Answer:
See below.
Step-by-step explanation:
Convert the cotangent to cosine over sine:
Use the cofunction identities. The cofunction identities are:
To convert this, factor out a negative one from the cosine and sine.
Recall that since cosine is an even function, we can remove the negative. Since sine is an odd function, we can move the negative outside:
Answer:
156.37°
Step-by-step explanation:
We solve this above question, using Cosine rule which is given as:
Cos C = a² + b² - c²/2ab
Let the Angle be represented as: x
Cos x = 310² + 200² - 150²/2 × 310 × 200
x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]
x = 23.63°
The angle, in degrees, that he must turn through to head straight for Island B is given as:
180° - 23.63°
= 156.37°

Answer:
0.58 or 58%
Step-by-step explanation:
If the highest probability is 1, and you already have 0.42, you have to find what is left, so our equation is:
1 - 0.41 = 0.58
So the probability of getting a head is 0.58 or 58%
The total amount of money he only made is calculated by
the formula:
amount made = 15,200 – 912
amount made = 14,288
Therefore the percentage commission was:
% commission = 912 / 14,288 * 100%
<span>% commission = 6.38 %</span>
