A²=b²+c²-2bc Cos (a)
In this case , we can find the length of side a using the above cosine law.
If you are given the values of side b , c and angle a, then it is easy to calculate the length of side a.
To find side b,
b²=a²+c²-2ac Cos(b)
To find side c,
c²=b²+c²-2bc Cos (c)
Just the given values in the formula and get the length of the missing side. You can also find the missing angle using these formulas.

I hope this will help you.

Which statements are true about exponential decay functions? Check all that apply. The domain is all real numbers. As the input
lorasvet [3.4K]
<h2>Answer:</h2>

The correct options are:

  • The domain is all real numbers.
  • The base must be less than 1 and greater than 0.
  • The function has a constant multiplicative rate of change.
<h2>Step-by-step explanation:</h2>

We know that the exponential function is given by:

                f(x)=ab^x

where a>0 and b are constants.

Also, it represents a growth function if b>1

and a decay function if 0<b<1

where b is the base.

  • x belongs to whole of the real numbers( since the exponential function is well defined for all the real values of x.

Hence, the domain of the function is all the real numbers )

  • Also, the graph of a decay function decreases continuously i.e. with the increasing input value the output value decreases.
  • The exponential decay function always have a constant multiplicative rate of change i.e. b.
