Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2

If t varies 1/s and t=2 when s=60 find the relationship between t and s, b, find the value of t when s=90 c, find s when t=2,1/2
suter [353]

Answer:

t = k \frac{1}{s}  \\ 2 = k. \frac{1}{60} \\ k = 120 \\ k \:  \: is \: constant \: of \: variation \\ relationship \: is  \\ t =  \frac{120}{s} . \\ when \: s \:  = 90 \\ t =  \frac{120}{90}  \\ t =  \frac{4}{3}  \\ when \: t = 2 \frac{1}{2}  \\ s =  \frac{120}{2 \frac{1}{2} }  \\ s = 48

Vladimir [108]

The names of the functions in the attached figure are:

  • Cubic function
  • Absolute value function
  • Square root function.
  • Rational function.
  • Quadratic function

<h3>How to name the functions?</h3>

Functions can be named by their parent functions.

This is so because functions derive their properties from their parent functions.

There are several parent functions, some of them are:

  • Linear equation
  • Exponential equation
  • Quadratic equation
  • Rational equation
  • Logarithmic equation
  • Square root equation
  • Cubic equation
  • Cube root equation

Using the above as a guide, the names of the functions in the attached figure are:

  • Cubic function
  • Absolute value function
  • Square root function.
  • Rational function.
  • Quadratic function
