Mathematics
1 answer:
xxMikexx [17]2 years ago
5 0

Answer:

  • 8x² + 8x - 2

Step-by-step explanation:

<u>We know that:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • Length of rectangle = 4x² - x + 2
  • Width of rectangle = 5x - 3

To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".

<u>Solution:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • => 2[{4x² - x + 2} + {5x - 3}] = Perimeter
  • => 2[4x² - x + 2 + 5x - 3] = Perimeter
  • => 2[4x² + {-x + 5x} + {2 - 3}]
  • => 2[4x² + 4x - 1]
  • => 8x² + 8x - 2

Hence, the perimeter of the rectangle is 8x² + 8x - 2.

Given the function g(x) = x2 + 10x + 20, determine the average rate of change of
Dmitrij [34]

A function assigns the values. The average rate of change for the given function g(x) is 1.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The average rate of change of a function is given by the formula,

Average rate of change, = [f(b)-f(a)]/(b-a), [a,b]

Where a is the lower limit and b is the upper limit.

Given the upper limit for the function is 0, therefore, the value of a is 0, similarly, the value of b is -9. Thus,

a = 0

g(a) = 0²+10(0)+20 = 20

b = -9

g(b) = (-9)²+10(-9)+20 = 11

The average rate of change for the function g(x), can be written as,

\text{Average rate of change}= \dfrac{g(-9)-g(0)}{-9-0}=\dfrac{11-20}{-9} = 1

Hence, the average rate of change for the given function g(x) is 1.
