Answer:

\large\boxed{x=2,\ -2}

Step-by-step explanation:

\text{If the trapezoid EFGH is isosceles, then the angles}\ HEF\ \text{and}\ GFE\\\\\text{are congruent. Therefore}\ m\angle HEF=m\angle GFE.\\\\\text{We have the equation}\\\\4x^2+16=5x^2+12\qquad\text{subtract 16 from both sides}\\\\4x^2=5x^2-4\qquad\text{subtract}\ 5x^2\ \text{from both sides}\\\\-x^2=-4\qquad\text{change the signs}\\\\x^2=4\to x=\pm\sqrt4\\\\x=-2\ or\ x=2

The number of visitors p to a website in a given week over 1-year period is given by p(t)=119+(t-83)e^0.02t , where t is the wee
KATRIN_1 [288]

The function p(t) for the number of visitors over 1-year is an exponential function

  • The increasing interval is: [33,52]
  • The decreasing interval is: [0, 33]
  • There is no critical point

<h3>The increasing and the decreasing interval</h3>

The function is given as:

p(t) = 119 + (t-83)e^0.02t

Start by plotting the graph of the function p(t).

From the graph (see attachment), we have the parameters to be:

  • Increasing: [33,52]
  • Decreasing: [0, 33]
  • Critical point = None

Hence, the function has no critical point
