Answer:
9°
Step-by-step explanation:
You can make use of any of the trigonometric ratios to determine N, or you can let your calculator tell you what it is by solving the triangle.
SOH CAH TOA reminds you that
... sin(N) = 13/85 . . . . N = arcsin(13/85)
... cos(N) = 84/85 . . . N = arccos(84/85)
... tan(N) = 13/84 . . . . N = arctan(13/84)
all will tell you N ≈ 8.79741° ≈ 9°
_____
If you use inverse functions on your calculator, be sure it is in <em>degrees mode</em>.
2 solutions. This is because the parabola will cross the x axis twice. We know this because -5 means the vertex will be 5 units below the x axis. and the parabola opens upwards because the first coefficient is positive. Hope this helped :)
Question # 17 Solution
Answer:
Step-by-step Explanation:
The given expression
And we have to solve for x₁
So,
Lets solve for x₁.
Multiply both sides by x₂ - x₁
Divide both sides by -m
Therefore,
Question # 23 Solution
Answer:
Step-by-step Explanation:
The given expression
And we have to solve for n
So,
Let's solve for n.
Multiply both sides by b.
Factor out n.
Divide both sides by -b + x.
Therefore,
