Read it and solve it for me
AnnyKZ [126]

Answer:

a. y + 9 + x + y + x + 4 + x + 5 = 2x + 2y + 18

b. 30.4cm

c. Area of big rectangle = 9y cm², Area of small rectangle = 4x cm²

d. a = 9y + 4x

e. a = 38.8

Step-by-step explanation:

a. Perimeter = y + 9 + x + y + x + 4 + x + 5

                     = x + x + y + y + 9 + 4 + 5

                     = 2x + 2y + 18

b. 2x + 2y + 18 = 2(3.4) + 2(2.8) + 18

                        = 6.8 + 5.6 + 18

                        = 30.4cm

c. Formula for area of rectangle: length × breadth

Area of big rectangle = 9 × y

                                    = 9y cm²

Area of small rectangle = 4 × x

                                       = 4x cm²

d. a cm² = (9y + 4x)cm²

e. a = 9y + 4x

      = 9(2.8) + 4(3.4)

      = 25.2 + 13.6

      = 38.8

The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, sold by the company:
Volgvan

The answers to the various part as well as its reasons are given below

<h3 /><h3>Part A:</h3>
  • The x-intercepts shows a zero profit.
  • The maximum value of the graph tells  or depict the maximum profit.
  • The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
  • This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
  • The  profits are negative as seen on the left of the first zero and on the right of the second zero.

<h3>Part B:</h3>

An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from  3 to 5.

<h3>Part C:</h3>

Based on the above,  the domain is one that is held back or constrained by x = 0 .

We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.
