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°
The answer is 68cm^2. Hope this helps!
The exponential form of the regression 9.68(1409)^x .
An exponential function is described as a characteristic with a nice regular other than 1 raised to a variable exponent. A function is evaluated with the aid of solving at a specific input price. An exponential model can be found when the boom fee and preliminary cost are recognized.
As Harvard commercial enterprise review put it, “The incremental mindset makes a speciality of making something higher, at the same time as the exponential mindset makes a speciality of making something distinct. Incremental is glad with just five percent.
The exponential characteristic is a mathematical feature denoted by using f(x)=exp or e^{x}. Until in any other case specific, the term commonly refers to the fine-valued function of a actual variable, despite the fact that it is able to be extended to the complicated numbers or generalized to other mathematical items like matrices or Lie algebras.
