Let the number be x.
x - 25 = -50
x = -50 + 25
x = -25
Hence, the number is -25.
Answer:
2√2 / 3 (first answer choice)
Step-by-step explanation:
If tan Ф < 0, then Ф must be in either Quadrant II or Quadrant IV.
If sin Ф = +1/3, then Ф (for this problem) is in Quadrant II.
Remembering that sin Ф = opp / hyp = 1 / 3, we use the Pythagorean Theorem to find the adj side:
adj² + 1² = 3², or
adj² + 1 = 9, or adj² = 8. Since Ф is in Quadrant II, adj is negative.
The value of cos Ф = adj / hyp = √8 / 3 = 2√2 / 3
= a^3 +3a^2-7a+4a^2+12a-28
=a^3 +7a^2+5a-28
136/1700=0.08
0.08*100=8
The interest rate would be 8%
