cross multiplying, you will multiply 2.75 * (2/9) and 9 * x.
0.61 = 9x
Divide both sides by 9.
x = 0.067... which rounds to 0.068, so your answer is:
D) x 
0.068
Exactly right down to the last step, but some errors in combining terms.
(6m^5 + 3 – m^3 – 4m) – (–m^5 + 2m^3 – 4m + 6)
= (6m^5 + 3 – m^3 – 4m) + (m^5 – 2m^3 + 4m – 6)
= 6m^5 + 3 + (–m^3) + (–4m) + m^5 + (–2m^3) + 4m + (–6)
= [6m^5 + m^5] + [3 + (–6)] + [(–m^3) + (–2m^3)] + [(–4m) + 4m]
= (6+1)m^5 +(-1-2)m^3 +(-4+4)m +(3-6)
= 7m^5 – 3m^3 – 3
