Answer: 
<u>Step-by-step explanation:</u>
NOTE: Neither the Trapezoidal Rule or Reimann Sums can be used without the number of rectangles (n) you are separating the interval into. Besides, they only provide an estimate. If you want the EXACT area, you must use integration.
We know: The sum of the angles of each quadrilateral is 360°.
Therefore we have equation:
x + 3x + 4x + 2x = 360
10x = 360 |:10
x = 36
Answer:
The quadratic equation is x^2-2x-4
Step-by-step explanation:
We want to know the equation that has the solution below;
x = 1 ± √5
This means x = 1 + √5 or 1 - √5
The equation would thus be;
(x-1-√5)(x-1+ √5)
= x(x-1+ √5)-1(x-1+ √5)-√5(x-1+ √5)
Opening the brackets we have ;
x^2-x+ √5x-x + 1 -√5-√5x+ √5-5
collecting like terms we have;
x^2-2x+1-5
= x^2-2x-4
Answer:
$3,400,000
Step-by-step explanation:
170,000/ 5% for the increase
170,000/ 5% = $3,400,000
9.95 , rounded to the nearest hundredths :)
